Answer 1

Use transform property of you UIButton to translate, rotate or scale its ;-) As Adam Ebernach said, a UIButton is a UIView so you can do all same animation with UIView and UIButton :-)

Answer 2

You can try this

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