Ios 无法更改popviewcontrolleranimation

我正在尝试更改

navigationController

推送和弹出动画，如

presentModalView

和

dismissModalView

动画

我正在使用下面的代码成功更改推送视图动画。用于更改推送动画效果良好。此代码显示从下到上的

视图

动画（用于推送视图）

但是当我尝试使用下面的代码更改pop视图动画时。我无法获得从上到下的动画（对于pop视图）

请找个人帮我。

测试代码：

CATransition *transition = [CATransition animation];
transition.duration = 0.4f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

//Pop Animation
transition.type = kCATransitionReveal;
transition.subtype = kCATransitionFromBottom;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController popViewControllerAnimated:NO];


//Push Animation
//transition.type = kCATransitionMoveIn;
//transition.subtype = kCATransitionFromTop;
//[self.navigationController.view.layer addAnimation:transition forKey:nil];
//[self.navigationController pushViewController:viewControllerToBePushed animated:NO];

你在看什么？你的第二个过渡是推送，而不是你所说的类型。嘿，哥们，我在开发示例应用程序。代码已更新，请立即验证。测试。

CATransition *transition = [CATransition animation];
transition.duration = 0.4f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController popViewControllerAnimated:NO];

CATransition *transition = [CATransition animation];
transition.duration = 0.4f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

//Pop Animation
transition.type = kCATransitionReveal;
transition.subtype = kCATransitionFromBottom;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController popViewControllerAnimated:NO];


//Push Animation
//transition.type = kCATransitionMoveIn;
//transition.subtype = kCATransitionFromTop;
//[self.navigationController.view.layer addAnimation:transition forKey:nil];
//[self.navigationController pushViewController:viewControllerToBePushed animated:NO];
