哇。让我刚刚摆脱我的水晶球，并从中导出导致这次崩溃的代码。 – Fogmeister

我希望有模式中的某些东西可以提供线索。在调试时我无法找到重现错误的方法。 –

尝试启用断点都看到下面

enter image description here

这样，你应该能够SIGABRT信号之前识别坏的指令。

我希望这能帮助

是的，我想，但还没有找到重现崩溃的方法。所以偶尔会发生，但从来没有附加调试器。我希望报告中有某些东西可以确定一个可能的原因，我可以试着重新尝试重现错误。 –

你在使用UIWebView吗？在这种情况下，当尝试加载某些内容时，可能会导致应用程序崩溃，特别是内部使用大量JavaScript代码的PDF文档或复杂页面。这个问题通过iOS更新得到解决，但仍然存在 –

是的，我喜欢。应用程序同步，然后（在后台，但自然在主UIThread）加载内容来计算所需的高度，以便稍后在UITableViewCell中显示文章并缓存任何图像以加快加载速度。也许我应该朝那个方向看。 –
