如何在基于TabBar的iPhone应用程序上隐藏NavigationController？

Question

I'm building a TabBar based iPhone app. I'm using xcode 4 and I add Navigation Controller as one of the item. It allows me to disable the Navigation Bar on the startup. I basically uncheck the Shows Navigation Bar .

Navigation Bar does not show on the start up. But once I navigate to the detail view and come back Navigation Bar is showing again. Please help where can I disable the Navigation bar?

Update

Guys I'm using tabBar based app and for some reason it never get into the ViewDidLoad or viewWillAppear.

Answer 1

In your viewWillAppear method of the view controller set [self.navigationController setNavigationBarHidden:YES]; Everytime your viewController calls viewWillAppear it will setNavigationBar to hidden

Answer 2

Try:

- (void)viewDidLoad 
{
   [super viewDidLoad];

   self.navigationController.navigationBarHidden = YES;
}

Answer 3

将以下代码放在didFinishLaunching方法中的应用程序委托类中：

self.navigationController.navigationBarHidden = YES;
