更改动画UINavigationController的导航栏 [英] Changing the animation for UINavigationController NavigationBar

问题描述

现在，当我使用[self.navigationController setNavigationBarHidden：无动画：是];

Right now when I use [self.navigationController setNavigationBarHidden:NO animated:YES];

导航栏苍蝇从右到左，是有办法顶砸下来到底？

The navigation bar flies in from right to left, is there a way to drop it down top to bottom?

推荐答案

给这个一展身手：

CATransition *transition = [CATransition animation];
transition.duration = kAnimationDuration;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromTop;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];

self.navigationController.navigationBarHidden = NO;
[self.navigationController pushViewController:tableViewController animated:YES];

我伟大的工作。
