I am creating an animation which brings an image and a label from the left to the centre of the view.
imageLogo.isHidden = true
is not hidden when App is run labelLogo
is not shown at all on the viewI have been reading tutorials, but I just don't see what is wrong with my code.
let paymentLogo = UIImage(named: "paymentImage")
var imageLogo:UIImageView!
var overlayView = UIView()
var logoAppeared:Bool!
let labelLogo = UILabel()
override func viewDidLayoutSubviews() {
//move picture off the screen here
self.imageLogo = UIImageView(image:paymentLogo)
imageLogo.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
imageLogo.center.x -= 400
self.view.addSubview(imageLogo)
self.labelLogo.frame =
CGRect(x: 0, y: 0, width: 200, height: 21)
self.labelLogo.center.x -= 400
self.labelLogo.text = "Booking Completed"
self.labelLogo.textAlignment = .center
self.view.addSubview(labelLogo)
}
override func viewDidAppear(_ animated: Bool) {
UIView.animate(withDuration: 2.0, delay: 0.1, options: [], animations: {
//animate paymentCompletedLogo
self.overlayView = UIView(frame: self.view.frame)
self.overlayView.backgroundColor = UIColor.black
self.overlayView.alpha = 0.4
//animate labelLogo
self.labelLogo.frame = CGRect(x: self.view.center.x, y: 90, width: 200, height: 21)
self.labelLogo.backgroundColor = UIColor.gray
self.labelLogo.text = "Booking Completed"
self.labelLogo.textColor = .black
self.labelLogo.textAlignment = .center
//animate imageLogo
self.imageLogo.frame =
CGRect(x: self.view.center.x,y: self.view.center.y,width: 100,height: 100)
self.view.addSubview(self.overlayView)
self.view.addSubview(self.imageLogo)
self.view.addSubview(self.labelLogo)
}) { finished in
self.overlayView.isHidden = true
self.imageLogo.isHidden = true //it is not hidden in simulator
self.logoAppeared = true
}
}

I tried removing following your code from animation method it worked fine. You are trying to add subview in animation method. imageLogo and labelLogo is all ready added in view.
self.view.addSubview(self.overlayView)
self.view.addSubview(self.imageLogo)
self.view.addSubview(self.labelLogo)
