Automatic rotation changes in iOS 6

Some changes have been made to the automatic screen rotation in iOS 6 SDK. For example, for Master-Detail apps, the master viewcontroller does not support screen rotation, and the detail viewcontroller supports screen rotation.

Enable automatic rotation in info. plist or target-Summary, and select the required supported interface orientations. Create uinavigationcontroller + autorotation. H category and disable automatic rotation of the bottom navcontroller as needed:

1234	- (BOOL)shouldAutorotate{ return NO;}

Set in appdelegatewindow.rootViewController
= navController;, BecauseshouldAutorotateToInterfaceOrientation:Slave
Deprecated from iOS 6 and switchsupportedInterfaceOrientations+preferredInterfaceOrientationForPresentation.

1234567891011121314

- (BOOL)shouldAutorotate{ return YES;}- (NSUInteger)supportedInterfaceOrientations{ return UIInterfaceOrientationMaskAllButUpsideDown;}- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{ return UIInterfaceOrientationLandscapeRight;}

Notes:

1. Rootviewcontroller needs to be set for window,[window
addSubview:navController.view];Invalid;
2. shouldAutorotateValid only at the underlying level;
3. presentModalViewControllerThe previous automatic rotation control is invalid.
   CATEGORY solution.
