No you won’t.  Objective-C dispatch does not work that way - methods are not 
called directly, the only symbol that you will see is objc_msgSend.

It is, however, possible to see the list of selectors that a an application 
uses, though these are not tied to classes.  It’s also possible with the git 
head of libobjc2 (or with DTrace on OS X) to track the {class,selector} pairs 
for every message send and record them as the method runs, though this is a 
static analysis.
