ios - 在越狱的 ios 13.3 设备上生成和调试二进制文件的问题

Question

我用 Xcode 创建了一个 helloworld 应用程序并运行它。二进制安装在 /var/containers/Bundle/Application/123455-D134F-1234-3414-123123451/helloworld.app/helloworld

使用与 Cydia 一起安装的调试服务器，我可以附加到进程并调试它们，但前提是从主屏幕手动启动它们。

当我尝试生成程序并使用 lldb 对其进行调试时，发生了以下情况:lldb 成功附加，然后我发出“继续”，程序因 SIGABRT 而崩溃。

同样，我在尝试使用 frida-trace 生成它时遇到错误:进程崩溃:SIGABRT。 ...错误制定崩溃报告:优先要求符号化。相反，如果我附加到 PID，Frida-trace 工作正常。

下面是输出:

root# debugserver localhost:1111 /var/containers/Bundle/Application/123455-D134F-1234-3414-123123451/helloworld.app/helloworld

在越狱设备上调试仍然需要您先打开应用程序。您可以安装各种调整以从命令行启动应用程序，但标准程序是正常启动应用程序，然后使用 ps -ax 列出 PID，找到应用程序的 PID，然后附加
