我遇到了一个iPhone应用程序在选择少数用户启动时崩溃的问题。大多数用户都很好 - 应用程序在应用程序商店中运行，Apple没有发现任何问题，测试时从未发现这些问题。但是，它们存在。iPhone SIGABRT崩溃0x00000000：帮我多选
所以。这是我所知道的。我相信iPod touch用户会遇到这种情况。从崩溃日志我已经从一个用户得到了，我知道了异常代码：
Exception Codes: 0x00000000, 0x00000000
我相信这表明我的应用程序试图写入到内存中的零指针？ （大部分完整的崩溃日志下面）。所以，我对可能发生的事情有一些想法，我希望有人能够提供帮助...我有一些理论 - 我希望有更多的想法。麻烦的是，我很难调试，因为我没有遇到任何我的测试设备（iPhone4，iPhone3G，iPodTouch，iPad）的问题... ...
理论1）我定义了几个整数在viewDidLoad中，然后在viewWillAppear中使用它们。我知道愚蠢，但是我认为操作的顺序是viewDidLoad，viewWillAppear，然后是viewDidAppear。情况总是如此吗？我从appDelegate加载这个viewController，如果有帮助... ...
Theory2）我在viewController中创建一个UIViews数组。这些视图是IBOutlets。目前，我在viewDidLoad委托方法中创建了这个数组。这些还不存在吗？如果我等到viewWill或viewDid出现，是否可以解决这个问题？
Theory3）在应用程序中，我有一个自定义委托，它在nib文件中声明自己。它可以在它准备好之前将消息发送给视图控制器吗？
理论4）它与版本最小iOs部署目标有关。目前，我正在对4.1进行构建，但我的开发目标设置为3.1。我不相信我正在使用不存在的方法，但是这可能是根源吗？
任何这些信任？其他人面临类似的问题？非常感谢您的帮助。下面是完整的，或多或少，崩溃报告：

非常感谢迄今为止的答案 - 我会考虑这两个。另外一个信息：提交此崩溃报告的用户告诉我，在他恢复了他的ipodtouch（他一直有其他问题）后，我的应用运行良好。不过，还有其他用户遇到过崩溃。这个恢复修复是否能够让我们更深入地了解潜在的问题？ – 2010-11-14 22:19:06
嘿，你有没有发现问题是什么？我陷入了类似的局面 – alemangui 2013-02-19 13:57:47
