How to detect iPhone 5 (widescreen devices)?
Do any adjustments need to be made for an app started in development prior to the iphone 5 in order for them to work on the iphone 5's larger screen?
If so, what are these changes, or where can I find what to change? google hasn't been too helpful so far.
Thanks
After adding the Default-568h#2x.png launch image, follow the steps outlined in this post:
How to develop or migrate apps for iPhone 5 screen resolution?
If you are having issues with the images being used INSIDE the app, and you want to support iPhone 5 and pre-iPhone 5 devices, use this:
Dealing with different size images in a xib for iPhone5 versus iPhone4?
You need to add a default launch images with 640x1136px named Default-568h#2x.png to support the iPhone 5 screen.
First, you have to have a 640x1136 launch image (with -568h#2x.png suffix) to make it compatible with the iPhone 5, but to fully make use of the larger screen, there are a many ways to do it. I find the easiest way to do it is to make two separate storyboards, making a new one for the iPhone 5, while maintaining the one you have already used for the iPhone 4S, 4, etc. Using two storyboards removes the necessity for AutoLayout; enabling AutoLayout, it is good to note, also removes iOS 5 compatibility. Use the code in this answer to get started.
Depending on how your app views are laid out, you may not need to make too many changes. If you have views that resize and are anchored correctly, such as scroll views or table views, they will expand to fill the additional space on the iPhone 5 screen. You need to add an additional launch image for the new screen size too.
the iphone 5's screen is taller so you'd need to have images with a resolution of 1136x640 also included in your images folder. (add -568h#2x at the end of image's filenames)
also, everytime you will adjust your sprites and everything else that goes on the screen, you will need to account for the iphone 5 separately, just like you account for the ipad and the iphone (non retina and retina).

Enabling Autolayout in .xib or .storyboard and adding a splash screen of 640px by 1136px enables iPhone 5 resolution support for the taller screen.
However, doing so, my app started to display some funny things where I assume autolayout is not a great idea.
I am wondering if there is a way to enable iPhone 5 device support, i.e. fix app's resolution without using Autolayout? Maybe I can set in the code?
If yes, then I will have no need to create 2 storyboards or nibs to support iOS5- and iOS6.
If you weren't using Autolayout before, you won't need to use it for iPhone 5 support.
When you're putting your interface together, you just need to check your bindings, and toggle between the taller phone size, and the regular phone size, as described here:
Xcode Storyboard displaying the new iPhone 5 screen size?
If your screens look fine in both screen sizes then you're done.
If you are doing a lot of coding to show your UI, then you'll have more work to do.
I found a great answer a couple weeks ago (link below). You will copy and paste your older iPhone Storyboard, rename it to reflect the iPhone 5, and press the button that expands the screen size, found on the bottom of the layout grid. Some minor coding adjustments might be needed, but this sample code is used in the AppDelegate to detect which device is running, and hence, which Storyboard to use. You'll just have to duplicate your interfaces, but these GUI changes can be made without code and without AutoLayout (also good to note that AutoLayout removes iOS 5--and lower--compatibility)

I'm (still) trying to convert one of my iPhone applications to iPhone 5, but it still looks like this in the simulator...
What am i doing and why won't it fill up the entire screen?
Have you provided a 4" sized launch image? That's the indicator that tells the OS that your application supports the full screen.
Have you selected in your UIView attributes inspector in XCode iPhone 5 screen size?
Please have a look at the url,
iPhone 5 TabBar not functioning in proper position
Now, in xib, at the right side, under 'Interface Builder Document', put a tick-mark on use autolayout and fix your objects in xib accordinlgy.
Download and install Xcode 4.5 GM. Set a 4-inch launch image for
your app. This is how you get 1136px screen height (without it, you
will get 960px with black margins on top and bottom).
Test your app, and hopefully do nothing else, since everything should work magically if you had set auto resizing masks properly. If you didn't, adjust your view layouts with proper auto resizing masks or look into Auto Layout if you only want to support iOS 6 going forward.
Also note: The auto-rotation API has changed completely, take a look at that as well if your application supports any rotation other than default.
I'm looking at the iPhone 5 specs, and see that the screen resolution is 640x1132 or so, which would break some of my manual+storyboard interface layouts. I'm wandering how to make an app so it would either show on iPhone 5 in 640x960 screen (with black bars), or exclude my app from sale to iPhone 5 at all, as I do not want to worry about the interface breaking. Is this possible for existing apps?
Thank you for your input!
Unless you include a Default-568h#2x.png image in your application, it will not run at full iPhone 5 resolution.
In the Apple keynote on the 12th Sept 2012, they said all current applications in the app store would run on the iPhone 5 with without a problem using the black letterbox at the top and bottom.
The way to remove the letterbox is by providing a Default-568h#2x.png image, like duskwuff mentioned. If its not there, the device will run the application will run at 640x960.

How to deal with iPhone 5 screen size?
Watched the iPhone 5 keynote and yes the device height and a resolution of 640 X 1136. So I saw they showed how existing apps which work on that. But I believe if we use native components like tab bar, navigation bar etc. will work fine. But how about custom tab bars, navigation bars and controls which resides relative to the device orientation. So these are my questions.
1) How to handle custom layouts which has custom tab bars, navigation bars, relative contents etc.
2) Welcome screen. We will need 2 sizes right now. So in iPhone 5 do we need another 2 more for normal and retina?
3) If you carefully watched the keynote seems iPhone 5 will cut some portion of view from left and right so there is no any additional change in the app development. Has anybody noticed that?
1) This depends on how you laid them out, you might need to adjust how you set the frame, change autoresizing masks etc, or if iOS 6 only is an option you could move to auto layout. Without knowing your code I cant give much more detail
2) There is no non-retina iPhone 5 so you only need 1 more Default.png size, named Default-568h#2x.png (btw adding this new sized default image is the trigger for iOS to show your app without letterboxing, so for some apps this is the only change which will need to be made)
3) This is the letterboxing I mentioned, it is what all current apps will do on the iPhone 5 until they are updated with a new default.png
My understanding is that all existing apps will work on iPhone 5 and you will just have the black borders. However you will now have the capability to tailor apps to the bigger screen size. I imagine that there will now be a new sized .xib or storyboard that will match the size of the iPhone 5. You will be able to put an if statement in the app delegate to choose which .xib/storyboard to load based on the screen size. unfortunately now I think we will have to create multiple .xib/storyboard files, similar to how universal apps are made at the moment. The file loaded is selected based on the device.
Hope this helps

How to deal with iPhone 5 screen size?
So with the release of iPhone 5 today and a larger screen height, how do we accommodate for different screen sizes across the different iPhone variants in our apps. I understand that apps which are not updated for iPhone 5 will be "letter boxed", but what about backwards compatibility?
Is there a way to check whether the app is running on an iPhone 3, 4 or 5?
You normally don't need that, because checking the hardware is not the right approach.
If you need to base decisions in your app on the screen size, like accomodate to the screen size for your UI, you should… test the screen size, not make some conditions on the hardware. Always test what is really necessary.
Use [UIScreen mainScreen].bounds for that (as you should always have done). Note that even before iPhone 5, one could plug its iPhone on a videoprojector or external screen and display its app on a screen with different resolution than the iPhone. That's why I hope that you never use magic numbers in your code (And if you did, you know why it's bad now ;)) and was already using constants or asking at runtime for the size of your screen.
Anyway, to accomodate for different screen sizes, if you configured your autoresizing mask correctly in your views, your applications will resize automagically. You just need to provide a Default-h568#2x.png launch image and your app will take the full size of the 4" screen.
Moreover, starting iOS6, you will be able to use AutoLayout to do finer constrainted layout of your views. See the WWDC'12 videos sessions that explains it in detail.
Checkout the UIDevice-Hardware extension, it was even recently updated to add support for the iPhone 5.
