I am currently trying to learn how to build apps. I've used C in an embedded control course at college and I'm going back to learn it better, learn C++, then objective C.
One of the first apps I want to build involves implementing facebook. It takes the user's facebook info and gets a list of their friends (which from other apps seems to be no problem).
The problem is, is that I want to get information regarding the mutual friends between the user and their friend. If the user accepts privacy settings, can this information be obtained? Or is this not allowed because approval would also be needed from the friend?
Thanks.
