I am currently using nm -ufm to get the list of imports in a library file. However, for objective-c symbols, I only seem to be getting the imported class definitions. For example, a part of the imported symbols in libGoogleAdMobAds.a are:
libGoogleAdMobAds.a(GADIdentifierUtilities.o) (for architecture i386):

Which lists a bunch of objective-c classes, but I would like to know exactly which methods are being called.
I am not very knowledgeable in the implementation details of objective-c method calls (pardon me, I meant "message passing"), but since I'm also seeing an imported _objc_msgSend, does this mean that calls are resolved at runtime by name, using some kind of reflection?
Regardless, is it possible to get a list of the actual methods used by a library?
Note: it should be possible, because Apple can. I'm investigating a rejection I had for an iOS app for using the uniqueIdentifier method of UIDevice, but doing a simple grep as suggested here is way too vague, as the string can be anything, including a string resource inside the file, and I would like to corroborate the information I got with grep with a more substantial report, like the one from nm.
