Hi there,
I’ve been going through this fantastic book on animations you have here and I’m having a blast doing so. I’ve come up on my first problem now though. In this chapter, there is an explanation that my animation for the username textfield will do the following:
it appears in the center of the screen, as it was designed in Interface Builder, and starts animating 0.3 seconds later. What gives?
However, I don’t see this happen at all. My animation starts off screen, waits 0.3 seconds, animates on screen and then remains there. Has something changed in Swift or the libraries, am I misunderstanding something, or? I’m unsure about why I’m going and changing the fillMode of the CABasicAnimation if it has no obvious effect.
My code:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
let flyRight = CABasicAnimation(keyPath: "position.x")
flyRight.fromValue = -view.bounds.size.width/2
flyRight.toValue = view.bounds.size.width/2
flyRight.duration = 0.5
heading.layer.add(flyRight, forKey: nil)
flyRight.beginTime = CACurrentMediaTime() + 0.3
flyRight.fillMode = .both
username.layer.add(flyRight, forKey: nil)
flyRight.beginTime = CACurrentMediaTime() + 0.4
flyRight.fillMode = .both
password.layer.add(flyRight, forKey: nil)
...
Any help would be greatly appreciated!
