Change or disable the iPhone rotating animation when orientation changes

Question

How do I change or disable the rotating animation when screen orientation changes from landscape to portrait, or vice versa?

Answer 1

If you dont want your view controllers to rotate just override the shouldAutoRotateToInterface view controller method to return false for whichever orientation you dont want to support...Here is a reference.

In the case that u just want to handle rotation some other way, you can return false in the above methods and register for UIDeviceOrientationDidChangeNotification like so

    NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self
       selector:@selector(handleOrientationDidChange:)
           name:UIDeviceOrientationDidChangeNotification
         object:nil];

Now when u get the notifications u can do whatever you want with it...

The answer by @Nils Munch above is find for < iOS7. For iOS 7 or later you can use:

- (void) viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
    [UIView setAnimationsEnabled:NO];

    [coordinator notifyWhenInteractionEndsUsingBlock:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        [UIView setAnimationsEnabled:YES];
    }];

    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
}

Yes, it is possible to disable the animation, without breaking everything apart.

The following codes will disable the "black box" rotation animation, without messing with other animations or orientation code:

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    [UIView setAnimationsEnabled:YES];
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    [UIView setAnimationsEnabled:NO];
  /* Your original orientation booleans*/
}

Place it in your UIViewController and all should be well. Same method can be applied to any undesired animation in iOS.

Best of luck with your project.
