隐藏TopBar

Question

我试过隐藏顶部导航栏的3种方法，但它没有隐藏。

viewLidAppear中的

1. 我试过

   [self.navigationController setToolbarHidden:YES];
   

2. 使用此代码

   符合UINavigationControllerDelegate

   (void)navigationController:(UINavigationController *)navigationController
                 willShowViewController:(UIViewController *)
                           viewController animated:(BOOL)animated
   {
   
   
   
   BOOL shouldHide = [viewController.toolbarItems count] == 0;
   [navigationController setToolbarHidden:shouldHide animated:animated];
   
   
   }
   

在检查器中TopbarHidden也设置为True，当我将nib加载到UIView中时......

UINavigationController *NAV_instructions = [[UINavigationController alloc] initWithRootViewController:instructions];

[NAV_instructions setToolbarHidden:YES];
[NAV_instructions setModalTransitionStyle:UIModalTransitionStylePartialCurl];

如何隐藏到顶部栏？

Answer 1

试试这个：

self.navigationController.navigationBarHidden = YES;
