使用此功能

- (void) hideTabBar:(UITabBarController *) tabbarcontroller 
{ 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDuration:0.5]; 
     for(UIView *view in tabbarcontroller.view.subviews) 
     { 
      if([view isKindOfClass:[UITabBar class]]) 
      { 
       [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)]; 
      } 
      else 
      { 
       [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)]; 
      } 

     } 

     [UIView commitAnimations]; 

} 

当你的时候，你要显示的调用这个函数

[self hideTabBar:self. tabbarcontroller]; 

tabbarcontroller使用此功能

- (void) showTabBar:(UITabBarController *) tabbarcontroller { 

        [UIView beginAnimations:nil context:NULL]; 
        [UIView setAnimationDuration:0.5]; 
        for(UIView *view in tabbarcontroller.view.subviews) 
        { 
            NSLog(@"%@", view); 

            if([view isKindOfClass:[UITabBar class]]) 
            { 
                [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)]; 

        } 
        else 
        { 
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)]; 
        } 


    } 

    [UIView commitAnimations]; 
}
