在IOS中如何在特定的UIViewController中添加UITabBarController

Question

我想在我的項目中添加一個標籤欄。假設我有六個視圖控制器。現在我試圖添加標籤欄只有視圖控制器的第三個數字。我怎樣才能做到這一點？我試圖做到這一點。我在app delegate.m中添加了代碼，但是在應用程序委託中編寫代碼後，效果進入所有視圖控制器。

將這個代碼在自定義的UITabBarController

-(void)setTabBarHidden:(BOOL)hidden { 
CGRect screenRect = [[UIScreen mainScreen] bounds]; 
float fHeight = screenRect.size.height; 
if(UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)){ 
    fHeight = screenRect.size.width; 
} 
if(!hidden) fHeight -= self.tabBar.frame.size.height; 

[UIView animateWithDuration:0.25 animations:^{ 
    for(UIView *view in self.view.subviews){ 
     if([view isKindOfClass:[UITabBar class]]){ 
      [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)]; 
     }else{ 
      if(hidden) { 
       [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; 
      } 
     } 
    } 
}completion:^(BOOL finished){ 
    if(!hidden){ 
     [UIView animateWithDuration:0.25 animations:^{ 
      for(UIView *view in self.view.subviews) 
      { 
       if(![view isKindOfClass:[UITabBar class]]) { 
        if (!hidden) { 
         [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; 
         for(UIView *view in self.view.subviews){ 
          if([view isKindOfClass:[UITabBar class]]){ 
           [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)]; 
          }else{ 
           if(hidden) { 
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; 
           } 
          } 
         } 
        } 
       } 
      } 
     }]; 
    } 
}];} 

在的UITabBarController

的這種委託方法

- (BOOL)tabBarController:(UITabBarController*)tabBarController shouldSelectViewController:(UIViewController*)viewController 

你可以做一個請檢查是否顯示或隱藏的TabBar根據其的viewController是
