Scale/Rotate a button in interface

Question

I need to rotate a button by 30 degrees in iphones sdk interface builder, how do you do that???

Thank you in advance

Answer 1

I'm not sure that you can do it directly. You might be able to do it if you were drawing your own buttons via CoreGraphics layers.

Core Animation Layers

Answer 2

You can't do it in Interface Builder, but the code is pretty straightforward.

Make sure you've connected the button in IB to an IBOutlet of type UIButton* (let's call it myButton). Then once the nib has been loaded (for example, in your viewDidLoad method) you can use something like this:

#define RADIANS(degrees) ((degrees * M_PI) / 180.0)

CGAffineTransform rotateTransform = CGAffineTransformRotate(CGAffineTransformIdentity,
         RADIANS(30.0));

myButton.transform = rotateTransform;

Answer 3

             [UIView beginAnimations:nil context:nil];

 [UIView setAnimationDuration:0.5];

 button.transform=CGAffineTransformMakeRotation((0.0174532925)*30);

 //put the -ve sign before 30 if you want to rotate the button in the anticlockwise else use this one 

 [UIView commitAnimations];
