iPhone - presentModalViewController从右侧过渡 [英] iPhone - presentModalViewController with transition from right

问题描述

我正在使用presentModalView控制器并通过其控制器将转换推送到新视图。
我正在使用以下代码进行转换（工作正常）

I'm using presentModalView controller and pushing the transition to new view via its controller. And I'm using following code to do the transition (which is working fine)

    [self presentModalViewController:myViewController animated:NO];
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[myViewController.view layer] addAnimation:animation forKey:@"SwitchToView"];  

但问题是，它显示空白屏幕然后转换开始。如何避免这种情况？

but the problem is that, its showing blank white screen and then transition starts. How to avoid this?

推荐答案

首先添加动画然后出现

CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[myViewController.view layer] addAnimation:animation forKey:@"SwitchToView"];  


[self presentModalViewController:myViewController animated:NO];
