Below code gives permission to retrieve the logged in user’s emailID. Similar to this, is there any way you can retrieve other user’s emailID on passing facebook ID?
[[AppDelegateObj facebook] requestWithGraphPath:@”me/permissions” andDelegate:self];
No. You can only access a user’s email, if they are using your app directly and have given you permission. There is no such thing as a
friends_emailpermission.
