的Cocos2D 2 OSX EXC_BAD_ACCESS（SIGSEGV）

Question

我更新一个游戏，我有Mac和通过的XCode运行时的更新工作正常。

我试图通过开发者ID签名的应用程序一起分发，所以我可以有一个朋友测试它，当我运行应用程序，并给予他们只是它的主菜单后崩溃的应用程序。我输出它错了吗？为什么它会通过XCode运行良好，然后我尝试导出它，并且每次崩溃？

这是我的错误日志：

Answer 1

从头开始的。

在这条线盯着小时后：

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

我意识到，代码包括了一个循环，我无法弄清楚什么是错的吧！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++ { 

    } 

所以对于这么简单的东西导致崩溃的Xcode外面但是不会驱使我疯了！

感谢您的阅读！
