NavigationController 中的 TabBarController [英] TabBarController inside NavigationController

问题描述

想象一下，我们有一个由导航控制器控制的多视图应用程序.我们使用 pushViewController 方法从第一个视图转到第二个视图，这不是问题，但是我们需要移动到第三个视图.第三个是一个看起来像 TabBar 的视图.我们怎么做?第三个视图应该是由 TabBarController 控制的，不是吗?那么如何传递控制呢?我声明了一个插座 UITabBarController * tbc 并将其连接到 xib 文件中的 TabBarController 然后我在 viewDidLoad 中尝试了这个:tbc = [[UITabBarController alloc]init];

Imagine that we have multiview apllication which is controlled by Navigation Controller. We go from the first view to second by using pushViewController method and that's not a problem but then we need to move to the third view. And the third one is a view which looks like a TabBar. How do we do that? The third view is supposed to be controlled by TabBarController, isn't it? So how to pass the control? I declared an outlet UITabBarController * tbc and connected it to TabBarController in xib file and then i tried this in viewDidLoad: tbc = [[UITabBarController alloc]init];

它什么也没显示.非常感谢您的帮助

and it shows nothing. Your help is highly appreciated

推荐答案

有点奇怪.使用 tabBarController 切换视图更标准，其中一些视图可能是导航控制器.但是……

It's a bit wierd. Its more standard to have a tabBarController that switches views and some of those views may be navigation controllers. But ...

创建 UITabBarController 并推送它.

Create the UITabBarController and push it.

NSMutableArray *viewControllers = [[NSMutableArray alloc] init];

// create someView
[viewControllers addObject:someView];
// create someView2
[viewControllers addObject:someView2];


UITabBarController *tabController = [[UITabBarController alloc] init];
[tabController setViewControllers:viewControllers];

[[self navigationController] pushViewController:tabController animated:YES];

然后，从tabBarContoller视图，根据一些动作，你可以选择弹出它:

Then, from the tabBarContoller view, based on some action, you can choose to pop it:

[self.navigationController popViewControllerAnimated: NO];
