获取 LLDB 断点中的方法名称和选择器

Question

我在 lldb 中添加一个断点，如下所示：

(lldb) breakpoint set -s MyApp --func-regex .
(lldb) breakpoint command add 1
Enter your debugger command(s).  Type 'DONE' to end.
> p __PRETTY_FUNCTION__
> continue
> DONE
(lldb) process attach --name MyApp --waitfor
(lldb) continue

我的目标是打印我的应用中调用的每个方法。结果如下：

(lldb)  p __PRETTY_FUNCTION__
(const char [26]) [=11=] = "void $__lldb_expr(void *)"
(lldb)  continue
Process 96238 resuming
Command #1 'continue' continued the target.
(lldb)  p __PRETTY_FUNCTION__
(const char [47])  = "-[AppDelegate($__lldb_category) $__lldb_expr:]"
(lldb)  continue
Process 96238 resuming
Command #1 'continue' continued the target.
(lldb)  p __PRETTY_FUNCTION__
(const char [47])  = "-[AppDelegate($__lldb_category) $__lldb_expr:]"
(lldb)  continue
Process 96238 resuming
Command #1 'continue' continued the target.
(lldb)  p __PRETTY_FUNCTION__
(const char [47])  = "-[AppDelegate($__lldb_category) $__lldb_expr:]"
(lldb)  continue
Process 96238 resuming
Command #1 'continue' continued the target.
(lldb)  p __PRETTY_FUNCTION__
(const char [47])  = "-[AppDelegate($__lldb_category) $__lldb_expr:]"
(lldb)  continue

问题是如何使用方法名称及其选择器的实际值删除 $__lldb_category 和 $__lldb_expr:？

Answer 1

我会使用 lldb 命令打印此信息，例如：

(lldb) frame info
frame #0: 0x0000000100018dc7 Sketch`main(argc=1, argv=0x00007fff5fbff628) + 55 at SKTMain.m:17

我会做你想做的事。如果您想要更多或更少的信息，您还可以按照此处所述定制帧信息的输出：
