问题描述

There is a vertical cover transition. I have been looking around the web for how to do a horizontal cover with no success. Any suggestions?

推荐答案

iOS 中没有提供水平覆盖过渡.您必须创建自己的 UIStoryboardSegue 子类并实现自己的过渡动画.

There's no horizontal cover transition provided in iOS. You'll have to create your own UIStoryboardSegue subclass and implement your own transition animation.

我认为您正在寻找的过渡动画的一种方法是这样的(警告:未经测试的代码):

One way to animate the kind of transition I think you're looking for is something like this (warning: untested code):

// add newView to window
[oldView.window insertSubview:newView aboveSubview:oldView];

// assuming newView and oldView both sized to fill screen,
//   position newView just to the right of oldView
newView.center = oldView.center + oldView.frame.size.width;

// slide newView over oldView, then remove oldView
[UIView animateWithDuration:0.3
                 animations:^{ newView.center = oldView.center; }
                 completion:^(BOOL finished){ [oldView removeFromSuperview]; }];
