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

As discussed here, you can also use a CAAnimation. This code applies one full 360 rotation:

Swift 3

let fullRotation = CABasicAnimation(keyPath: "transform.rotation")
fullRotation.delegate = self
fullRotation.fromValue = NSNumber(floatLiteral: 0)
fullRotation.toValue = NSNumber(floatLiteral: Double(CGFloat.pi * 2))
fullRotation.duration = 0.5
fullRotation.repeatCount = 1
button.layer.add(fullRotation, forKey: "360")

You will need to import QuartzCore:

import QuartzCore

And your ViewController needs to conform to CAAnimationDelegate:

class ViewController: UIViewController, CAAnimationDelegate {

}
