crash - Cocos2D 2 OSX EXC_BAD_ACCESS(SIGSEGV)

Question

我正在更新Mac专用的游戏，并且通过XCode运行时更新正常。

我尝试通过开发人员ID签名的应用程序进行分发，这样我可以让一个 friend 对其进行测试，当我运行该应用程序时，还向他们提供该应用程序时，它会在主菜单后崩溃。我导出错误吗？为什么它可以通过XCode正常运行，然后尝试导出它，并且每次都崩溃？

这是我的错误日志:

Answer 1

刮一下。

盯着这条线几个小时后:

0   com.lasthaven.wordshufflemac    0x000000010bacc52a -[GameScene scrambleWord:] + 158 (GameScene.m:322)

我意识到该代码由一个for循环组成，我无法弄清楚它出了什么问题!所以最后我忘了在for循环开始时初始化int i。

 for(int i = 0; i < [word length]; i++ {

  }

因此，对于这么简单的事情，它导致了XCode之外的崩溃，但没有崩溃，这让我发疯了!

谢谢阅读!
