iOS 崩溃日志 iPad sqlite 互斥锁

Question

我如何理解应用程序在我的应用程序中的哪个位置中止。如果我在其他 iPad 上启动该应用程序，它运行良好，但仅在一台 iPad 上，我会收到以下崩溃日志:以下崩溃日志的符号是否正确？如果不正确，如何正确执行？我从邮件中获取此崩溃日志，并使用 Xcode 导入它。

问题出在哪里，谁能帮帮我吗？

谢谢

正确的符号化后，我更新了我的崩溃日志。平板电脑上的数据库有 5.5 GB 大。在syncWebdienst.cs 55中，应用程序createDataTable意味着sqlite查看表是否已更改或是新的。

您的崩溃日志没有符号化。您可能没有产生崩溃的构建的存档。

无论如何，崩溃的原因似乎是您的代码阻塞了主线程超过 10 秒，并且系统杀死了您的应用程序。
