With Swift and XCode 6 you can do this.

Click the UIView element in Storyboard, and go to identity inspector. In the user defined runtime attributes, enter:

    layer.borderWidth number 1
If you want nice looking corners

    layer.cornerRadius number 5
    layer.masksToBounds boolean true
Now this will give you a border but to set the colour you need to do it with code. Go to your view controller, and add an IBOutlet from your UIView. Say you do,

    @IBOutlet weak var xView: UIView!
Call this in the viewDidLoad function like below to set the colour.

    xView.layer.borderColor = UIColor.whiteColor().CGColor

Thanks!

With this border, background still appears behind. In other words, the border isn&#39;t projected to outer of view, but to inner space.

I think that is necessary create a overlay view behind the owner with size (width  x height) increased with border size.

It seems in iOS 6, a drop shadow is automatically added to the navigation bar even when you set a custom background image. I&#39;m pretty sure this wasn&#39;t the case with iOS 5 as when I test the same code in the iOS 5 and 6 sim, the shadow appears in iOS 6 but not 5.

Does anyone know anything about this? Or how to enable/disable it?

How do I disable the navigation bar shadow in iOS 6 for navigation bars with custom background images?

How do i simply write out a file including real tabs inside? `tab` means real `tab` which is **not the spaces**. How to write the `tab` or what is the character for real `tab`?

For example here:

    $chunk = &quot;a,b,c&quot;;
    file_put_contents(&quot;chunk.csv&quot;,$chunk);

What character should i use to get `tabs` instead of `Commas (,)` there?&lt;br&gt;
In the output file, there should be real `tabs` between the seperated words.

- Real Tabs means, **a true wide space we get when we press the `&lt;tab&gt;` key** in a text-editor.

I&#39;m looking to have a border around a `UIView` I have just to separate it from the main view visually.

I have looked in the settings for the `UIView` in storyboard editor but I can&#39;t seem to find anything for setting a border.

Is there an easy way to do this in code?

I am new to Xcode (using 4.3) and am not sure how to save an image to the device&#39;s camera roll.  All that I have done so far is set up an IBAction for the button to save the image. What library method or function can I use to save an image to the user&#39;s camera roll?

Ok, here is the deal, I **hate** putting out questions about my debugging and crashes. Because I usually handle them myself, but I just **cannot** get my way around this, even after **viewing multiple questions already**.

Ok so here is the problem, I find my app randomly on and off crashing with this stack trace:


    *** -[ViewController respondsToSelector:]: message sent to deallocated instance 0x1e5d2ef0

Where `ViewController` can vary, sometimes the place where my code crashes, has **NO** relevance to that particular `ViewController` and doesn&#39;t own or call it.

Also, to get that console trace, I have enabled Zombies, otherwise I would get no console print at all, I would only get: `objc_msgSend`, which I know means I am messaging something that is released. But I cannot find where that is... I am really stuck! Usually I **always** debug my crashes, so I am really stuck on this.

Again, this crashes in different places at different times, on and off. And the place it crashes has almost **no** relevance to the `ViewController`. And I find this very confusing. 

Do you need any of my code? I have **a lot** of files and since it is crashing in different places, distributing my code will be a mess!

I have tried to add symbolic breakpoints with no luck, and Zombies is not available on the Instruments application for iOS. I cannot run my app on the simulator as it has unsupportive architecture frameworks for it.

Thanks everyone...

ViewController respondsToSelector: message sent to deallocated instance (CRASH)

Note, for the below question:  All assets are local on the device -- no network streaming is taking place.  The videos contain audio tracks.

I&#39;m working on an iOS application that requires playing video files with minimum delay to start the video clip in question.  Unfortunately we do not know what specific video clip is next until we actually need to start it up.  Specifically: When one video clip is playing, we will know what the next set of (roughly) 10 video clips are, but we don&#39;t know which one exactly, until it comes time to &#39;immediately&#39; play the next clip.

What I&#39;ve done to look at actual start delays is to call `addBoundaryTimeObserverForTimes` on the video player, with a time period of one millisecond to see when the video actually started to play, and I take the difference of that time stamp with the first place in the code that indicates which asset to start playing.

From what I&#39;ve seen thus-far, I have found that using the combination of `AVAsset` loading, and then creating an `AVPlayerItem` from that once it&#39;s ready, and then waiting for `AVPlayerStatusReadyToPlay` before I call play, tends to take between 1 and 3 seconds to start the clip.

I&#39;ve since switched to what I think is roughly equivalent: calling `[AVPlayerItem playerItemWithURL:]` and waiting for `AVPlayerItemStatusReadyToPlay` to play.  Roughly same performance.

One thing I&#39;m observing is that the first AVPlayer item load is slower than the rest.  Seems one idea is to pre-flight the AVPlayer with a short / empty asset before trying to play the first video might be of good general practice. [https://stackoverflow.com/questions/900461/slow-start-for-avaudioplayer-the-first-time-a-sound-is-played]

I&#39;d love to get the video start times down as much as possible, and have some ideas of things to experiment with, but would like some guidance from anyone that might be able to help.

**Update: idea 7, below, as-implemented yields switching times of around 500 ms.  This is an improvement, but it it&#39;d be nice to get this even faster.**

**Idea 1:  Use N AVPlayers (won&#39;t work)**

Using ~ 10 `AVPPlayer` objects and start-and-pause all ~ 10 clips, and once we know which one we really need, switch to, and un-pause the correct `AVPlayer`, and start all over again for the next cycle.

I don&#39;t think this works, because I&#39;ve read there is roughly a limit of 4 active `AVPlayer&#39;s` in iOS.  There was someone asking about this on StackOverflow here, and found out about the 4 AVPlayer limit: [fast-switching-between-videos-using-avfoundation](https://stackoverflow.com/questions/7406300/fast-switching-between-videos-using-avfoundation)

**Idea 2: Use AVQueuePlayer (won&#39;t work)**

I don&#39;t believe that shoving 10 `AVPlayerItems` into an `AVQueuePlayer` would pre-load them all for seamless start.  `AVQueuePlayer` is a queue, and I think it really only makes the next video in the queue ready for immediate playback.  I don&#39;t know which one out of ~10 videos we do want to play back, until it&#39;s time to start that one. [ios-avplayer-video-preloading](https://stackoverflow.com/questions/8354210/ios-avplayer-video-preloading)

**Idea 3: Load, Play, and retain `AVPlayerItems` in background (not 100% sure yet -- but not looking good)**

I&#39;m looking at if there is any benefit to load and play the first second of each video clip in the background (suppress video and audio output), and keep a reference to each `AVPlayerItem`, and when we know which item needs to be played for real, swap that one in, and swap the background AVPlayer with the active one.  Rinse and Repeat.

The theory would be that recently played `AVPlayer/AVPlayerItem`&#39;s may still hold some prepared resources which would make subsequent playback faster.  So far, I have not seen benefits from this, but I might not have the `AVPlayerLayer` setup correctly for the background.  I doubt this will really improve things from what I&#39;ve seen.

**Idea 4: Use a different file format -- maybe one that is faster to load?**  

I&#39;m currently using .m4v&#39;s (video-MPEG4) H.264 format.  H.264 has a lot of different codec options, so it&#39;s possible that some options are faster to seek than others.  I have found that using more advanced settings that make the file size smaller increase the seek time, but have not found any options that go the other way.

**Idea 5: Combination of lossless video format + AVQueuePlayer**

If there is a video format that is fast to load, but maybe where the file size is insane, one idea might be to pre-prepare the first 10 seconds of each video clip with a version that is bloated but faster to load, but back that up with an asset that is encoded in H.264.  Use an AVQueuePlayer, and add the first 10 seconds in the uncompressed file format, and follow that up with one that is in H.264 which gets up to 10 seconds of prepare/preload time.  So I&#39;d get &#39;the best&#39; of both worlds:  fast start times, but also benefits from a more compact format.

**Idea 6: Use a non-standard AVPlayer / write my own / use someone else&#39;s**

Given my needs, maybe I can&#39;t use AVPlayer, but have to resort to AVAssetReader, and decode the first few seconds (possibly write raw file to disk), and when it comes to playback, make use of the raw format to play it back fast.  Seems like a huge project to me, and if I go about it in a naive way, it&#39;s unclear / unlikely to even work better.  Each decoded and uncompressed video frame is 2.25 MB.  Naively speaking -- if we go with ~ 30 fps for the video, I&#39;d end up with ~60 MB/s read-from-disk requirement, which is probably impossible / pushing it.  Obviously we&#39;d have to do some level of image compression (perhaps native openGL/es compression formats via PVRTC)... but that&#39;s kind crazy.  Maybe there is a library out there that I can use?

**Idea 7: Combine everything into a single movie asset, and seekToTime**

One idea that might be easier than some of the above, is to combine everything into a single movie, and use seekToTime.  The thing is that we&#39;d be jumping all around the place.  Essentially random access into the movie.  I think this may actually work out okay: [avplayer-movie-playing-lag-in-ios5](https://stackoverflow.com/questions/7882621/avplayer-movie-playing-lag-in-ios5)


Which approach do you think would be best?  So far, I&#39;ve not made that much progress in terms of reducing the lag.

This is a **WEB APP** not a native app. Please no Objective-C NS commands.

So I need to detect &#39;pinch&#39; events on iOS. Problem is every plugin or method I see for doing gestures or multi-touch events, is (usually) with jQuery and is a whole additional pluggin for every gesture under the sun. My application is huge, and I am very sensitive to deadwood in my code. All I need is to detect a pinch, and using something like jGesture is just way to bloated for my simple needs.

Additionally, I have a limited understanding of how to detect a pinch manually. I can get the position of both fingers, can&#39;t seem to get the mix right to detect this. Does anyone have a simple snippet that JUST detects pinch?

I have a UIView, it is not inside UIScrollView. I would like to move up my View when the keyboard appears. Before I tried to use this solution: https://stackoverflow.com/questions/1126726/how-to-make-a-uitextfield-move-up-when-keyboard-is-present.

It was working fine. But after inserting the data in the textfields, it takes me to another view, and when I get back to this page, its just jumping, and I couldn&#39;t see my text fields. Is there any better solution for this problem?

I want to know how to simply mask the visible area of a UIView of any kind. All the answers/tutorials I&#39;ve read so far describe masking with an image, gradient or creating round corners which is way more advanced than what I am after.

Example: I have a UIView with the bounds (0, 0, 100, 100) and I want to cut away the right half of the view using a mask. Therefore my mask frame would be (0, 0, 50, 100).

Any idea how to do this simply? I don&#39;t want to override the drawrect method since this should be applicable to any UIView.

I&#39;ve tried this but it just makes the whole view invisible.

    CGRect mask = CGRectMake(0, 0, 50, 100);
    UIView *maskView = [[UIView alloc] initWithFrame:mask];
    viewToMask.layer.mask = maskView.layer;

When dismissing a modal view controller using `dismissViewController`, there is the option to provide a completion block. Is there a similar equivalent for `popViewController`?

The completion argument is quite handy. For instance, I can use it to hold off removing a row from a tableview until the modal is off screen, letting the user see the row animation. When returning from a pushed view controller, I would like the same opportunity.

I have tried placing `popViewController` in an `UIView` animation block, where I do have access to a completion block. However, this produces some unwanted side effects on the view being popped to.

If there is no such method available, what are some workarounds?
