CGAffineTransformMakeRotation counter clockwise always

clockwise for an angle greater than 180 degrees In response to comments maybe this will help In my code I actually use rotationAnimation.fromValue rotationAnimation.toValue instead of rotationAnimation.byValue. The rotation is always going to be counter clockwise.. than 180 degrees In response to comments maybe this will help In my code I actually use rotationAnimation.fromValue rotationAnimation.toValue instead of rotationAnimation.byValue. The rotation is always going to be counter clockwise if the toValue is less.. maybe this will help In my code I actually use rotationAnimation.fromValue rotationAnimation.toValue instead of rotationAnimation.byValue. The rotation is always going to be counter clockwise if the toValue is less than the fromValue. It doesn't matter..

Is there a way to pause a CABasicAnimation?

http://stackoverflow.com/questions/2306870/is-there-a-way-to-pause-a-cabasicanimation

this would be to cause the animation to complete instead of calling remove on it how would I do that CABasicAnimation rotationAnimation rotationAnimation CABasicAnimation animationWithKeyPath @ transform.rotation.z rotationAnimation.toValue NSNumber numberWithFloat.. cause the animation to complete instead of calling remove on it how would I do that CABasicAnimation rotationAnimation rotationAnimation CABasicAnimation animationWithKeyPath @ transform.rotation.z rotationAnimation.toValue NSNumber numberWithFloat M_PI 2 rotationAnimation.duration.. that CABasicAnimation rotationAnimation rotationAnimation CABasicAnimation animationWithKeyPath @ transform.rotation.z rotationAnimation.toValue NSNumber numberWithFloat M_PI 2 rotationAnimation.duration 100 rotationAnimation.cumulative YES rotationAnimation.repeatCount..
