Prevent Rotation on ViewController

Question

How can I prevent the rotation on one UIViewController by code ? in more words I want to prevent rotation for one UIViewController not for all

Answer 1

You need to subclass the view controller, and then return NO from shouldAutoRotate

-(BOOL) shouldAutorotate {
    return NO;
}

Answer 2

In Your view controller

-(BOOL)shouldAutorotate {

return YES;

}

-(NSUInteger)supportedInterfaceOrientations {

return UIInterfaceOrientationMaskPortrait;

}
