PFRelation create with UiButton on Cell

Hello everyone ... I'm trying to create PFRelation using a button in a TableView with custom cell, but I can not create these relationships, I only creates a relationship with a specific user regardless of the cell that I select. ..

Where am I doing wrong?

       - (IBAction)FFAddAmiciAction:(id)sender {
             NSIndexPath *indexPath = [[self tableView] indexPathForSelectedRow];
            PFObject *searchedUser = [self.objects objectAtIndex:indexPath.row];
            PFUser *user = [PFUser currentUser  ];
             PFRelation *relation = [user relationforKey:@"Amic"];
               [relation addObject:searchedUser];
                 [user saveInBackground];

}

Set breakpoints to see if a row is being selected and which user you are getting back in searchedUser variable

Amit Hello and thanks for the reply ... In the end I managed to find the problem for the button ... was enough to set the action as [sender tag] and everything worked ...

I was following the tutorial on your friends list and show what friends are and what they are not friends through the checkmark ... Surely it is not my fault but I can not get it to work ...

In my tableviewController I also implemented the Search Bar could be the problem?? Could you help me understand with a practical example ... are two days that I try but I just can not understand how I can implement your tutorial within my viewcontroller with searchbar
