I have used UIView
animateWithDuration
to increase the shapeLayer.frame.size.height
in the code below, but regardless of the duration it animates very fast. A few posts that I found recommended using some delay time which I've done, but it still animates very quickly, ignoring the 5 seconds duration I set.
private let minimalHeight: CGFloat = 50.0
private let shapeLayer = CAShapeLayer()
override func loadView() {
super.loadView()
shapeLayer.frame = CGRect(x: 0.0, y: 0.0, width: view.bounds.width, height: minimalHeight)
shapeLayer.backgroundColor = UIColor(red: 57/255.0, green: 67/255.0, blue: 89/255.0, alpha: 1.0).CGColor
view.layer.addSublayer(shapeLayer)
}
func delay(delay:Double, closure:()->()) {
dispatch_after(
dispatch_time(
DISPATCH_TIME_NOW,
Int64(delay * Double(NSEC_PER_SEC))
),
dispatch_get_main_queue(), closure)
}
override func viewDidAppear(animated: Bool) {
delay(3) {
UIView.animateWithDuration(5.0) {
self.shapeLayer.frame.size.height += 400.0
}
}
How can I make the animation complete in 5 seconds?
Maybe you should try CABasicAnimation
let fromValue = view2.layer.bounds.height
let toValue = view2.layer.bounds.height + 50
CATransaction.setDisableActions(true) //Not necessary
view2.layer.bounds.size.height = toValue
let positionAnimation = CABasicAnimation(keyPath:"bounds.size.height")
positionAnimation.fromValue = fromValue
positionAnimation.toValue = toValue
positionAnimation.duration = 1
view2.layer.addAnimation(positionAnimation, forKey: "bounds")
