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 5. Try this, it worked for me

UIView.animate(withDuration: 3) {
  self.yourButton.transform = CGAffineTransform(rotationAngle: .pi)
  self.yourButton.transform = CGAffineTransform(rotationAngle: .pi * 2)
 }

Answer 2

You can use a trick: start rotating with 180 degrees first and then rotate with 360 degrees. Use 2 animations with delay. Try this.

Swift 2

UIView.animateWithDuration(0.5) { () -> Void in
  button.transform = CGAffineTransformMakeRotation(CGFloat(M_PI))
}

UIView.animateWithDuration(0.5, delay: 0.45, options: UIViewAnimationOptions.CurveEaseIn, animations: { () -> Void in      
  button.transform = CGAffineTransformMakeRotation(CGFloat(M_PI * 2))
}, completion: nil)

Swift 3, 4, 5

UIView.animate(withDuration: 0.5) { () -> Void in
  self.settingsButton.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
}

UIView.animate(withDuration: 0.5, delay: 0.45, options: UIViewAnimationOptions.curveEaseIn, animations: { () -> Void in
  self.settingsButton.transform = CGAffineTransform(rotationAngle: CGFloat.pi * 2.0)
}, completion: nil)

Hope this helps
