ios - UIView transitionWithView 快速语法

Question

有人可以帮助我了解 swift 中 transitionWithView 的语法吗？在 objective-c 中我会这样使用它:

[UIView transitionWithView:[ self view ] duration:0.325 options:UIViewAnimationOptionCurveEaseOut animations:
 ^{
     // do the transition
 }
 completion:
 ^( BOOL finished ){
    // cleanup after the transition
 }];

但是我无法让完成处理程序工作。谢谢

在 Swift 5.x 中会像这样:

UIView.transition(with: self.view, duration: 0.325, options: .curveEaseInOut, animations: {

    // animation

}) { finished in

    // completion

}
