问题描述

此代码在 iOS 7 发布之前运行良好.我正在分配一个 UIViewController，其中 hidesBottomBarWhenPushed 作为 YES，作为 UINavigationController<的 rootViewController/代码>.但是 TabBar 无论如何都会显示出来.以下是相关代码:


This code was working well until iOS 7 release. I'm assigning a UIViewController, with hidesBottomBarWhenPushed as YES, as the rootViewController of an UINavigationController. But the TabBar is being shown anyway. Here's the relevant code: 
Login *lv = [[Login alloc] init];
lv.HowToUseShows = showHowToUse;
lv.hidesBottomBarWhenPushed = YES;

UINavigationController *BokShelfNav = [[UINavigationController alloc] initWithRootViewController:lv];

//... 

UITabBarController *tbController = [[UITabBarController alloc] init];
tbController.viewControllers = @[BokShelfNav,...];

有类似问题的人吗?
推荐答案
我发现调用方法和设置属性的顺序对标签栏是否显示有影响.
I found that the order in which methods are called and properties are set has an impact on whether the tab bar is shown.
如果我将 self.hidesBottomBarWhenPushed = YES; 放在视图控制器的 viewDidLoad 方法中，我正在推动的标签栏仍然显示.如果我将它移到 init 方法，标签栏会像在 iOS 6 上一样隐藏.
If I put self.hidesBottomBarWhenPushed = YES; in the viewDidLoad method of the view controller I'm pushing the tab bar still shows. If I moved it to the init method the tab bar hides as it used to on iOS 6.
