Is it part of a view? Do you have your viewController for your view return YES to the shouldAutoRotate method?

When I have my buttons and images on my views and do the above, they automatically rotate when I rotate the device.

Or do you mean by itself, not by rotating the device. Meaning having a button rotated 60 degrees from the view the user sees?

No, I want the UIButton only to turn x amount of degrees depending on how much the user swipes the button. Not the actual device.

You could try this tutorial. If anything, It could get you on the right track?

Rotate an Image or Button with Animation – Part 2

Ok I got some nice code here to turn 180 degrees but how would I modify this code so it turns based upon how much a user swipes the button in each direction?

Heres the code

CABasicAnimation *halfTurn;
halfTurn = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
halfTurn.fromValue = [NSNumber numberWithFloat:0];
halfTurn.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
halfTurn.duration = 0.5;
halfTurn.repeatCount = 1;
[myButton addAnimation:halfTurn forKey:@"180"];
