动画子视图

Question

My question is really easy. I just can't figure it out how to animate between subviews.

Here's how I'm animating between VC's.

I'm using Hero transitions for Swift

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
            let main = segue.destination as! ViewController
            main.hero.modalAnimationType = .selectBy(presenting: .zoomSlide(direction: .left), dismissing: .zoomSlide(direction: .right
                ))
}

This is how I'm presenting subview

self.view.addSubview(featureView!)

Answer 1

You can use one of the view transition functions like transition(with:duration:options:animations:completion:) or transition(from:to:duration:options:completion:) . The one with an animations parameter takes a closure that actually performs the transition animation.

The second one that does not take an animations parameter is simpler, and does the transition for you using options flags that you specify.
