How to make my app 4inch-ready? My app in iOS6GM simulator looks not 4inch-sized. Is there any option in xcode to use all 4 inches?

Some users have reported that it was fixed after adding the startup image [email protected] (see below). For updating to iPhone5 I did the following:

Autorotation is changing in iOS 6. In iOS 6, the shouldAutorotateToInterfaceOrientation: method of UIViewController is deprecated. In its place, you should use the supportedInterfaceOrientationsForWindow: and shouldAutorotate methods. Thus, I added these new methods (and kept the old for iOS 5 compatibility):

-(BOOL)shouldAutorotate {
  return YES;
}

- (NSUInteger)supportedInterfaceOrientations{
  return UIInterfaceOrientationMaskAllButUpsideDown;    
}

Then I fixed the autolayout for views that needed it.
Copied images from the simulator for startup view and views for the iTunes store into PhotoShop and exported them as png files.
The name of the default image is: [email protected] the size is 640 x 1136 and the screen size 320 x 568.
I have dropped backward compatibility for iOS 4. The reason is that this new Xcode does not support armv6 code any more. Thus, all devices that I am able to support now (running armv7) can be upgraded to iOS 5.

That was all but just remember to test the autorotation in iOS 5 and iOS 6 because of the changes in rotation.

Removing the splash screen images, cleaning the project and readding the splash screen images solved it for me! thank you! – Templas 13/9, 2013 at 11:7

Before iPhone 5 release, I just use

#define kViewHeight 460.f // or 480.f if you don't have a status bar
#define kViewWidth  320.f

But now, I would like to use

#define kViewHeight CGRectGetHeight([UIScreen mainScreen].applicationFrame)
#define kViewWidth  CGRectGetWidth([UIScreen mainScreen].applicationFrame)

instead.

But I'm not sure whether it is a good solution. As you see, you would dispatch CGRectGetHeight([UIScreen mainScreen].applicationFrame) every where you use kViewHeight. I've tried to use

extern float kViewHeight; // in .h
float kViewHeight = CGRectGetHeight([UIScreen mainScreen].applicationFrame) // in .m

but failed with a compile error.

Though it works well, I think there must be a better workaround. ;)

I don't think that using CGRectGetHeight([UIScreen mainScreen].applicationFrame) every time will cause any performance issues – Vaishnava 13/9, 2012 at 9:18

@KaanDedeoglu Thanks for your reply! I've not tested the performance yet. And yes, I think it might not leads much performance problem, that's why I put it here as an answer. ;) – Bosworth 13/9, 2012 at 9:27
