Why [UIScreen mainScreen].bounds] is not returning full screen size?

Question

I have an app that was created prior to the new iPhone 5 retina widescreen device. Now i am trying to support this high definition widescreen.

I adjust the main ViewController and the main window XIB files so that they are set to Autolayout. I can verify that the width/height displayed via the IB shows 320 x 568.

However, when I run in simulator, i can see that the height is still 480. The code im using to print the height (and width) is in the main view controller's viewWillAppear method:

[UIScreen mainScreen].bounds]

Why is the size.height still 480 instead of 568?

You have to add the iPhone 5 Launch image (Default-568h@2x.png) to your project.

The 568 point tall launch image tells iOS to launch your app in 4" mode. If you don't have this image, your app is treated as a 3.5" app. Even if it is 4" compatible.

wow, an API that has nothing to do with file resources but with hardware but depends on a resource to work! WOW, how crappy is this? – Duck Oct 20 '15 at 19:43
I have this image and my app is still showing with 320 pixels. – quantumpotato Jan 25 '16 at 19:58

Point worth notice - in new Xcode you have to add this image file Default-568h@2x.png to assets
