我有一个tabbar控制器。我想在视图中隐藏标签栏,并希望在下一个视图中取消隐藏相同的标签栏。隐藏代码适用于第一个视图,但在第二个视图中,我取消隐藏标签栏它不起作用.. < / p>
我的代码:
隐藏:
[[self navigationController] setHidesBottomBarWhenPushed:YES];
取消隐藏:
[[self navigationController] setHidesBottomBarWhenPushed:NO];

//u can call like this
//[self hideTabBarOfThisTabbarController:self.tabBarCon withAnimationDuration:3];
//if u want immediately hide/show the tabbar then duration should be 0.0
