如何在UINavigationController内插入UITabBarController。

目前我在应用程序委托中有main UITabBarController和prottarion（所以tab是main）

self.window.rootViewController = self.tabBarController;

在其中一个标签中，我想插入UINavigationController，但无法获取它。

代码构造如下：

MainWindow.xib 与UITabBarController对象，其中的标签键入为UINavigationController（指向NavigationHistory.xib） - 屏幕截图：无效链接
NavigationHistory.xib 仅包含UINavigationController，其中的视图指向History.xib
History.xib 只有UITableView元素 - 屏幕截图：无效链接

现在UIViewController没有显示我的View1视图，我也不知道为什么会这样。也许你有任何线索？或者指向我进行此类配置的地方。

我会自己回答。这很好解释 https://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptual/ViewControllerCatalog/Chapters/CombiningViewControllers.html

Answer 2

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;
}

Answer 3

将您的控制器对象添加到UINavigationController，并将该navigationcontroller对象添加到UITabBarController

Answer 4

UINavigationController是UIViewController的子类，UITabBarController需要一个UIViewControllers数组（因此也就是UINavigationController）;这告诉我，我可以给UITabBarController一个UINavigationControllers（或其子类）数组，给出所需的交互。

- (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;

}
