You'll get better advice if you expand upon what you want
& why; what is the real problem you are trying to solve
here?<br>
<br>
If, for example you're simply wanting to programatically
find all senders of a particular message then the code is
already there -<br>
take a look at
SystemNavigation>allCallsOn:fromBehaviors:sorted: to see
how to scan all the methods implemented by a list of
behaviours (ie classes or metaclasses) for sends of a
particular message, including ones that are special cases.<br>
If you already know which class and method you want to look
at then examine
Behavior>whichSelectorsReferTo:specialByte:thorough: to
see how the system does it.<br>
<br>
Or are you wanting to look for particular fragments of code
with some sort of text based pattern matching? Or…?<br>
