I&#39;m just using &lt;kbd&gt;Command&lt;/kbd&gt; + &lt;kbd&gt;D&lt;/kbd&gt; (Duplicate) for now, as it (AFAIK) is essentially a one-step copy-paste, and dealing with the bug.

You can duplicate views if you drag them with ALT key. it does quickly

Select the ViewController you want to duplicate. press `Command+C`(copy) then `Command+V`(paste).

The new command is `Shift+Command+S`. You can also optionally click `File` and then `Duplicate`.

You can duplicate a view (or scene) easily by selecting the whole view, then copy and paste. 

To copy and paste UI elements, select the element you want to copy, then copy it and paste it **in the original view**. Then drag the newly pasted element to the new view. Everything mouse-based.

When fetching or pulling from git repositories, or cloning a repository, I get to this point: 

    remote: Counting objects: 6666, done.
    remote: Compressing objects: 100% (5941/5941), done.
    Receiving objects:  23% (1534/6460), 11.68 MiB | 23 KiB/s  

And it hangs. The 23%/number of objects isn&#39;t a given, it ranges from single digits to up to the 60s, it seems. Also the speed for download listed freezes -- it&#39;s not like it slowly crawls down towards zero.

The guy I sit next to has no issues, so it&#39;s not a router problem. We use beanstalk for our work repositories, but I have the issue from beanstalk and github (although occaisonally it seems a github one will finish). 

The problem has only seemed to crop up since upgrading to Mountain Lion and updating Xcode. I&#39;ve wiped git (including XCode&#39;s) and tried installing it with homebrew. That didn&#39;t work, so I removed it and tried with their provided Mac installation package which also didn&#39;t fix the issue. 

Beanstalk provides SSH urls for the git repository, but I&#39;ve had no issues with connecting via SCP or SSH to servers that I&#39;ve done work on. 

This is killing my workflow so any help would be much appreciated!

I am trying to create a restful wcf web service.    When I try to connect to the service through the client I get the following error:

&gt;&gt;**The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as &#39;Allowed&#39; or &#39;Required&#39;.**

Is there a quick way to duplicate a scene in Xcode&#39;s storyboard editor?

I&#39;m looking for something akin to using option-drag to duplicate UI elements (`UIButton`, etc.) within a scene (or nib file). Copy-paste works, but awkwardly.

When using GCD, we want to wait until two async blocks are executed and done before moving on to the next steps of execution. What is the best way to do that?

We tried the following, but it doesn&#39;t seem to work:

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
        // block1
    });


    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
        // block2
    });

    // wait until both the block1 and block2 are done before start block3
    // how to do that?

    dispatch_sync(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
        // block3

When I click on my `UITableViewCell`, the background part (the areas that my background image doesn&#39;t cover) turns blue when I click on the cell. Also, all of the `UILabel`s on the cell turn to white when it is clicked which is what I want.

However what I do not want is the blue background when I click it but if I do `selectionstylenone`, then I lose the highlighted colours for the `UILabel`s in the cell.

So is there any way to just get rid of the blue background when the cell is clicked but to keep the highlighted colors of the `UILabel`s?

Custom UITableViewCell selection style?

Seems like `UITextAlignmentCenter` is deprecated in iOS 6. 

I still use it and works well, but it gives a warning.

How can I fix this?

    label.textAlignment = UITextAlignmentCenter;

 
Thanks.



Label Alignment in iOS 6 - UITextAlignment deprecated

I have a mobile app (currently IOS and soon Android) which talks to a web service. There is no login and the data is not private. Basically, the app POSTs a marker (lon, lat) and GETs the nearest 25 markers to display on a map.

It&#39;s a very trivial app and I cannot imagine anyone putting great effort into abusing the web service. However, I can see there is fun for someone in POSTing many markers. What most concerns me is someone running a script that pushes many requests (using expensive bandwidth and making nonsense of my app data).

I am slowly reaching the conclusion this cannot be secure. The best answer is &quot;do not do this&quot;. Do not provide a web service without authentication. Not many services are so open. Google&#39;s You Tube API is open but most are not. Unfortunately, I have no choice. So after days of looking at this here&#39;s my thinking. Be aware I am very far from a security expert and I am confident my approach could be improved upon. But it might point you in the right direction. Hopefully, someone more experienced might chime in and correct/improve upon this. I found [this article][1] and comments particularly helpful.

**Message Level Security**

I will secure the msgs with a hash encryption. The clients and web service all retain a copy of a shared secret which is used as a salt to create a hash from the URL and all the POST arguments. The hash is passed as an additional argument and the hash is rebuilt and compared at the other end (using the shared key as a salt). This is pretty good until you understand that any mobile client code can be reverse engineered in minutes. At which point this line of defense is utterly useless.

**Client Measures**

The client includes rate limiting of messages as a measure to restrict the number of messages sent by honest users. Yet again this is useless against an attacker who jailbreaks the mobile device.

**Server Side Security**

So the server side must have as much additional security measures as possible, to stand alone on the assumption that your client (and shared secret) is compromised. Here is what I have:

One msg arg is a UTC time which is used to limit replay attacks. This should prevent an attacker from firing the same msg at the server repeatedly.

The server performs rate limiting by IP. Yes, IPs are easily spoofed and proxy switching is childs play but everything helps when you have so little.

Of course, the server strictly validates all arguments, uses parametised queries and doesn&#39;t return exceptions.

**Transport Level Security**

Unfortunately, I am fairly confident that issuing individual client SSL certs is not possible without a registration process. And because I am using the msg hash check (and my data is not private) I am not entirely sure what SSL brings to the table. However, I will probably use SSL (with one app wide cert) because it adds another level of security that is easily and cheaply deployed (albeit at a cost of additional connection time for every msg).

**The Gaping Great Big Hole In My Approach**

I am warned that should the app become popular that someone will compromise the shared secret on the client. Just because they can and they will probably post it on the internet. So really it all comes down to the server side. Unfortunately, *I have no way to identify and block an attacker*. This I would dearly love. 

**A Final Plea**

After days of research this is all I have. But I want more. I would particularly appreciate any ideas to beef up the server side. So, I have put all my SO points up as a bounty. Yes sir, all 97 points!

How To Secure Web Service Without Login

I want to reload data in UIViewController when application become active or become foreground.

I know applicationDidBecomeActive is called in AppDelegate class.&lt;br&gt;
But I have to have a global variable for the UIViewController to reload its data in AppDelegate class like this code:

    in AppDelegate.m

    // global variable
    UIViewController *viewController1;
    UIViewController *viewController2;

    -(void)applicationDidBecomeActive:(UIApplication *)application
    {
        [viewController1 reloadData];
        [viewController2 reloadData];
    }


But it is inconvenient especially when I have a lot of UIViewControllers.

Can I use applicationDidBecomeActive in UIViewController instead of in AppDelegate class?&lt;br&gt;
Or are there better ways than having global variable for UIViewController?


I also need to use the following method from UIViewControllers:

    -(void)applicationWillResignActive:(UIApplication *)application
    -(void)applicationDidEnterBackground:(UIApplication *)application
    -(void)applicationWillEnterForeground:(UIApplication *)application


How can I use applicationDidBecomeActive in UIViewController?

After installing the CocoaLumberjack&#39; log compressor class I&#39;ve been getting this annoying behavior: Xcode complains that there are many undeclared identifiers and gives me many errors (not warnings but errors with the red icon). 

The thing is that I can compile and run my iPad app just fine but Xcode won&#39;t do any autocompletion. I tried cleaning the build folder (Product &gt; &lt;kbd&gt;option&lt;/kbd&gt; + Clean), and also deleting derived data. I&#39;ve also rebooted to no avail. 

As you can imagine this is a pain to work with. I did have this behavior happen before on a previous version of Xcode; it had something to do with stuff in my precompiled headers file but using the solution above would always fix it. I&#39;m currently using Xcode 4.4 (4F250).

Sample error I&#39;m getting:

`Semantic Error: use of undeclared identifier &#39;DDTTYLogger&#39;`

The above happens even with classes that I wrote myself and that have *not changed* since installing the CocoaLumberjack compressor class.

Xcode shows many errors but program compiles and runs fine (in both simulator and device)

How do I obtain a Certificate Signing Request? All I&#39;m trying to do is get my app running on my ipod touch. This was easy as I could just go to the IOS development portal and just download one, no muss no fuss. But now they want me to create a CSR to create a provisioning profile and I don&#39;t know how. I&#39;ve been derping around in Keychain Access and the online documents for the better part of two hours and I&#39;m still completely lost. 

I&#39;m not even sure why I need one now when I didn&#39;t before. I had a provisioning profile before I recently switched from Snow Leopard to Mountain Lion, but now it won&#39;t take it. Yes, I&#39;m still on the same computer.

When I&#39;m validating my app I get this error: 

&gt; the application bundle does not contain an icon in ICNS format, containing both a `512x512` and a `512x512@2x` image.
 
I use to make the icns icons with [Img2icns][1] app and until today it always worked properly. But now I&#39;m getting that error and there&#39;s no way to make it work. I tried to put two PNG files together (`512x512` and `1024x1024`) in [Img2icns][2] but I always get that error. I also tried to follow the instructions in Apple&#39;s OS X Human Interface Guideline but when I try to make the icon sets I get this terminal error:

&gt; -bash: syntax error near unexpected token &#39;newline&#39;

I am not very good with terminal commands so maybe I&#39;m doing something wrong. I wrote:

    iconutil -c icns &lt;/Users/myname/SDK Mac Apps/MyApp/grafica/icon.iconset&gt;

If anyone could help it would be very much appreciated. Thanks, Massy.

iOS 6 and Xcode 4.5 has a new feature referred to as &quot;Unwind Segue&quot;:

&gt; Unwind segues can allow transitioning to existing instances of scenes in a storyboard

In addition to this brief entry in Xcode 4.5&#39;s release notes, UIViewController now seem to have a couple of new methods:

    - (BOOL)canPerformUnwindSegueAction:(SEL)action fromViewController:(UIViewController *)fromViewController withSender:(id)sender
    - (UIViewController *)viewControllerForUnwindSegueAction:(SEL)action fromViewController:(UIViewController *)fromViewController withSender:(id)sender
    - (UIStoryboardSegue *)segueForUnwindingToViewController:(UIViewController *)toViewController fromViewController:(UIViewController *)fromViewController identifier:(NSString *)identifier

How do unwind segues work and what they can be used for?

What are Unwind segues for and how do you use them?

Right-clicking the Exit icon yields an empty window. Can&#39;t Ctrl-drag a connection to any IB elements or corresponding source files. Docs give no love. Doesn&#39;t appear in nib files, only storyboards. My assumption is that it&#39;s a corollary to segues, but I don&#39;t see any new methods to back it up. Anyone?

Does anyone know what the new Exit icon is used for when editing storyboards using Xcode 4.5?

I&#39;m just starting my first application using storyboards. I&#39;m using Xcode 4.5 and iOS 6 SDK. I want to know how to change the order in which the controllers are listed in the Document Outline (panel to the left of the storyboard).![enter image description here][1]

Change the listing order of the view controllers in Xcode storyboard

I have a scroll view with content that is 1000px tall and would like to be able to lay it out for easy design on the storyboard.   
I know it can be done programmatically but I really want to be able to see it visually. Every time I put a scroll view on a view controller it won&#39;t scroll. Is it possible to get it to work like I want or do I have to do it in the code?

How to use UIScrollView in Storyboard

I have looked at all the tutorials I can find on this one, and I still don&#39;t have the answer.  I need to call another view from the code.  I am using `UIStoryboards`.  I have changed the view many times by control-dragging from `UIButtons`, but now it must be from the code.  I am trying to call the info page from the main menu if it is the first time the user has opened the app.  I cannot seem to find a way to change the views from the code, however.  All my views are controlled by the same files (**ViewController2**).  The `identifier` of my main menu is **ViewControllerMain**, and the `identifier` of the info page is **ViewControllerInfo**.  First I tried this:

    [ViewControllerMain presentViewController: ViewControllerInfo 
                                     animated:YES 
                                   completion: NULL];

Then I tried making different `UIViewControllers` for each and saying:

    [ViewController2 presentViewController: ViewController 
                                  animated:YES 
                                completion: NULL];

Neither worked.  For the first one, it says:

&gt; Use of undeclared identifier ViewControllerMain.

In the second one, it says:

&gt; unexpected interface name &#39;ViewController&#39;: expected identifier.

What can I do?
