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

in Swift 3 :

UIView.animate(withDuration:0.5, animations: { () -> Void in
  button.transform = CGAffineTransform(rotationAngle: CGFloat(M_PI))
})

UIView.animate(withDuration: 0.5, delay: 0.45, options: .curveEaseIn, animations: { () -> Void in
  button.transform = CGAffineTransform(rotationAngle: CGFloat(M_PI * 2))
}, completion: nil)
