推荐答案

您可以将UINavigationController的视图添加到UIWindow，并使其遮盖第一个视图或从UIWindow中删除该视图.navigationController没有后退按钮可以将您带回到第一个视图(因为它的堆栈不包括第一个控制器)，因此，如果您想提供返回的路径，则需要一个自定义按钮.

You can add the view of the UINavigationController to the UIWindow and either let it obscure the first view or remove that view from the UIWindow. The navigationController won't have a back button to take you back to the first view (since it's stack doesn't include the first controller), so you'll need a custom button if you want to provide a way back.

- (IBAction) buttonPressed {
    myNavigationController = [[UINavigationController alloc] initWithRootViewController:mySecondViewController];
    [self.view.window addSubview:myNavigationController.view];
    [self.view removeFromSuperview];
}

这是您问题的直接答案，但是，如果您只是想要UINavigationController功能，但又不想在第一个屏幕上看到UINavigationBar，请查看:
