In VBA, what&#39;s the most straight forward way to test if a string begins with a substring?  Java has `startsWith`.  Is there a VBA equivalent?

Following the instructions at the link below, I successfully built a REST API for my Django application: http://django-rest-framework.org/tutorial/quickstart.

I can test it by doing the following from the Unix prompt:

    curl -H &#39;Accept: application/json; indent=4&#39; -u root:myPassword http://www.myWebsite.com/users/

It works :)

However, I would like to use the Chrome extension Advanced Rest Client to test this same functionality.
I have installed the extension, but I don&#39;t know where/how to put the fields. When I make my educated-guess (as you can see in the screenshot), it rejects it saying &quot;Authentication credentials were not provided&quot;

![screenshot of failing request][1]

How/where should I specify my parameters to the REST API?

How to select Multiple images from UIImagePickerController

How do I properly resize a UICollectionView so that it fully displays its contents? I have tried many things, including setting its frame, calling ``reloadData`` and invalidating the layout:

    self.collectionView.contentSize = CGSizeMake(300, 2000);
    self.collectionView.frame = CGRectMake(0, 0, 300, 2000);
    [self.collectionView reloadData];
    [self.collectionView.collectionViewLayout invalidateLayout];

but none of this has any effect. After pressing the button I still see the initial view, like this:

![collection view only showing part of the content after frame resize][1]

I have a small demo program where I have a data source producing 100 elements. In Interface Builder I initially set the size of the UICollectionView to a small value so that not all elements fit, after that I press a button after which the code above is executed. I expect the UICollectionView to now show all elements, but it doesn&#39;t.

***EDIT:** The demo program can be found at [https://github.com/mjdemilliano/TestUICollectionView][2].*

***EDIT2:** I have observed that the frame update is lost at some point, because if I press the button again, the current frame is back to the old value. After adding some log statements in the button event handler, the log output is:*

    before: frame = {{0, 58}, {320, 331}}, contentSize = {320, 1190}
    update button pressed
    after: frame = {{0, 0}, {300, 2000}}, contentSize = {300, 2000}
    before: frame = {{0, 58}, {320, 331}}, contentSize = {320, 1190}
    update button pressed
    after: frame = {{0, 0}, {300, 2000}}, contentSize = {300, 2000}

*I don&#39;t understand why the frame change is not kept, what is changing it.*

At some point I will replace the hardcoded values by values obtained from the flow layout, but I wanted to rule that out and keep my example as simple as possible.

Context: What I want to do eventually is the following: I have a scrollable view with various controls like labels and images, and a collection view with dynamic content. I want to scroll all that, not just the collection view, therefore I am not using the collection view&#39;s own scrolling facilities, which work fine.

UICollectionView autosize height

So I have two UILabels side by side in Storyboard. The second label should butt up against the right edge of the first one (trailing constraint of 1), but I also need the first label (the one on the left) to set it&#39;s width equal to it&#39;s content size unless it hits a max width. Visually:


------------------
|Label one text| |Label two text|

------------------

And I need the following constraints:

1) Label one should resize width wise unless it hits a max size.

2) Label two should always be butted up against the right edge of label one 

How do I set this up in Storyboard?

Auto Layout to dynamically size uilabel width

Using this tutorial here: [http://www.musicalgeometry.com/?p=1297][1] I have created a custom overlay and image capture with `AVCaptureSession`.

I am attempting to allow the user to switch between the front and back camera. Here is my code in `CaptureSessionManager` to switch cameras:

    - (void)addVideoInputFrontCamera:(BOOL)front {
        NSArray *devices = [AVCaptureDevice devices];
        AVCaptureDevice *frontCamera;
        AVCaptureDevice *backCamera;
        
        for (AVCaptureDevice *device in devices) {
            
            //NSLog(@&quot;Device name: %@&quot;, [device localizedName]);
            
            if ([device hasMediaType:AVMediaTypeVideo]) {
                
                if ([device position] == AVCaptureDevicePositionBack) {
                    //NSLog(@&quot;Device position : back&quot;);
                    backCamera = device;
                }
                else {
                    //NSLog(@&quot;Device position : front&quot;);
                    frontCamera = device;
                }
            }
        }
        
        NSError *error = nil;
        
        if (front) {
            AVCaptureDeviceInput *frontFacingCameraDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:frontCamera error:&amp;error];
            if (!error) {
                if ([[self captureSession] canAddInput:frontFacingCameraDeviceInput]) {
                    [[self captureSession] addInput:frontFacingCameraDeviceInput];
                } else {
                    NSLog(@&quot;Couldn&#39;t add front facing video input&quot;);
                }
            }
        } else {
            AVCaptureDeviceInput *backFacingCameraDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:backCamera error:&amp;error];
            if (!error) {
                if ([[self captureSession] canAddInput:backFacingCameraDeviceInput]) {
                    [[self captureSession] addInput:backFacingCameraDeviceInput];
                } else {
                    NSLog(@&quot;Couldn&#39;t add back facing video input&quot;);
                }
            }
        }
    }

Now in my custom overlay controller I initialize everything like so in `viewDidLoad`:

    [self setCaptureManager:[[CaptureSessionManager alloc] init]];
        
    [[self captureManager] addVideoInputFrontCamera:NO]; // set to YES for Front Camera, No for Back camera
        
    [[self captureManager] addStillImageOutput];
        
    [[self captureManager] addVideoPreviewLayer];
    CGRect layerRect = [[[self view] layer] bounds];
    [[[self captureManager] previewLayer] setBounds:layerRect];
    [[[self captureManager] previewLayer] setPosition:CGPointMake(CGRectGetMidX(layerRect),CGRectGetMidY(layerRect))];
    [[[self view] layer] addSublayer:[[self captureManager] previewLayer]];
    
    [[_captureManager captureSession] startRunning];


The switch camera button is connected to a method called `switchCamera`. I have tried this:

    - (void)switchCameraView:(id)sender {
        
        [[self captureManager] addVideoInputFrontCamera:YES]; // set to YES for Front Camera, No for Back camera
        
    }


When calling this, I get the error `NSLog` from the `CaptureSessionManager` and I cannot figure out why. In `viewDidLoad`, if I set the `fontCamera` to `YES`, it shows the front camera but cannot switch to back, and vice versa.

Any ideas on how to get it to switch properly?

I am using Xcode in a newly created app and when I run the project it does not show in the iOS Simulator and I get the following message:

 &gt; Failed to instantiate the default view controller for UIMainStoryboardFile &#39;Main&#39; - perhaps the designated entry point is not set?

I&#39;ve Googled about it of course and everybody points out that this is happening because Xcode does not know yet which view controller is the initial one. But the weird thing is that I created the app as a page based (also tried single-view and tabbed app options) app and Xcode already had defined a Storyboard for it.

Also, when I go to the main interface option of the project the storyboard (named &quot;Main&quot; by Xcode itself) is set, and in the Storyboard, my view controller is set as the &quot;Initial View Controller&quot;

![Is Initial View Controller][1]

What is wrong?

Here is some code I struggle with for a while.

If you start the fade in animation, the label text fades in.
If I start the fade out animation the the label text fades out.

When I start the `startFade` method, only fade out is shown. How can I wait for the `fadeIn` method to finish visually before starting the `fadeOut` method.

    -(IBAction)startFade:(id)sender{
        [self fadeIn];
        [self fadeOut];
    }

    -(IBAction)fadeIn:(id)sender{
        [self fadeIn];
    }

    -(IBAction)fadeOut:(id)sender{
    [self fadeOut];
    }

    -(void) fadeIn{
        [_label setAlpha:0];
        [UILabel beginAnimations:NULL context:nil];
        [UILabel setAnimationDuration:2.0];
        [_label setAlpha:1];
        [UILabel commitAnimations];
    }

    -(void) fadeOut{
        [UILabel beginAnimations:NULL context:nil];
        [UILabel setAnimationDuration:2.0];
        [_label setAlpha:0];
        [UILabel commitAnimations];
    }

Can anyone think of a reason that the blinking cursor would not show up in a `UITextView`? I have a custom control that is just a subclass of `UIView` and it has a `UITextView` in it, but the cursor doesn&#39;t appear when it gets focus. The keyboard appears, and the text appears as you type, but there is no cursor, and I can&#39;t figure out why.

Any thoughts?...

Cursor not showing up in UITextView

I have a question about `iOS UIKeyboard`.

I have a `UITextField` and I would to have the `keyboard` with only uppercase characters.

I use a `storyboard` and I tried to set the `Cpitalization` as &quot;`All characters`&quot; to `UITextField properties`.

But this not solve my problem...any suggestion?

Using LocalStorage on iPhone with iOS 7 throws this error. I&#39;ve been looking around for a resolvant, but considering I&#39;m not even browsing in private, nothing is relevant.

I don&#39;t understand why localStorage would be disabled by default in iOS 7, but it seems it is? I&#39;ve tested on other websites as well, but with no luck. I even tried testing it using this website: &lt;http://arty.name/localstorage.html&gt;, but it doesn&#39;t seem like it&#39;s saving anything at all for some weird reason.

Has anyone had the same problem, only they&#39;ve had luck fixing it? Should I switch my storage method?

I tried hard-debugging it by only storing a few lines of information, but to no avail. I used the standard `localStorage.setItem()` function to save.

I&#39;m building a screen to scan barcodes, and I need to put a translucent screen behind some `UILabels` to improve visibility against light backgrounds.

Here&#39;s what the screen looks like now:

![enter image description here][1]


  [1]: https://i.stack.imgur.com/jOMKt.png

I&#39;m setting the background color on the `UILabel` to get the translucent boxes. I&#39;ve also created a custom `UILabel` subclass to allow me to set some padding between the edge of the `UILabel` and the text using [this approach](https://stackoverflow.com/questions/3476646/uilabel-text-margin).

As you can see in the screen above, the `UILabel` doesn&#39;t resize correctly to take the padding into account. The &quot;padding&quot; just shifts the text over without changing the width of the label, causing the text to truncate.

Both of these labels will contain text of arbitrary lengths, and I really need the `UILabel` to dynamically resize.

What `UILabel` method can I override to increase the width of the label and factor in the padding?

I am working on an iPad app, using AutoLayout, where if the user enables a certain mode (&quot;heads-up&quot; mode), I want to support only portrait (or portrait upside down) orientation, and furthermore, if the device is in landscape, I&#39;d like to automatically switch to portrait mode.

In the top view controller, I have the following:

    - (NSUInteger) supportedInterfaceOrientations {
        if (self.modeHeadsUp) {
            return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
        } else {
            return UIInterfaceOrientationMaskAll;
        }
    }
    
    - (BOOL) shouldAutorotate {
        return TRUE;
    }

Based on answers I&#39;ve seen elsewhere here, the answer *seems* to be that I should use &quot;application setStatusBarOrientation&quot;. Therefore, in the method where the user has selected &quot;heads-up&quot; mode, I have included:

        UIApplication *application = [UIApplication sharedApplication];
        [application setStatusBarOrientation:UIInterfaceOrientationPortrait
                                    animated:YES];

However, this simply doesn&#39;t seem to do anything. While I can physically move the device to get it to rotate into portrait, it doesn&#39;t do so automatically.

In fact, when in landscape mode after running the above code to attempt to programmatically set the orientation, when I query the application &quot;statusBarOrientation&quot; with the following code, it remains at &quot;4&quot; for landscape:  

    UIApplication *application = [UIApplication sharedApplication];
    int orientation = [application statusBarOrientation];
    self.movesTextView.text = [NSString stringWithFormat:@&quot;ORIENTATION %d&quot;, orientation];

It seemed like maybe autolayout wasn&#39;t being triggered with the setStatusBarOrientation, so I attempted to add this code after, to no effect:

        [super updateViewConstraints];
        [self.view updateConstraints];

I realize Apple wants to leave device orientation in the hands of the user. However, I&#39;d like to be able to support landscape mode when not in &quot;heads-up&quot; mode. 

Am I missing something to be able to force orientation change?

I am going to upload my first mac app to Apple Store

And fixed all validation bugs of icon,category... 

But after then I passed validation with warning :

    The resulting API analysis file is too large. We were unable to validate your API usage prior to delivery. This is just an informational message.

And my upload be rejected with the reason : &quot;Invalid binary&quot;&lt;br /&gt;
Is there anyone has experience of this case ?



----------

UPDATE : this warning is not the reason of rejecting, it maybe the app archiving problem. I successfully released my app to store.

So, we can safely ignore that.

I need to use gdb.

    lrwxr-xr-x   1 pi    admin   30 14 Jan 22:01 gdb -&gt; ../Cellar/isl/0.12.1/share/gdb

Not quite sure what to make this, clearly it is something installed by homebrew. I don&#39;t know why it&#39;s there, I don&#39;t know whether I could use it instead. It isn&#39;t in the search path.

So I figure I need Xcode commandline tools.

https://stackoverflow.com/questions/19907576/xcode-is-not-currently-available-from-the-software-update-server

But how do I check whether I have them already?
