iOS 隐藏系统tabBar及需要push两层时候tabBar的隐藏方法

1.首先说vc -> vc1 push一层界面的隐藏方法

在需要push的方法里

    self.hidesBottomBarWhenPushed = YES;
    ZHMeDetailTableViewController *mdvc = [[ZHMeDetailTableViewController alloc] init];
    [self.navigationController pushViewController:mdvc animated:YES];
    self.hidesBottomBarWhenPushed = NO;

// 注:有的时候用self.hidesBottomBarWhenPushed = YES;无效,这时要用mdvc.hidesBottomBarWhenPushed = YES;

2.需要push两层界面时隐藏tabBar的办法

即vc -> vc1 -> vc2

在vc -> vc1的写法还是要向上面一样

然后, 在vc1的 viewWillAppear 方法中

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    self.hidesBottomBarWhenPushed = YES;
}

在vc2的 viewDidDisappear 方法中

-(void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
    self.hidesBottomBarWhenPushed = NO;
}

问题完美解决
