Use of undeclared identifier 'isFriend' error when It's clearly defined.

In my EditFriendsViewController.h:

- (BOOL)isFriend:(PFUser *)user;

In my EditFriendsViewController.m:

- (BOOL)isFriend:(PFUser *)user {

}

Error is "Use of undeclared identifier 'isFriend'"

Doing the same thing that he does in the video, yet getting this error...

you are defining a method inside of your didSelectRowAtIndexPath method. You cant do that. Move the definition out of that method and see if you still get that error. so you should have something like

- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Makes the row not highlighted after clicking on it.
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];

    //The cell's accessory type is a checkmark.
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

    //Friends relation = key friendsRelation.
    PFRelation *friendsRelation = [self.currentUser relationForKey:@"friendsRelation"];
    PFUser *user = [self.allUsers objectAtIndex:indexPath.row];

    //When a user is clicked on, add them as a friend.
    [friendsRelation addObject:user];

    //Save.
    [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (error) {
            NSLog(@"Error %@ %@", error, [error userInfo]);
        }
    }];

}

- (BOOL)isFriend:(PFUser *)user {   //Error here!

}

are you calling that method anywhere? what line of code is giving you the use of undeclared identifier error?
