There's an interesting little article called Building a better otool
that builds up a script that uses otool and basically does all the
lookups for you and inserts comments telling you what the selectors
are.

I am wonder if anyone knows of good tricks to use to relatively
quickly understand what selector is being used in a call to
objc_msgSend. For example given the following otool -toV output how
can I figure out what selector is being used?
I assume the 0xfd4 is an memory offset to a table selectors, and
0x9c68 is an offset to the selector in question. Just missing out of
the expected location of that table and how to view it via otool.
930b4b24 addis r4,r31,0xfd4
930b4b28 or r5,r3,r3
930b4b2c lwz r4,0x9c68(r4)
930b4b30 or r3,r25,r25
930b4b34 bl 0x931f1208 ; symbol stub for: _objc_msgSend
