如何在UITabBarController中插入UINavigationController

Question

如何在UITabBarController中插入UINavigationController。

目前，我有主UITabBarController裏面應用程序委託declatarion這樣的（所以標籤是主要的）

self.window.rootViewController = self.tabBarController; 

而且裏面一個選項卡，我想插入UINavigationController，並不能得到它。

的代碼池莉構建是這樣的：

1. MainWindow.xib與UITabBarController與標籤對象類型爲UINavigationController（指向NavigationHistory.xib） - 截圖：無效鏈路
2. NavigationHistory.xib僅包含UINavigationController其中查看指向History.xib
3. History.xib只有UITableView元素 - 屏幕截圖：無效鏈接

現在UIViewController不顯示我的視圖1視圖，我不知道爲什麼它可能是。也許你有任何線索？或者將我指向完成這種配置的地方。

Answer 1

我會回答我自己。這是很好的 https://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptual/ViewControllerCatalog/Chapters/CombiningViewControllers.html

Answer 2

解釋寫appdelegate.m文件中的代碼.....

- (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

控制器對象添加到UINavigationController的，並添加navigationcontroller對象的UITabBarController

Answer 4

的UINavigationController是一個UIViewController的子類，UITabBarController需要一個UIViewControllers數組（因此UINavigationController）;這告訴我，我可以給UITabBarController一個UINavigationControllers（或其子類）的數組，給出所需的交互。

- (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; 

}
