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

You can also try to implement an extension which will simplify things if you need to do it multiple time

extension UIView {
    
    func rotate360Degrees(duration: CFTimeInterval = 1, repeatCount: Float = .infinity) {
        let rotateAnimation = CABasicAnimation(keyPath: "transform.rotation")
        rotateAnimation.fromValue = 0.0
        rotateAnimation.toValue = CGFloat(Double.pi * 2)
        rotateAnimation.isRemovedOnCompletion = false
        rotateAnimation.duration = duration
        rotateAnimation.repeatCount = repeatCount
        layer.add(rotateAnimation, forKey: nil)
    }
    
    // Call this if using infinity animation
    func stopRotation () {
        layer.removeAllAnimations()
    }
}
