Category Conflict: instance method in category from conflicts with same method from another category

Question

There are two situations, that I am aware of, that cause the following errors:

ld: warning: instance method \'resetAudioSystem\' in category from /opentok-i         


        

Answer 1

I had this warnings because I accidentally imported the implementation file of a category instead of it's header file. So:

wrong: #import 'MyClass+MyCategory.m'

right: #import 'MyClass+MyCategory.h'
