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
})
