我的iPhone应用程序因英国某些用户而崩溃。我尝试使用英国时区及其区域格式，但无法在我的iPhone或模拟器上重现崩溃。最终得到了一份崩溃报告，我能够象征它。但是，我很难理解结果。看起来线程0在系统库中崩溃了。我的应用程序中唯一的电话是main.m.
线程4有一些熟悉的东西。它在：
My App 0x00004cca -[TocTableController parser:didEndElement:namespaceURI:qualifiedName:] (TocTableController.m:1369)
代码是：
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
它崩溃了做alloc / init吗？内存不足，只在英国？任何人都知道可能是什么原因？提前谢谢！

答案 0 :(得分：1)
崩溃的线程正在运行主事件循环。发生的事情之一是自动释放池被耗尽，因此这可能是对象被过度释放的问题。
如果你可以重现这个问题，打开NSZombieEnabled将是一个很好的方法来追踪任何过度释放错误，但这不是你可以在运输应用程序上启用的。
答案 1 :(得分：0)
相信我仍然如此。你有过度释放的对象。只需使用NSZombies即可找到管理不当的确切对象。
