UIView transitionWithView swift语法 [英] UIView transitionWithView swift syntax

问题描述

有些人可以帮助我使用swift中的transitionWithView语法。在objective-c中我会这样使用它：

Can some help me with the syntax of the transitionWithView in swift. in objective-c I would use it like so:

[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

However I can not get the completion handler to work. thanks

推荐答案

在 Swift 中会是这样的：

UIView.transitionWithView(self.view, duration: 0.325, options: UIViewAnimationOptions.CurveEaseInOut, animations: {

    // animation

    }, completion: { (finished: Bool) -> () in

    // completion

    })
