问题描述

有时我的 iPhone 应用程序崩溃并显示一个奇怪的崩溃日志,读取异常代码为 0x8badf00d.堆栈跟踪显示应用程序执行的随机快照,但没有任何可疑之处.这种情况很少发生,我无法找到如何重现它.有没有人更了解这种异常和异常代码?

Sometimes my iPhone application crashes with a weird crashlog, that reads exception code is 0x8badf00d. The stacktraces show random snapshots of app execution, but nothing suspicious. This happens very rarely and I'm not able to find out how to reproduce it. Does anybody know more about this kind of exception and exception code?

这是我的崩溃日志的摘录:

推荐答案

0x8badf00d 是当应用程序启动或终止时间过长时看门狗引发的错误代码.请参阅 Apple 的iPhone 操作系统应用程序崩溃报告 文档

0x8badf00d is the error code that the watchdog raises when an application takes too long to launch or terminate. See Apple's Crash Reporting for iPhone OS Applications document
