Rotate UIButton 360 degrees

Question

I\'ve been trying to run an animation that rotates my UIButton 360 degrees using this code:

UIView.animateWithDuration(3.0, animations: {
  self.vin         


        

Answer 1

Swift 4: Animation nested closure is better than animation delay block.

UIView.animate(withDuration: 0.5, animations: { 
  button.transform = CGAffineTransform(rotationAngle: (CGFloat(Double.pi))) 
 }) { (isAnimationComplete) in

       // Nested Block
UIView.animate(withDuration: 0.5) { 
   button.transform = CGAffineTransform(rotationAngle: (CGFloat(Double.pi * 2)))
       }    
}
