Rotate a view for 360 degrees indefinitely in Swift?

Question

I want to rotate an image view for 360 degrees indefinitely.

UIView.animate(withDuration: 2, delay: 0, options: [.repeat], animations: {
    self.view.transf         


        

Answer 1

Use this extension to rotate UIImageView 360 degrees.

extension UIView {
func rotate360Degrees(duration: CFTimeInterval = 1.0, completionDelegate: AnyObject? = nil) {
    let rotateAnimation = CABasicAnimation(keyPath: "transform.rotation")
    rotateAnimation.fromValue = 0.0
    rotateAnimation.toValue = CGFloat(M_PI)
    rotateAnimation.duration = duration

    if let delegate: CAAnimationDelegate = completionDelegate as! CAAnimationDelegate? {
        rotateAnimation.delegate = delegate
    }
    self.layer.addAnimation(rotateAnimation, forKey: nil)
}
}

Than to rotate UIImageView simply use this method

self.YOUR_SUBVIEW.rotate360Degrees()
