應用程序在iPhone模擬器上工作，但在真正的iPhone設備上崩潰

Question

今天我試着在我的iPhone設備上運行我的應用程序，它崩潰了！它在模擬器上工作得很好，我不知道問題是什麼。

這些崩潰日誌：

我試圖尋找錯誤，但我不知道要尋找什麼。有人可以幫助解決這個問題嗎？

Answer 1

CCSprite initWithTexture:引發異常，導致您的應用程序退出。我並不完全掌握Cocos2d，但是文檔中的快速檢查表明，它在無法找到命名文件時引發異常。

既然如此，我猜這個問題只是文件名的一種情況。 Mac默認情況下不區分大小寫。因此，如果您有FunnyImage.png，那麼如果您嘗試加載funnyimage.png，模擬器將會成功。

iOS設備區分大小寫。所以如果你嘗試加載funnyimage.png它會失敗。

因此，您可能想要做的是檢查您在代碼中使用的所有文件名是否與實際文件的大小寫完全匹配。
