parse.com cant create a relation

" Build a Self-Destructing Message iPhone App " Im trying to program a many-to-many relation, doing it as the documentation shows (and the video here). Im trying to check friends then i hit the "back" button and it shows nothing. so i checked the the "friendRelation" column and i have no relation with any of the other user ive created. the relevant code is:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    self.currentUser = [PFUser currentUser];
    PFRelation *friendsRelation = [self.currentUser relationforKey:@"friendsRelation"];
    PFUser *otherUser = [self.allUsers objectAtIndex:indexPath.row];
    [friendsRelation addObject: otherUser];
    [self.currentUser saveInBackground];

Thanks for the help

Hi Amit,

I think this might be related to a bug in the code. In FriendsViewController and CameraViewController, I am setting friendsRelation in the viewDidLoad method. That line needs to move to viewWillAppear, however. I recorded a fix in the next project (which will be a continuation of this one).

Sorry for the confusion! Hopefully that fixes it for you. I'll add a note to that video, too.
