我们刚刚发布了一款使用xcode 4.5.2，cordova-2.2.0的新iPhone应用程序 测试时一切正常。但在今天发布后，它立即崩溃。开始屏幕闪烁一秒钟，然后崩溃。
崩溃： -iPhone 5（iOs 6.0.1） -iPhone 4s（iOs 6.0.1） -iPhone 4（iOs 6.0.1）
BUT！适用于： -iPhone 4（iOs 5.0）？！？
因为它从xcode开始工作时我们无法重现这个错误，有什么想法吗？
这是崩溃日志的一个片段，您需要更多详细信息吗？
谢谢！

似乎你在viewDidLoad中调用CDVViewController无法处理的方法。最好检查您在该方法中发送给该类实例的所有消息（很可能是self.property或[self something]）。
答案 1 :(得分：0)
确保归档并运行应用程序
当您在调试模式下运行它时，您将得到不同的编译，因此可能会有不同的结果。 （调试模式=从XCode中单击运行时运行）
另外，我感觉你在iOS 6中使用了一种不推荐使用的方法。（你明显得到一个'未定义的选择器'错误，它提示你访问一个你不应该访问的方法）检查一下您使用的方法在iOS 6中可用。
此外，请确保您没有访问ivars。据我所知，iOS 6禁用访问私人ivars。
