I ended up using

    self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 2, 2);

It allowed me to keep the design created in the Interface Builder.

Unfortunately the sharpness of the image suffers in that case, but this is a small price to pay compared to scripting the whole design programmatically.

Update for Swift 3.0

    self.view.transform = CGAffineTransform(scaleX: 2.0, y: 2.0)


For Swift 4.0, zoom 2x: 

    myView.transform = CGAffineTransform.identity.scaledBy(x: 2, y: 2)

You can first programmatically create those buttons like example create those buttons using the `CGRectMake` method and stating the width and height to be X and Y and multiply by 2 if ipad is detected as for origin it should change respectively too, might cause overlapping if too close to each other

Edit: It all depends on your logic, im unsure too

I have a folder where I need to delete all files and folders except a small list of files and folders.

I can already exclude a list of files, but don&#39;t see a way to exclude a folder and its contents.

Here is the folder structure:

    |-C:\temp
     \-C:\temp\somefile.txt
     \-C:\temp\someotherfile.txt
    | |-C:\temp\foldertodelete
       \-C:\temp\foldertodelete\file1.txt
    | |-C:\temp\foldertokeep
    |  \-C:\temp\foldertokeep\file2.txt

I want to keep somefile.txt and the folder foldertokeep and its content.

This is what I have right now:

    Get-ChildItem -Path  &#39;C:\temp&#39; -Recurse -exclude somefile.txt | Remove-Item -force -recurse

This really does not delete somefile.txt. Is there a way to exclude folder foldertokeep and its content from the delete list?

Delete all files and folders but exclude a subfolder

My goal is to distribute a Python package that has several other widely used Python packages as dependencies.  My package depends on well written, Pypi-indexed packages like pandas, scipy and numpy, and specifies in the setup.py that certain versions or higher of these are needed, e.g. &quot;numpy &gt;= 1.5&quot;.

I found that it&#39;s immensely frustrating and nearly impossible for Unix savvy users who are *not* experts in Python packaging (even if they know how to write Python) to install a package like mine, even when using what are supposed to be easy to use package managers.  I am wondering if there is an alternative to this painful process that someone can offer, or if my experience just reflects the very difficult current state of Python packaging and distribution.

Suppose users download your package onto their system.  Most will try to install it &quot;naively&quot;, using something like:

    $ python setup.py install

Since if you google instructions on installing Python packages, this is usually what comes up.  This will fail for the vast majority of users, since most do not have root access on their Unix/Linux servers.  With more searching, they will discover the &quot;--prefix&quot; option and try:

    $ python setup.py install --prefix=/some/local/dir

Since the users are not aware of the intricacies of Python packaging, they will pick an arbitrary directory as an argument to `--prefix`, e.g. `&quot;~/software/mypackage/&quot;`.  It will not be a cleanly curated directory where all other Python packages reside, because again, most users are not aware of these details.  If they install another package &quot;myotherpackage&quot;, they might pass it `&quot;~/software/myotherpackage&quot;`, and you can imagine how down the road this will lead to frustrating hacking of `PYTHONPATH` and other complications.

Continuing with the installation process, the call to `&quot;setup.py install&quot;` with `&quot;--prefix&quot;` will also fail once users try to use the package, even though it appeared to have been installed correctly, since one of the dependencies might be missing (e.g. pandas, scipy or numpy) and a package manager is not used.  They will try to install these packages individually.  Even if successful, the packages will inevitably not be in the `PYTHONPATH` due to the non-standard directories given to `&quot;--prefix&quot;` and patient users will dabble with modifications of their `PYTHONPATH` to get the dependencies to be visible.

At this stage, users might be told by a Python savvy friend that they should use a package manager like `&quot;easy_install&quot;`, the mainstream manager, to install the software and have dependencies taken care of.  After installing `&quot;easy_install&quot;`, which might be difficult, they will try:

    $ easy_install setup.py 

This too will fail, since users again do not typically have permission to install software globally on production Unix servers.  With more reading, they will learn about the `&quot;--user&quot;` option, and try:

    $ easy_install setup.py --user 

They will get the error:

    usage: easy_install [options] requirement_or_url ...
       or: easy_install --help
    
    error: option --user not recognized

They will be extremely puzzled why their `easy_install` does not have the `--user` option where there are clearly pages online describing the option.  They might try to upgrade their `easy_install` to the latest version and find that it still fails.

If they continue and consult a Python packaging expert, they will discover that there are **two versions** of `easy_install`, both named &quot;`easy_install&quot;` so as to maximize confusion, but one part of &quot;distribute&quot; and the other part of &quot;setuptools&quot;.  It happens to be that only the `&quot;easy_install&quot;` of `&quot;distribute&quot;` supports `&quot;--user&quot;` and the vast majority of servers/sys admins install `&quot;setuptools&quot;`&#39;s `easy_install` and so local installation will not be possible.  Keep in mind that these distinctions between `&quot;distribute&quot;` and `&quot;setuptools&quot;` are meaningless and hard to understand for people who are not experts in Python package management.

At this point, I would have lost 90% of even the most determined, savvy and patient users who try to install my software package -- and rightfully so!  They wanted to install a piece of software that happened to be written in Python, not to become experts in state of the art Python package distribution, and this is far too confusing and complex.  They will give up and be frustrated at the time wasted.

The tiny minority of users who continue on and ask more Python experts will be told that they ought to use `pip/virtualenv` instead of `easy_install`.  Installing `pip` and `virtualenv` and figuring out how these tools work and how they are different from the conventional `&quot;python setup.py&quot;` or `&quot;easy_install&quot;` calls is in itself time consuming and difficult, and again too much to ask from users who just wanted to install a simple piece of Python software and use it. Even those who pursue this path will be confused as to whether whatever dependencies they installed with `easy_install` or `setup.py install --prefix` are still usable with `pip/virtualenv` or if everything needs to be reinstalled from scratch.

This problem is exacerbated if one or more of the packages in question depends on installing a different version of Python than the one that is the default.  The difficulty of ensuring that your Python package manger is using the Python version you want it to, and that the required dependencies are installed in the relevant Python 2.x directory and not Python 2.y, will be so endlessly frustrating to users that they will certainly give up at that stage.

Is there a simpler way to install Python software that doesn&#39;t require users to delve into all of these technical details of Python packages, paths and locations?  For example, I am not a big Java user, but I do use some Java tools occasionally, and don&#39;t recall ever having to worry about X and Y dependencies of the Java software I was installing, and I have no clue how Java package managing works (and I&#39;m happy that I don&#39;t -- I just wanted to use a tool that happened to be written in Java.)  My recollection is that if you download a Jar, you just get it and it tends to work.  

Is there an equivalent for Python?  A way to distribute software in a way that doesn&#39;t depend on users having to chase down all these dependencies and versions?  A way to perhaps compile all the relevant packages into something self-contained that can just be downloaded and used as a binary?

I would like to emphasize that this frustration happens even with the narrow goal of distributing a package to savvy Unix users, which makes the problem simpler by not worrying about cross platform issues, etc.  I assume that the users are Unix savvy, and might even know Python, but just aren&#39;t aware (and don&#39;t want to be made aware) about the ins and outs of Python packaging and the myriad of internal complications/rivalries of different package managers.  A disturbing feature of this issue is that it happens even when all of your Python package dependencies are well-known, well-written and well-maintained Pypi-available packages like Pandas, Scipy and Numpy.  It&#39;s not like I was relying on some obscure dependencies that are not properly formed packages: rather, I was using the most mainstream packages that many might rely on.

Any help or advice on this will be greatly appreciated.  I think Python is a great language with great libraries, but I find it virtually impossible to distribute the software I write in it (once it has dependencies) in a way that is easy for people to install locally and just run.  I would like to clarify that the software I&#39;m writing is not a Python library for programmatic use, but software that has executable scripts that users run as individual programs. Thanks.

I have an UIView with around 50 UIButtons. All button positions were given in pixels, relative to the left upper corner of my main UIView.

All (background) images used in the view are available in higher resolution. As I am porting my app from iPhone to iPad, I would like to increase the effective pixel size of the UIView.

Now I&#39;m searching a way to upscale the whole UIView by a factor of 2*. Is that possible without destroying the position of the inner elements?

FYI, the UIView is designed in a NIB-file in XCode. But I don&#39;t mind if it can be done programmatically.

I&#39;ve setup a UIRefreshControl in my UITableViewController (which is inside a UINavigationController) and it works as expected (i.e. pull down fires the correct event). However, if I programmatically invoke the `beginRefreshing` instance method on the refresh control like:

    [self.refreshControl beginRefreshing];

Nothing happens. It should animate down and show the spinner. The `endRefreshing` method works properly when I call that after the refresh.

I whipped up a basic prototype project with this behavior and it works properly when my UITableViewController is added directly to application delegate&#39;s root view controller, e.g:

    self.viewController = tableViewController;
    self.window.rootViewController = self.viewController;

But if I add the `tableViewController` to a UINavigationController first, then add the navigation controller as the `rootViewController`, the `beginRefreshing` method no longer works. E.g.

    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
    self.viewController = navController;
    self.window.rootViewController = self.viewController;

My feeling is this has something to do with the nested view hierarchies within the navigation controller not playing nice with the refresher control - any suggestions?

Thanks 

UIRefreshControl - beginRefreshing not working when UITableViewController is inside UINavigationController

This isn&#39;t so much a question as an explanation of how to solve this problem.

The first thing to realize is that the `UICollectionView` does inherit from a `UIScrollView` - so doing a standard lookup with a scroll view&#39;s content is the best solution.

Here&#39;s the problem I was addressing:

I had a `UICollectionView` that had differing items in each cell - along with differing types of cells.  I need the selection of a cell to cause an effect of the image in the cell to appear to expand and take over the whole screen.  How I did the expansion is for another post.

The challenge was getting the cell&#39;s position on the screen so that the animating section would have a reference point from where to start.

So, to facilitate getting this information - consider the following code:

First note:  

    UICollectionView *picturesCollectionView;
    DrawingCell cell; // -&gt; instanceof UICollectionViewCell with custom items.

    // first, get the list of cells that are visible on the screen - you must do this every time
    // since the items can change...  This is a CRITICAL fact.  You do not go through the
    // entire list of cells - only those the collectionView indicates are visible.  Note 
    // there are some things to watch out for - the visibles array does not match the indexPath.item
    // number - they are independent.  The latter is the item number overall the cells, while
    // the visibles array may have only 2 entries - so there is NOT a 1-to-1 mapping - keep
    // that in mind.

    NSArray *visibles = [self.picturesCollectionView visibleCells];

    // now, cycle through the times and find the one that matches some criteria.  In my
    // case, check that the cell for the indexPath passed matches the cell&#39;s imageView...
    // The indexPath was passed in for the method call - note that the indexPath will point
    // to the number in your datasource for the particular item - this is crucial.
        
    for (int i=0; i&lt;visibles.count; i++) {
        DrawingCell *cell = (DrawingCell *)visibles[i];
        if (cell.imageView.image == (UIImage *)images[indexPath.item]) {

            // at this point, we&#39;ve found the correct cell - now do the translation to determine
            // what is it&#39;s location on the current screen...  You do this by getting the contentOffset
            // from the collectionView subtracted from the cell&#39;s origin - and adding in (in my case)
            // the frame offset for the position of the item I wish to animate (in my case the
            // imageView contained within my custom collection cell...

            CGFloat relativeX = cell.frame.origin.x - self.picturesCollectionView.contentOffset.x + cell.imageView.frame.origin.x;
            CGFloat relativeY = cell.frame.origin.y - self.picturesCollectionView.contentOffset.y + cell.imageView.frame.origin.y;
                
            // I now have the exact screen coordinates of the imageView - so since I need this
            // to perform animations, I save it off in a CGRect - in my case, I set the size
            // exactly to the size of the imageView - so say you were doing a Flicker display
            // where you wanted to grow a selected image, you get the coordinates of the image
            // in the cell and the size from the displayed image...

            UIImageView *image = cell.imageView;
                
            // selectedCell is a CGRect that&#39;s global for the sake of this code...
        
            selectedCell = cell.frame;
            selectedCell.origin.x = relativeX;
            selectedCell.origin.y = relativeY;
            selectedCell.size.width = cell.imageView.frame.size.width;
            selectedCell.size.height = cell.imageView.frame.size.height;
        }
    }

    // done.  I have my coordinates and the size of the imageView I wish to animate and grow...


Hopefully, this helps other folks that are trying to figure out how to say overlay something on the cell in an exact position, etc...

I&#39;m trying to figure out how to do this with auto layout (iOS6) and constraints.

Basically I have my large view divided up into two sections on the bottom. Inside of those sections (currently subviews) I have an image view and a label. I want to center those on both sides, with variable length text.

My head is mostly wrapped around auto layout, but I&#39;m not sure the best approach to this. I&#39;m inclined to think it&#39;s not possible in IB, but is in code.

Going to continue trying to figure this out, but in the meantime here is the example I&#39;m trying to create.

I am trying to set up a view&#39;s layer properties via IB. Everything works except for color of the border (property `layer.borderColor`):

![enter image description here][1]

I remember running into this problem a year ago and I ended up doing it programatically. And still, I can do this programmatically, but I am curious why the `layer.borderColor`property never works via interface builder. I don&#39;t want to import `QuartzCore`, and then write extra line of code just because of this, seems like an overkill.

I&#39;m using a `UICollectionView` to scroll through a set of thumbnails quickly. Once scrolling ends, I&#39;d like to display a larger hi-res version of the current thumbnail. 

How can I detect when the user has completed scrolling? I do implement `didEndDisplayingCell`, but that only tells me when a particular cell has scrolled off; it doesn&#39;t tell me when the scroll motion actually completes.

I am using push notification service in my app. When app is in background I am able to see notification on notification screen(screen shown when we swipe down from top of iOS device). But if application is in foreground the delegate method

 is getting called but notification is not displayed in notification screen. 

I want to show notification on notification screen independent of whether app is in background or foreground. I am tired by searching for a solution. Any help is greatly appreciated.

I&#39;m looking for a way to add a `padding` property to an UIView. Ideally, I would like to avoid subclassing and putting it in a category. The usage would be something like:


    myview.padding = UIEdgeInsetsMake(10, 10, 10, 10);


And maybe have a `paddingBox` property as well which would return a `CGRect` describing the size and position of the inner padding box.


Now, how would one implement in a category something like that. I initially though of using `bounds`, but unfortunately the size of the `bounds` is linked to the size of the `frame` (always the same) only the coordinates can differ.

If a add a border of a view using code in a view like

    self.layer.borderWidth = 2.0f;
the border is added inside the view like the following:
![enter image description here][1]


the right view is the original view, as you can see, the black area of bordered view is less than the original one. but what I want to get is a border outside of original view, like this:![enter image description here][2]. the black area is equal to original one, how can I  implement it?

I am aware this question has been asked before but the answers are contradicting and I am confused, so please don&#39;t flame me.

I want to have a reusable `UIView` subclass throughout my app. I want to describe the interface using a nib file.

Now let&#39;s say it&#39;s a loading indicator view with an activity indicator in it. I would like on some event to instantiate this view and animate in to a view controller&#39;s view. I could describe the view&#39;s interface no problem programmatically, creating the elements programmatically and setting their frame inside an init method etc.

How can I do this using a nib though? Maintaining the size given in interface builder without having to set a frame.

I&#39;ve managed to do it like this, but I&#39;m sure it is wrong (it&#39;s just a view with a picker in it):

     - (id)initWithDataSource:(NSDictionary *)dataSource {
            self = [super init];
            if (self){
                self = [[[NSBundle mainBundle] loadNibNamed:[NSString stringWithFormat:@&quot;%@&quot;, [self class]] owner:self options:nil] objectAtIndex:0];
                self.pickerViewData = dataSource;
                [self configurePickerView];
            }
            return self;
        }

But I&#39;m overwriting self, and when I instantiate it:

    FSASelectView *selectView = [[FSASelectView alloc] initWithDataSource:selectViewDictionary];
        selectView.delegate = self;
        
        selectView.frame = CGRectMake(0, self.view.bottom + 50, [FSASelectView width], [FSASelectView height]);

I have to manually set the frame rather than have it picked up from IB.

EDIT: I want to create this custom view in a view controller, and have access to control the view&#39;s elements. I don&#39;t want a new view controller.

Thanks

**EDIT: I Don&#39;t know if this is best practice, I&#39;m sure it&#39;s not, but this is how I did it:**

    FSASelectView *selectView = [[[NSBundle mainBundle] loadNibNamed:[NSString stringWithFormat:@&quot;%@&quot;,[FSASelectView class]] owner:self options:nil] objectAtIndex:0];
        selectView.delegate = self;
        [selectView configurePickerViewWithData:ds];
        selectView.frame = CGRectMake(0, self.view.bottom + 50, selectView.width, selectView.height);
        selectView.alpha = 0.9;
        [self.view addSubview:selectView];
        [UIView animateWithDuration: 0.25 delay: 0 options:UIViewAnimationOptionAllowUserInteraction |UIViewAnimationOptionCurveEaseInOut animations:^{
                                selectView.frame = CGRectMake(0, self.view.bottom - selectView.height, selectView.width, selectView.height);
                                selectView.alpha = 1;
                            } completion:^(BOOL finished) {
                            }];

**Correct practice still wanted**

Should this have been done using a view controller and init with nib name? Should I have set the nib in some UIView initialisation method in the code? Or is what I have done ok?

I have a small issue I want to fix, but can&#39;t find any good answer :

When I use a scale on a div (which contains other divs), it leave white space around, from the &quot;original&quot; width and height of my div :

![enter image description here][1] 


  [1]: http://i.stack.imgur.com/chq4G.png

How can I remove the withe space around the div while scaled ?

I can use js if needed !

EDIT: Here is some code :

**HTML**

    &lt;div class=&quot;pull-right nextpack&quot;&gt;

						&lt;div class=&quot;quarter scale-thumb&quot;&gt;

							&lt;div class=&quot;up&quot;&gt;
								&lt;div class=&quot;inner&quot; style=&quot;background-image: url({{URL::base().&#39;/galery/th293x711/&#39;.$nextpack-&gt;src}})&quot;&gt;&lt;/div&gt;
							&lt;/div&gt;

							&lt;div class=&quot;face&quot;&gt;
								&lt;div class=&quot;top&quot; style=&quot;background-image: url({{URL::base().&#39;/galery/th293x711/&#39;.$nextpack-&gt;src}})&quot;&gt;&lt;/div&gt;
								&lt;div class=&quot;bot&quot; style=&quot;background-image: url({{URL::base().&#39;/galery/th293x711/&#39;.$nextpack-&gt;src}})&quot;&gt;&lt;/div&gt;
							&lt;/div&gt;

							&lt;div class=&quot;cote-droit&quot;&gt;
								&lt;div class=&quot;inner&quot;&gt;
									&lt;div class=&quot;cote-droit-top&quot; style=&quot;background-image: url({{URL::base().&#39;/galery/th293x711/&#39;.$nextpack-&gt;src}})&quot;&gt;&lt;/div&gt;
									&lt;div class=&quot;cote-droit-bot&quot; style=&quot;background-image: url({{URL::base().&#39;/galery/th293x711/&#39;.$nextpack-&gt;src}})&quot;&gt;&lt;/div&gt;
								&lt;/div&gt;
							&lt;/div&gt;

						&lt;/div&gt;


					&lt;/div&gt;

**CSS**
(you really don&#39;t need to know how the pack is done, it&#39;s a lot of css3 for nothing, basically just skew, rotate, scale to make a 3D render from a flat template)

    .quarter.scale-thumb
    {
	-webkit-transform: scale(0.2);
	-moz-transform: scale(0.2);
	-o-transform: scale(0.2);
	transform: scale(0.2);
    }


PS : The first pic is when I don&#39;t add the scale-thumb class

Building a CMS of sorts where the user can move around boxes to build a page layout (basic idea anyway).

I&#39;d like to pull the actual contents in from the database and build out the &quot;page&quot;, but have it display at 50% scale.

I realize I could have 2 sets of CSS - one for the actual front-facing page, and one for the admin tool and just shrink everything accordingly, but that seems like a pain to maintain.

I was hoping there might be some kind of jquery or CSS or something that would allow me to populate a div and give it the properties (?) of 50% scale.

&gt; Docker is an open-source project to easily create lightweight,
&gt; portable, self-sufficient containers from any application. The same
&gt; container that a developer builds and tests on a laptop can run at
&gt; scale, in production, on VMs, bare metal, OpenStack clusters, public
&gt; clouds and more.

Let&#39;s say I have a docker image which runs Nginx and a website connects to external database. How do I scale the container in production?

I have a custom class of buttons in a UIView that I&#39;d like to add to an array so that they&#39;re easily accessible. Is there a way to get all subviews of a specific class and add it to an array in Swift?

Swift: Get all subviews of a specific type and add to an array

A Container View can be easily added into a storyboard through Interface Editor. When added, a Container View is of a placeholder view, an embed segue, and a (child) view controller.

However, I am not able to find a way to add a Container View programmatically. Actually, I am not even able to find a class named `UIContainerView` or so.

A name for the class of Container View is surely a good start. A complete guide including the segue will be much appreciated.

&lt;sub&gt;I am aware of View Controller Programming Guide, but I do not regard it as the same as the way Interface Builder does for Container Viewer. For example, when the constraints are properly set, the (child) view will adapts to the size changes in Container View.&lt;/sub&gt;
