Question

Can anyone confirm that to support both iOS 6 and iOS 5 there is no point to adding the new iOS 6 autorotation methods, since the Apple docs suggest that these methods are c

Answer 1

to support autorotations in both ios5 and ios6 we need to provide call backs in case of ios6....

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(orientationChanged:) 
    name:UIDeviceOrientationDidChangeNotification object:nil];

and we need to call

- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;

} 

-(BOOL)shouldAutoRotate{
    return YES;
  }

for ios5

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return ((toInterfaceOrientation == UIInterfaceOrientationPortrait) || (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown));
}
