Crash when [self performSegueWithIdentifier：@「login_success」sender：self];

我正在登錄應用程序，請按照http://dipinkrishna.com/blog/2013/12/ios-login-screen-tutorial-xcode-5-ios-7-storyboard-json/。Crash when [self performSegueWithIdentifier：@「login_success」sender：self];

當我在iPhone上測試APP時。一切都很好。

但是，當我在iPad上測試應用程序崩潰時

[self performSegueWithIdentifier:@"login_success" sender:self];

這裏是崩潰日誌：

在這裏也didFinishLaunchingWithOptions在AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

這裏是我Main_iPad.storyboard：

這裏是我Main_iPhone.storyboard：

uploadpie.com/gmpms

誰能幫我？

謝謝！

UPDATE

如果我改變模式在故事板推動下，APP依然崩潰，但它是一個不同的日誌：

的[應用錯誤試圖把模態拆分視圖控制器]可能重複（http://stackoverflow.com/questions/11843991/error-on-application-tried-to-present-a -split-view-controllers-modally） –

檢查這也http://stackoverflow.com/q/2579861/468724 –

@dasdom我已更新到問題的完整代碼。謝謝 – Arefly

你SEGUE是模態。改變其模式推動或更合適的。

我試圖改變它推送並添加ID到它。但它仍然崩潰 – Arefly

請參閱問題更新 – Arefly

現在您沒有導航控制器。推僅適用於導航控制器。 –

改變你用來從「Modal」推送到「Push」的StoryBoard segue的風格。

我嘗試將其更改爲推送並向其添加標識符login_success。但它仍然崩潰 – Arefly

請參閱問題更新 – Arefly

您應該有一個導航控制器來推動視圖控制器，所以添加一個導航控制器在故事板的開始處，並使其rootViewController成爲您想要加載的第一個視圖控制器。你可以在故事板本身做到這一點。 – ratnesh

我得到了類似的問題，並掙扎了一段時間。

事實證明，我不小心從Copy Bundle Resources中刪除了「Main.storyboard」文件。

爲了以防萬一，請確保您的「Main.storyboard」文件位於軟件包列表中。
