無法理解我的代碼中沒有相關方法的崩潰報告

[英]Having trouble understanding a crash report with no related methods from my code

 原文  2014-04-09 07:24:35  6   1    ios/ crash-reports/ afnetworking-2/ cfnetwork

問題描述

看起來它與網絡線程有關，大多數其他線程都處於“mach_msg_trap”狀態。 列表中的第4個線程是崩潰的線程。 我在iOS 7.1上使用AFNetworking

我感謝任何可能有助於我調查此問題的想法或想法。

您似乎需要調查這些函數的調用： mach_msg_trap和semaphore_wait_trap 。 這是崩潰的主要原因。 有時在堆棧頂部調用這些方法是接收死鎖的指標。 這里有一些調查鏈接：

嘗試通過啟動應用程序，打開URL連接，將應用程序發送到后台，等待幾秒鍾然后將其帶到前台來重現崩潰。
