ios - 如何在启动时调试 iOS 应用程序崩溃，仅在程序集文件中设置断点

转载作者：塔克拉玛干更新时间：2023-11-02 09:42:15

我正面临一个与目前正在开发的应用有关的问题。问题是应用程序在后台运行一段时间后在启动时崩溃，并且仅在这种情况下。在应用程序被杀死时启动应用程序不会导致崩溃，无论是从调试器还是从手机。在后台启动应用程序大约 5-10 分钟不会导致崩溃，无论是否进行调试。在后台启动应用程序约 15-20 分钟会导致崩溃。使用调试器和异常断点给了我这个文件:

调试器在陷阱行中断，就在最后的 nop 之前:

Thread 1: EXC_BREAKPOINT (code=EXC_ARM_BREAKPOINT, subcode=0xdefe)

我找不到任何关于如何调试它的线索。

如有任何帮助，我们将不胜感激。

最佳答案

查看此错误消息。似乎 iOS SDK 中的断言检查失败。

*** Assertion failure in -[UIFetchContentInBackgroundAction sendResponse:], /SourceCache/BaseBoard/BaseBoard-97/BaseBoard/BSAction.m:221
BUG in client of libdispatch: Assertion failed: Block was run on an unexpected queue
Expected queue: 0x0x3713cd40[com.apple.main-thread]

断言确实检查了指定的 block 是否会在正确的调度队列上运行。从断言消息和堆栈跟踪中，-[UIFetchContentInBackgroundAction sendResponse:] 使用 dispatch_assert_queue检查应用程序代码是否正确使用 block 的主队列。

所以你最好检查一下你的后台获取代码应该使用主队列，但是你的代码使用的是全局队列、串行队列或并发队列。
