TableView not deselecting properly

When I select a friend in the friend list, the row stays highlighted (gray) and no checkmark appears; however, when I select someone else in the friend list, the previous row gets the checkmark and the current row experiences the same thing (i.e. the second row stays highlighted and won't get its checkmark until I deselect it.

Here's the relevant code:

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

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

    PFRelation *friendsRelation = [self.currentUser relationForKey:@"friendsRelation"];
    PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
    [friendsRelation addObject:user];
    [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (error) {
            NSLog(@"Error %@ %@", error, [error userInfo]);
        }
    }];
}

I am having this exact same problem and created a forum post a little more than an hour before yours. I was thinking it could be something to do with the IOS/Xcode version differences but don't know for sure. Hopefully someone can help us out. https://teamtreehouse.com/forum/friends-do-not-add-or-get-removed-when-clicked

Not a problem. The more this question is out there, the more likely we get it figured out :)

-(void)tableView:(UITableView *)tableView did ->De <- "remove" ->S<- Make the" s capital" SelectRowAtIndexPath:(NSIndexPath *)indexPath {

[self.tableView deselectRowAtIndexPath:indexPath animated:NO];

You accidentally took the wrong method from the autocomplete. It must be didSelect :-)
