如何隐藏uitabbarcontroller [英] How to hide uitabbarcontroller

问题描述

我遇到了 UITabBarController 的问题。在我的应用程序中，我想隐藏它但不使用 hidesBottomBarWhenPushed 因为我想要隐藏它而不是在我推动它时。例如，我想在我的应用程序中按隐藏按钮时隐藏它。

I have a problem with UITabBarController. In my application, I want to hide it but without using hidesBottomBarWhenPushed because I want to hide it not when I pushed it. For Example, I want to hide it when I press a Hide button in my application.

我在谷歌阅读了很多文章，但我无法知道如何做到这一点。

I read many articles in google but I cant find out how I can do this.

推荐答案

我从我的工作代码中粘贴这个...你可以调用这些方法来隐藏和显示tabbarcontroller ......只需将tabbarcontroller实例传递给这些函数..

I am pasting this from my working code... you can call these methods to hide and show the tabbarcontroller.... just pass tabbarcontroller instance to these functions..

// Method call
[self hideTabBar:self.tabBarController];

// Method implementations
- (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];   
}

- (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]; 
}
