当我在iOS 7中弹出ViewController时,需要再次显示TabBar

Question

在iOS 7中,TabBar在我使用时隐藏,nextviewcontroller.hidesBottomBarWhenPushed = YES; 但是当我弹回viewcontroller时需要再次显示tabbar.
它不会回来使用nextviewcontroller.hidesBottomBarWhenPushed = NO;
任何帮助将不胜感激.

Answer 1

这解决了我的问题:

- (void)viewWillAppear:(BOOL)animated { 
    self.tabBarController.tabBar.hidden = YES; 
}
- (void)viewWillDisappear:(BOOL)animated {
    self.tabBarController.tabBar.hidden = NO; 
}

Answer 2

我找到了最简单的方法来实现UITabBar的隐藏和显示.

nextviewcontroller.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:nextviewcontroller animated:YES];
nextviewcontroller.hidesBottomBarWhenPushed = NO;

因此,在您按下视图控制器后立即设置hidesBottomBarWhenPushed = NO; 这样,当您返回查看控制器时,将显示Tabbar.
