What would you like to do?
Set symbol breakpoint on objc_msgSend then setup this debug command to log all methods called in iOS Simulator. If you want to do device debugging change esp+4 register to r0, esp+8 to r1 Found long ago somewhere on stackoverflow.
expr -- (void)printf("[%s, %s]\n",(char *) object_getClassName(*(long*)($esp+4)), (char *) *(long *)($esp+8) )

And if you need more control, Xtrace will let you trace Objective-C calls by class or instance, indented and optionally colored.

@midorikocak

how can I limit output to my class methods only?
