逆向工程 - (iOS lldb) 无法调试通过启动/加载屏幕 - 吾爱随笔录

我正在尝试 lldb 调试这个特定的 iOS 应用程序。

它的行为是当我单击应用程序时，会出现启动/加载屏幕，然后是主要活动。

但是，每当我尝试通过 lldb 调试应用程序时，它都会卡在启动/加载屏幕中。即使我设置了断点，它也不会停止，而是停留在屏幕上。

例如，当我通过 lldb 处理连接时，会显示：

Process 2517 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP
    frame #0: 0x000000010496d444 dyld` dyld::findMappedRange(unsigned long)  + 32
dyld`dyld::findMappedRange:
->  0x10496d444 <+32>: cbz    x8, 0x10496d460           ; <+60>

thread #1: tid = 0x1e2a0, 0x000000010496d444 'dyld`dyld::findMappedRange(unsigned long) + 32, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP

然后， I continue，但启动/加载屏幕不会处理到下一个活动。

Process 2517 resuming

所以我process interrupt停下来，lldb显示以下内容：

有谁知道为什么它没有通过启动/加载屏幕？

谢谢
