无法更改popviewcontrolleranimated

Question

我正在尝试更改navigationController推送和弹出动画，例如presentModalView和dismissModalView动画。

我使用下面的代码成功更改了推送视图动画。对于更改推送动画工作正常。此代码从下到上显示view动画（用于推送视图）。

CATransition *transition = [CATransition animation];
transition.duration = 0.4f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromTop;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController pushViewController:locationObj animated:NO];

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

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];

请有人帮助我。

经过测试的代码：

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];
