隱藏和顯示導航欄用自來水手勢

Question

可能重複：
Hide/Show Navigation & Tool Bar on tap

這是我使用隱藏導航欄的視圖之一的空白。

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

    [super viewWillAppear:animated]; 
} 

如何點擊屏幕隱藏和顯示導航欄？

Answer 1

你想要那樣的東西嗎？

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    self.navigationController.navigationBar.translucent = YES; 
          self.wantsFullScreenLayout = YES; 

    UITapGestureRecognizer *tap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation)] autorelease]; 
    tap.numberOfTapsRequired = 1; 
    [self.view addGestureRecognizer:tap]; 
} 

- (void) hideShowNavigation 
{ 
    [self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden]; 
}
