Question

I am working on iPhone application with both Portrait orientations support (Portrait and Portrait UpsideDown).

In earlier XCode4.5.1, I have resolved this issue by:

• Setting rootViewController in AppDelegate

• Mentioning shouldAutorotateToInterfaceOrientation like this:

  -(BOOL)shouldAutorotateToInterfaceOrientation:    (UIInterfaceOrientation)toInterfaceOrientation {
  
       return UIInterfaceOrientationIsPortrait(toInterfaceOrientation);   }  
  

• Mentioning supportedInterfaceOrientation in info.plist file

Now I am doing the same things for newer XCode but in iPhone simulator v6.0 its not supporting rotation properly.

I have tried with these methods as well:

-(BOOL) shouldAutorotate {

  BOOL returnValue = NO;

  int interface =  [self preferredInterfaceOrientationForPresentation];

  if(UIInterfaceOrientationIsPortrait(interface)) {

    // Code to handle portrait orientation
    returnValue = YES;
  }
  else {

    // Code to handle Landscape orientation
    returnValue = NO;
  }

  return returnValue;
}

- (NSUInteger) supportedInterfaceOrientations {

  return (UIInterfaceOrientationPortrait | UIInterfaceOrientationPortraitUpsideDown);
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
  return (UIInterfaceOrientationPortrait |
          UIInterfaceOrientationPortraitUpsideDown);
}

Please guide me how to support both the Portrait orientations for iOS > 4.3 all the versions.

Thanks in advance,

Why Did Orientation Change to Landscape Stop Working in iOS 6?

Starting in IOS 6.0 there are several orientation changes that stopped my app from rotation out of Portrait.
The fix for me, and the one applicable here, is that you must setRootViewController on the window in your AppDelegate. The earlier answer offers several suggestions that are all correct, but misses the one item that was relevant for me.

In application didFinishLaunchingWithOptions, after:

[window makeKeyAndvisible]

or

[window addSubview: viewController.view];

You must replace with:

if([[UIDevice currentDevice].systemVersion floatValue] >= 6.0) {
    [window setRootViewController:viewController];
} else {
    [window addSubview: viewController.view];
    (or [window makeKeyAndvisible])
}

You also need to add the new shouldAutoRotate instead of the depreciated shouldAutorotateToInterfaceOrientation, but this was easier to find and less crucial for me.

Same with making sure all your orientations are specified in your .plist file.

I did not need to override supportedInterfaceOrientations because I am satisfied with the default orientations (all for iPad UIInterfaceOrientationMaskAll, all but upside-down for iPhone UIInterfaceOrientationMaskAllButUpsideDown).
