Ios---隐藏tabbar

转载自：http://blog.sina.com.cn/s/blog_8988732e0100zwn9.html

隐藏tabar的时候，有两种方法，一种是在压栈前，设置 hidesBottomBarWhenPushed 为 YES

   

   另一种是用代码实现效果

   - (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];

    [self hideTabBar:YES];//隐藏tabbar

}

- (void)viewWillDisappear:(BOOL)animated {

    [super viewWillDisappear:animated];

    [self hideTabBar:NO];//显示tabbar

}

实现方法如下：

 

- (void) hideTabBar:(BOOL) hidden {

    

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0];

    

    for(UIView *view in self.tabBarController.view.subviews)

    {

        if([view isKindOfClass:[UITabBar class]])

        {

            if (hidden) {

                [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];

            } else {

                [view setFrame:CGRectMake(view.frame.origin.x, 480-49, 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, 480)];

            } else {

                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480-49)];

            }

        }

    }

    [UIView commitAnimations];

}

其中 480 根据情况设置，我这里连  UINavigationBar  也隐藏了
