與tabbar控制器一起使用navigationcontoller

Question

我試圖做到這一點，所以我有一個標籤欄在我的屏幕底部，它始終在那裏。我也想要它，所以如果我在其中一個選項卡中「點擊」某個菜單，它可以讓您選擇返回，從而導航控制器和標籤欄控制器。

我還是不太瞭解iOS，所以我發現的答案讓我感到困惑。

這樣的回答：Having a UITabBar AND a UINavigationController in an app?

那麼，如何實現這一點？我猜我在我的應用程序委託中更改了此方法，

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    // Override point for customization after application launch. 
    UIViewController *viewController1, *viewController2; 
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { 
     viewController1 = [[CFSDFirstViewController alloc] initWithNibName:@"CFSDFirstViewController_iPhone" bundle:nil]; 
     viewController2 = [[CFSDSecondViewController alloc] initWithNibName:@"CFSDSecondViewController_iPhone" bundle:nil]; 
    } else { 
     viewController1 = [[CFSDFirstViewController alloc] initWithNibName:@"CFSDFirstViewController_iPad" bundle:nil]; 
     viewController2 = [[CFSDSecondViewController alloc] initWithNibName:@"CFSDSecondViewController_iPad" bundle:nil]; 
    } 
    self.tabBarController = [[UITabBarController alloc] init]; 
    [self.tabBarController setDelegate:self]; 
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil]; 
    self.window.rootViewController = self.tabBarController; 
    [self.window makeKeyAndVisible]; 
    return YES; 
} 

感謝您的協助！

首先您不需要手動設置筆尖名稱。您可以將它們命名爲CFSDFirstViewController~iphone.xib和CFSDFirstViewController~ipad.xib。然後你可以撥打[[CFSDFirstViewController alloc] init]，讓iOS爲你做剩下的工作。有關信息，請參閱iOS Supports Device-Specific Resources。

關於您的問題，您只能在UITabBarController內插入UINavigationController。要做到這一點一UINavigationController類似下面的內包裝viewController1：

CFSDFirstViewController viewController1 = [[CFSDFirstViewController alloc] init]; 
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:viewController1]; 

然後用navController，而不是viewController1像folliwing

self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController, nil]; 

檢查代碼，因爲我寫的手。如果您使用非ARC項目，請注意內存。

希望它有幫助。
