Xcode 5.沒有故事板的選項卡式應用程序？

Question

該問題類似於this one，但它是在Xcode 5不存在時創建的。而這個問題仍然沒有答案。關於如何刪除故事板也有類似的問題，但它們是關於導航控制器，而不是標籤欄控制器。

我的動作命令：

1. 創建標籤的applcation

2. 刪除所有的故事板文件

3. 從的.plist

4. 刪除故事板製作的UITabBarController的子類和編輯XIB

5. 改變應用程序委託：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Override point for customization after application launch. 
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; 
    BKTabController *navVC = [[BKTabController alloc] initWithNibName:@"BKTabController" bundle:nil]; 
    self.window.rootViewController = navVC; 
    [self.window makeKeyAndVisible]; 

    return YES; 
} 

結果是黑屏帶有灰色的地方，而不是標籤欄。

哪裏錯了嗎？

Answer 1

您看到一個黑屏，因爲您的標籤欄爲空，所以您必須將ViewController添加到您的TabController。

修改你的appdelegate這樣的：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Override point for customization after application launch. 
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; 
    BKTabController *navVC = [[BKTabController alloc] initWithNibName:@"BKTabController" bundle:nil]; 
    self.window.rootViewController = navVC; 

    FirstViewController* firstView = [[FirstViewController alloc]initWithNibName:nil bundle:nil]; 
    firstView.title = @"FIRST"; //THIS WILL BE THE TITLE OF YOUR FIRST TAB 

    SecondViewController* secondView = [[SecondViewController alloc]initWithNibName:nil bundle:nil]; 
    secondView.title = @"SECOND";//THIS WILL BE THE TITLE OF YOUR SECOND TAB 

    //ADD VIEW CONTROLLER TO YOUR TAB CONTROLLER 
    self.tabBarController.viewControllers = @[firstView,secondView]; 

    [self.window makeKeyAndVisible]; 
    return YES; 
} 

摘要：

1. 添加兩個O更多新ViewControllers到您的Xcode項目（EX FirstViewController，SecondViewController）。
2. 通過將此ViewControllers添加到您的選項卡欄控制器來修改您的應用程序委託。
