點擊時隱藏導航欄

Question

我在我的應用程序中製作幻燈片。我希望它幾乎像蘋果的照片應用程序。幾乎完成了一些小問題。我想在屏幕上點擊時隱藏導航欄，然後再次點擊時顯示。但我不知道如何做到這一點。

Answer 1

// catch the screen tap and call a method to hide the navigation bar 
UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(toggleNavBar:)]; 
[self.view addGestureRecognizer:gesture]; 
[gesture release]; 

- (void)toggleNavBar:(UITapGestureRecognizer *)gesture { 
    BOOL barsHidden = self.navigationController.navigationBar.hidden; 
    [self.navigationController setNavigationBarHidden:!barsHidden animated:YES]; 
} 

Answer 2

你想如何隱藏導航欄？點擊在導航欄（這將是非常棘手的，如果不是徹頭徹尾的不可能）或通過其他按鈕或通過其他方法？

一般來說，你肯定可以隱藏導航欄。

看[UINavigationController setNavigationBarHidden: animated:]（我已經聯繫了蘋果文檔）

Answer 3

1. 添加手勢使用

UITapGestureRecognizer * theSingleTapGesture = [[UITapGestureRecognizer頁頭] initWithTarget到屏幕：自

action：@selector（handleSingleTapForImage :)]; [inImageView addGestureRecognizer：theSingleTapGesture]; [theSingleTapGesture發佈];

1. 手勢的方法顯示或隱藏導航欄

   -(void)handleSingleTapForImage:(UITapGestureRecognizer *)sender { 
   [self.navigationController setNavigationBarHidden:![self.navigationController isNavigationBarHidden] animated:YES]; 
   

   }

使導航半透明

self.navigationController.navigationBar.barStyle=UIBarStyleBlackTranslucent;
