Is there a way to Track/trace and log all the methods, by Class and Method name, during a debug session?

Question

I am not interested in logging into frameworks or under the covers but only at my source level code upon entry and exit of each method. I would like it to provide Class Name

Answer 1

An alternative which you can use with iOS simulator on the Mac (arm/x86_64)

1. Create a Symbolic Breakpoint
2. Symbol: objc_msgSend
3. Action: Debugger Command

4. Command:

   p (void)printf("[%s, %s]\n", (char*)object_getClassName($arg1), $arg2)
   

   *p is an alias for expr --

5. Check: Automatically continue after evaluating actions

Answer 2

Dave Dribin covers precisely this in his article Tracing Objective-C messages.

The part you are after is probably this:

If you set the NSObjCMessageLoggingEnabled environment variable to YES, the Objective-C runtime will log all dispatched Objective-C messages to a file named /tmp/msgSends-<pid>.

Xtrace (https://github.com/johnno1962/Xtrace) has many features and works well for tracing Objective-C. One needs source access to their project, like you appear to have, and can emit messages on entry/exit, like you appear to want.

• Debug-time configuration - can hard-code or configure tracing while debugging
• Uncomplicated integration - one .mm and one .h
• NSRegularExpression matching - classes, methods, types
