You should watch the self destructing message app videos to help you understand it better if you havent already

Ill explain it assuming you are using parse as your backend.

you would need an action for your button. Then inside that action would be the parse calls that actually implement the follower. Im assuming you have some properties defined and set already before to simplify this a bit

- (IBAction)follow:(id)sender {

     //Create the relation
     PFRelation *followingRelation = [self.currentUser relationForKey:@"isFollowing"];
     //Add the user that the currentUser wants to follow to the relation (assuming the user he wants to follow is stored    //in self.followed user
     [followingRelation addObject:self.followedUser];
     //save the current user
     [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

        if (!error) {

            //successful save

        } else {

            NSLog(@"%@ %@", error, error.userInfo);
        }
    }];

}
