ios - 解密 iPhone 崩溃日志

Question

我在我的 iPhone 上遇到了我自己的应用程序崩溃，并试图弄清楚发生了什么。以下是 Xcode 中崩溃日志的相关部分（抱歉格式不佳）：

异常类型：EXC_CRASH (SIGABRT) 异常代码：0x0000000000000000, 0x0000000000000000 异常说明：EXC_CORPSE_NOTIFY 由线程触发：0

应用程序特定信息：调用了 abort()

过滤的系统日志：未找到

所以我确实看到了一些错误，但它们都是非特定的，而不是指向特定的调用。

我可以从这个日志或其他地方提取更多信息来找出可能出了什么问题吗？
