如何在UITabBarController中嵌入UINavigationController

Question

如何在UITabBarController中嵌入UINavigationController。

目前我有一个主UITabBarController，在应用程序代理中声明如下（因此选项卡是主要的）：

self.window.rootViewController = self.tabBarController;

我想在其中一个选项卡中插入UINavigationController，但是无法实现。

代码构造如下：

1. MainWindow.xib使用UITabBarController对象，并将选项卡类型设置为UINavigationController（指向NavigationHistory.xib）- 截图：无效链接
2. NavigationHistory.xib仅包含UINavigationController，其中视图指向History.xib
3. History.xib只有UITableView元素 - 截图：无效链接

现在UIViewController不显示我的View1视图，我不知道可能的原因。你有任何线索吗？或者指导我找到这样配置的位置。

我会回答自己。在 https://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptual/ViewControllerCatalog/Chapters/CombiningViewControllers.html 上有很好的解释。

Answer 2

将您的控制器对象添加到UINavigationController中，然后将该navigationcontroller对象添加到UITabBarController中。

Answer 3

UINavigationController是UIViewController的子类，UITabBarController期望一个包含UIViewControllers的数组（因此也包括UINavigationController）；这告诉我可以给UITabBarController提供一个UINavigationController数组（或其子类），从而实现所需的交互。

参考：https://developer.apple.com/library/ios/documentation/UIKit/Reference/UINavigationController_Class/

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tab = [[UITabBarController alloc] init];


SimpleTableViewController *tableView = [[SimpleTableViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc] initWithRootViewController:tableView];
UITabBarItem *item = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemHistory tag:0];
nav1.tabBarItem = item;


AboutViewController *about = [[AboutViewController alloc] init];
UINavigationController *nav2 = [[UINavigationController alloc] initWithRootViewController:about];
UITabBarItem *item2 = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFeatured tag:0];
nav2.tabBarItem = item2;

tab.viewControllers = @[nav1,nav2];

self.window.rootViewController = tab;
[self.window makeKeyAndVisible];
return YES;

在 appdelegate.m 文件中编写代码.....

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

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

        UIViewController *1st_View = [[FirstViewController alloc] initWithNibName:@"FirstViewController_iPhone" bundle:nil];

        UINavigationController *Navigation = [[UINavigationController alloc] initWithRootViewController:1st_View];

        [Mutablarray addObject:Navigation];

        UIViewController *2nd_View = [[SecondViewController alloc] initWithNibName:@"SecondViewController_iPhone" bundle:nil];

        UINavigationController *Navigation  = [[UINavigationController alloc] initWithRootViewController:2nd_View];
        [Mutablearray addObject:Navigation];

    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = Mutablearray;
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}
