从左/右动画presentModalViewController [英] Animate presentModalViewController from right /left

问题描述

目前我使用 [自presentModalViewController：NEWVC动画：是] 。我想present newViewcontroller左/右/上/下用一个推动作用。我试图用CATransition，但它在转型之间显示黑屏。

Currently I am using [self presentModalViewController :newVC animated:YES] .I want to present newViewcontroller from left/right/top/bottom with a push effect. I tried to use CATransition but it displays a black screen in between the transition.

推荐答案

在present：

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];

[self presentModalViewController:viewCtrl animated:NO];

在解雇：

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[self.view.window.layer addAnimation:transition forKey:nil];
[self dismissModalViewControllerAnimated:NO];
