Watch the WWDC 2012 Videos on the subject. There are three 1 hour videos that taught me all I needed to know in order to migrate my apps to Auto-Layout.

If your main issue is the new screen size make sure to add Default-568h@2x.png. This 640 × 1136 image is needed for your app to utilize the iPhone 5's full screen.

Also use

[[UIScreen mainScreen] applicationFrame]

to get the current screen's width and height. Do not hard code 320 width 480 height.

CGRect aFrame = [[UIScreen mainScreen] applicationFrame]; width=aFrame.size.width; height=aFrame.size.height;

  • This makes sense, but as I said above, don't you think apple will create something easier? – RayofHope Oct 22 '12 at 12:59
  • Easier? Thats easy enough Ray. Ray its always better to make your code smarter to overcome simple obstacles such as this. Don't depend on apple making it easier. Will appreciate a 1 or a check Ray. – Begeesy Oct 22 '12 at 20:22

seperate xib files: yes, is one of the possible ways.

autolayout: http://www.raywenderlich.com/20881/beginning-auto-layout-part-1-of-2

(google first hit).

I modified my apps to include autolayout. In all honesty, if I'd have been more proactive I would have designed them with new screen sizes in mind at the start - a mistake I won't make again!

How you approach it really depends on how you designed your original application.

I found and will help others also: https://github.com/mindsnacks/UIImage-MSImageNamed568hSupport

using this we can load 568h size image for iPhone5 if present o.w. load normal image great help...

Example:

#import "UIImage+MSImageNamed568hSupport.h"
.
.
IBimgViewBG.image=[UIImage ms_imageNamed568hSupport:[NSString stringWithFormat:@"sample.png"]];
.
.

Note: include this images in your project

sample.png      // for earlier versions
sample-568h.png // for iphone5

  • Dude, you are basically doing the same thing I showed you below. The first two lines of code are "const CGSize screenSize = [UIScreen mainScreen].bounds.size; const CGFloat screenHeight = MAX(screenSize.width, screenSize.height);" Could of gave me a 1 :( – Begeesy Oct 24 '12 at 19:58
