iOS隱藏iOS 6 + 7中的狀態欄和標籤欄

Question

我有一個標籤式應用程序，在一個標籤中有一個UIWebView。當我將設備旋轉到橫向時，我想將此UIWebView全屏顯示在狀態欄和選項卡欄上。

好了，現在我已經得到了它在iOS 6中的工作 - 原本旋轉和隱藏的標籤欄會留下一個黑色的空間，標籤欄是時候，所以fHeight代碼修復這個。然而，在iOS 6上它完美運行，但現在它實際上創建了iOS 6的黑條問題！任何想法解決這個問題？

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration; 
{ 
    if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { 
     [self hideTabBar:self.tabBarController]; 
     [[UIApplication sharedApplication] setStatusBarHidden:TRUE withAnimation:UIStatusBarAnimationSlide]; 
    } 
    else 
    { 
     [self showTabBar:self.tabBarController]; 
     [[UIApplication sharedApplication] setStatusBarHidden:FALSE withAnimation:UIStatusBarAnimationSlide]; 
    } 
} 

- (void) hideTabBar:(UITabBarController *) tabbarcontroller 
{ 
    CGRect screenRect = [[UIScreen mainScreen] bounds]; 

    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:0.5]; 
    float fHeight = screenRect.size.height; 
    if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) 
    { 
     fHeight = screenRect.size.width; 
    } 

    for(UIView *view in self.tabBarController.view.subviews) 
    { 
     if([view isKindOfClass:[UITabBar class]]) 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)]; 
     } 
     else 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; 
      view.backgroundColor = [UIColor blackColor]; 
     } 
    } 
    [UIView commitAnimations]; 
} 

- (void) showTabBar:(UITabBarController *) tabbarcontroller 
{ 
    CGRect screenRect = [[UIScreen mainScreen] bounds]; 
    float fHeight = screenRect.size.height - 49.0; 

    if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) 
    { 
     fHeight = screenRect.size.width - 49.0; 
    }

我已經使用這個嘗試，但我不知道我需要傳遞什麼看法？它應該適用於iOS 6和7

- (void)setTabBarHidden:(BOOL)hidden view:(UIView *)view animated:(BOOL)animated 
{ 
    if (self.tabBar.hidden == hidden) 
     return; 

    CGRect screenRect = [[UIScreen mainScreen] bounds]; 
    float height = 0.0f; 

    if(UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) 
    { 
     height = screenRect.size.width; 
    } 
    else 
    { 
     height = screenRect.size.height; 
    } 

    if (!hidden) 
    { 
     height -= CGRectGetHeight(self.tabBar.frame); 
    } 

    void (^workerBlock)() = ^() { 

     self.tabBar.frame = CGRectMake(CGRectGetMinX(self.tabBar.frame), height, CGRectGetWidth(self.tabBar.frame), CGRectGetHeight(self.tabBar.frame)); 
     view.frame = CGRectMake(CGRectGetMinX(view.frame), CGRectGetMinY(view.frame), CGRectGetWidth(view.frame), height); 
    }; 

    void (^completionBlock)(BOOL finished) = ^(BOOL finished) { 
     self.tabBar.hidden = hidden; 
    }; 

    if (animated) 
    { 
     [UIView animateWithDuration:0.25f animations:workerBlock completion:completionBlock]; 
    } 
    else 
    { 
     workerBlock(); 
     completionBlock(YES); 
    } 
} 

Answer 1

是的，使用適當的UIViewController旋轉方法。隱藏標籤欄控制器很容易，但iOS 7上的狀態欄更加困難。研究如何做到這一點，您應該沒問題。

Answer 2

嘗試...

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

-(void)viewWillDisappear:(BOOL)animated 
{ 
    [self.navigationController setNavigationBarHidden:NO animated:animated]; 
    [self setHidesBottomBarWhenPushed:NO]; 
    [super viewWillDisapper:animated]; 
} 

Answer 3

我得到這個工作前一段時間，忘了後我答案，因爲我有兩個類似的問題去！適用於iOS 6和7

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { 

    BOOL toLandscape = UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation); 

    CGRect screenRect = [[UIScreen mainScreen] bounds]; 

    void (^workerBlock)() = ^() { 


     [[UIApplication sharedApplication] setStatusBarHidden:toLandscape withAnimation:UIStatusBarAnimationSlide]; 

     float height = toLandscape ? screenRect.size.width : screenRect.size.height - CGRectGetHeight(self.tabBarController.tabBar.frame); 

     float width = toLandscape ? screenRect.size.height : screenRect.size.width; 

     webView.frame = CGRectMake(CGRectGetMinX(webView.frame), 
           CGRectGetMinY(webView.frame), 
           width, 
           height); 

     [self moveTabBarToPosition:height]; 
    }; 

    [UIView animateWithDuration:0.25f animations:workerBlock]; 
} 
//Moving the tab bar and its subviews offscreen so that top is at position y 
-(void)moveTabBarToPosition:(int)y { 
    self.tabBarController.tabBar.frame = CGRectMake(self.tabBarController.tabBar.frame.origin.x, y, self.tabBarController.tabBar.frame.size.width, self.tabBarController.tabBar.frame.size.height); 

    for(UIView *view in self.tabBarController.view.subviews) { 
     if ([view isKindOfClass:[UITabBar class]]) { 
      [view setFrame:CGRectMake(view.frame.origin.x, y, view.frame.size.width, view.frame.size.height)]; 
     } else { 
      [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, y)]; 
      view.backgroundColor = [UIColor blackColor]; 
     } 
    } 
} 

在我的情況下，這是我的web視圖，但理論上你可以給它任何視圖。適用於iOS 6和7
