UIViewPropertyAnimator • From iOS 10.0 • UIViewΛॊೈʹΞχϝʔγϣϯͰ͖Δ • Animation start
/ stop • Custom animation curve
Animation with UIViewPropertyAnimator • Old UIView Animation • UIView.animate(withDuration: 1.0,
delay: 0.0, options: UIView.AnimationOptions.curveEaseInOut, animations: { self.pinkView.center.y += 300 }, completion: {finished in })
Animation with UIViewPropertyAnimator • UIViewPropertyAnimator let easeInOutAnimator = UIViewPropertyAnimator( duration:
1.0, curve: UIView.AnimationCurve.easeInOut, animations: { self.pinkView.center.y += 300 }) easeInOutAnimator.startAnimation()
Animation Curve and easing • UIView.AnimationCurve Linear EaseIn EaseOut EaseInOut
Animation Curve and easing • EaseInOut EaseOut EaseIn position time
Custom Animation with UIViewPropertyAnimator • Customize with controlPoint • let
customAnimation = UIViewPropertyAnimator( duration: 2.0, controlPoint1: CGPoint(x: 0.41999998688697815, y: 0.0), controlPoint2: CGPoint(x: 0.5799999833106995, y: 1.0), animations: { })
