4,354 PointsFriends List Not Updating Dynamically
I finished the "Relating Users in Parse.com" section of this project. I see the result that Ben displays in the app at the end of the last video. As I check and uncheck table view cells, the data browser in the backend updates accordingly.
But, when I navigate back to the Friends View Controller, my selections or deselections do not change anything locally on the app. This means that a new user, even after selecting friends, essentially remains with an empty Friends Table View.
The following are my implementations for didSelectRowAtIndexPath and isFriend methods, as that is where I think the problem is. I update the self.friends mutable array property accordingly as well, so I don't quite know what's going wrong.
'''
-
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
PFUser *user = self.allUsers[indexPath.row]; PFRelation *friendsRelation = [self.currentUser relationforKey:@"friendsRelation"];
if ([self isFriend:user]) { cell.accessoryType = UITableViewCellAccessoryNone; for (PFUser *friend in self.friends) { if ([friend.objectId isEqualToString:user.objectId]) { [self.friends removeObject:friend]; break; } } [friendsRelation removeObject:user]; } else { cell.accessoryType = UITableViewCellAccessoryCheckmark; [self.friends addObject:user]; [friendsRelation addObject:user]; } [self.currentUser saveInBackgroundWithBlock: ^(BOOL succeeded, NSError *error) { if (error) { NSLog(@"Error %@ %@", error, error.userInfo); } }]; }
pragma mark - Helper Methods
- (BOOL)isFriend:(PFUser *)user { for (PFUser *friend in self.friends) { if ([friend.objectId isEqualToString:user.objectId]) { return YES; } } return NO; } '''
Thanks for the help in advance

4,354 PointsYes, it was resolved in the following thread https://teamtreehouse.com/forum/friend-lists-are-not-updating, which asked the same question after I originally did. At the bottom of the video, there is a note that there is a known error. That error is fixed both in the next stage and pointed out at the beginning of the next stage of the project, which involves giving the app a custom design.
