ios 应用程序在测试时工作但在发布后崩溃

Question

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。但是今天发布后它立即崩溃了。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)

但是!适用于:-iPhone 4 (iOS 5.0) ?!?

因为它在从 xcode 启动时有效，我们无法重现此错误，有什么想法吗？

这是崩溃日志的片段，您需要更多详细信息吗？

谢谢!

您似乎在 viewDidLoad 中调用了 CDVViewController 无法处理的方法。最好在该方法中检查发送到该类实例的所有消息(很可能是 self.property 或 [self something])。
