Answer 1

You need to define a UIRotationGestureRecognize in the view you want to rotate, and then add a selector method and implement it as follows.

Add this to you viewDidLoad method

 UIRotationGestureRecognizer *rotate = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotation:)]; [myUIViewObject addGestureRecognizer:rotate]; [rotate release]; 

And then we implement the method.

 - (void) rotation:(UIRotationGestureRecognize *) sender { CGAffineTransform myTransform = CGAffineTransformMakeRotation(sender.rotation); sender.view.transform = myTransform; } 

PS. myUIViewObject can be any UIView object that you want to rotate.
