我該如何修復ViewController？

Question

我是iOS編程新手。我試圖讓已知的HelloWorld應用程序，但應用程序不起作用。所述

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); 

線程1的

部分：信號SIGABRT錯誤。

Answer 1

從堆棧跟蹤中看來，您嘗試使用方法-initWithNibName:bundle:實例化UIViewController，但使用不存在或零的nib名稱。

確保您傳入的nib名稱參數確實存在，即存在名爲ExampleViewController.xib的文件，或者該參數不爲零。

編輯---

現在你已經張貼你的代碼，我可以進一步明確。文件ViewController.xib不存在，需要創建。或者，你可能有一個錯字。將該字符串與主包中的xib（如果有）進行比較。

編輯---

既然你提到的故事板，你應該在你的-...didFinishLaunching...方法返回YES。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    return YES; 
} 

Answer 2

如果您使用故事板，那麼您不應該調用initWithNibName。這聽起來像是在試圖將來自基於XIB的應用程序的代碼混合到基於故事板的應用程序中。這是行不通的。

從你的didFinishLaunchingWithOptions方法中取出所有代碼。只需返回YES。
