Ios 如何在UITabBarController中插入UINavigationController

如何将

UINavigationController

插入

uitabarcontroller

内部

目前，我有main

UITabBarController

，在应用程序委托中有declatarion，如下所示（所以tab是main）

在其中一个选项卡中，我想插入

UINavigationController

，但无法获取它

代码的结构如下所示：

main window.xib

带有

UITabBarController

对象，选项卡类型为

UINavigationController

（指向

NavigationHistory.xib

）-屏幕截图：无效链接

NavigationHistory.xib

仅包含视图指向History.xib的

UINavigationController

History.xib

只有

UITableView

元素-屏幕截图：无效链接

现在，

UIViewController

不显示我的View1视图，我也不知道为什么会这样。也许你有什么线索？或者给我指出进行这种配置的地方。

我自己回答。这是很好的解释

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;
}

将控制器对象添加到UINavigationController，并将导航控制器对象添加到UINavigationController

UINavigationController是UIViewController的子类，UINavigationController需要一个UIViewController数组（因此UINavigationController）；这告诉我，我可以为UITabBarController提供一个UINavigationController数组（或其子类），以提供所需的交互

仅仅半年后，该链接就已经无效。iOS的发展肯定很快！
