当我使用导航控制器推送时，如何在 UIViewcontroller 中隐藏顶部栏pushViewController ?请问有什么帮助吗?

how to hide top bar in UIViewcontroller when i push from navigation controller using pushViewController ? any help please?

推荐答案

将此代码放在要为其隐藏导航栏的视图控制器中.

Put this code in the view controller you want to hide the navigation bar for.

- (void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:animated];
}

你可能还想把它放在那里，这取决于你的需要:

And you may also want to stick this in there, depending on your needs:

- (void) viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:animated];
}
