隐藏tabbar

隐藏tabbar有两种方式：

1：在pushViewController之前调用

[self setHidesBottomBarWhenPushed:YES];

同时在viewWillDisappear调用：

- (void)viewWillDisappear:(BOOL)animated {
    [self setHidesBottomBarWhenPushed:NO];
    [super viewDidDisappear:animated];
}

 

2：使用函数：

- (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, 433, 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, 433)];
            }
        }
    }
    [UIView commitAnimations];
}

方式一的方法代码简单，且界面也好控制一些
