UitableViewCell not properly displaying accessories - ios

Question

I have a friendslist view controller that allows the user to see pending friend requests. The isPending method is first used to see if a particular user has a pending friend request with the current user.
-(BOOL)isPending:(PFUser *)user
{
for (PFUser *pending in self.Pending){
if ([pending.objectId isEqualToString:user.objectId]){
return YES;
}
}
return NO;
}
This method is called within cellForRowAtIndexPath method inside the TableViewController. THe problem that I am experiencing is that If I run the query inside the tableViewController users who are pending are properly displayed. When I moved the query to a singleton datasource class, I have setup a delegate method that is called when data is returned from the query.
-(void)pendingFriendsQuarryDidFinishWithData{
self.Pending = [NSMutableArray arrayWithArray:dataHolder.getPendingFriendsList];
[self.tableView reloadData];
}
Calling reloadData does not cause the checkmarks to appear next to the users names.
EDIT: Here is the code for cellForRowAtIndexPath. It does not change with the singleton.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
// Configure the cell...
PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
cell.textLabel.text = user.username;
cell.detailTextLabel.text = user.email;
cell.imageView.image = [UIImage imageNamed:#"Treehouse.png"];
if([self isPending:user]){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
return cell;
}
What does change is how the data is obtained. Without the singleton here is the code
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
/*
self.currentUser = [PFUser currentUser];
if (self.currentUser != nil){
PFQuery *userQuery = [PFUser query];
PFQuery *pendingUser = [PFUser query];
PFRelation *friendRelation = [self.currentUser relationForKey:#"friendRelation"];
PFQuery *existingFriends = [friendRelation query];
PFQuery *pendingFriends = [PFQuery queryWithClassName:#"FriendRequest"];
userQuery.cachePolicy = kPFCachePolicyCacheThenNetwork;
pendingFriends.cachePolicy = kPFCachePolicyCacheThenNetwork;
[pendingFriends whereKey:#"fromUser" equalTo:self.currentUser.objectId];
[pendingFriends whereKey:#"status" equalTo:#"Pending"];
[userQuery whereKey:#"objectId"doesNotMatchKey:#"toUser" inQuery:pendingFriends];
[userQuery whereKey:#"objectId" doesNotMatchKey:#"objectId" inQuery:existingFriends];
[userQuery orderByAscending:#"username"];
[userQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error){
NSLog(#" Error %# %#", error, [error userInfo] );
}else{
NSLog(#"All Users Array Starts Here: %#", objects);
self.allUsers = objects;
[self.tableView reloadData];
}
}];
[pendingUser whereKey:#"objectId" matchesKey:#"toUser" inQuery:pendingFriends];
[pendingUser orderByAscending:#"username"];
[pendingUser findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error){
NSLog(#"%# %#", error, [error userInfo]);
}else{
[self.Pending addObjectsFromArray:objects];
NSLog(#"Pending Friends Array Stars here: %#", self.Pending);
}
}];
}
*/
}
With singleton
- (void)viewDidLoad
{
dataHolder = [DataHolder sharedInstance];
dataHolder.delegate = self;
self.friends = [NSMutableArray new];
self.allUsers = [NSMutableArray new];
self.allUsers = [NSMutableArray arrayWithArray:dataHolder.getAllUsersWithQuarry];
self.Pending = [NSMutableArray new];
self.Pending = [NSMutableArray arrayWithArray:dataHolder.getPendingFriendsListWithQuarry];
[super viewDidLoad];
NSLog(#"Now in Connection Editor");
}
-(void)allUsersQuarryDidFinishWithData{
self.allUsers = [NSMutableArray arrayWithArray:dataHolder.getAllUsers];
[self.tableView reloadData];
}
-(void)pendingFriendsQuarryDidFinishWithData{
self.Pending = [NSMutableArray arrayWithArray:dataHolder.getPendingFriendsList];
[self.tableView reloadData];
}

Silly question, did you set the datasource of your tableviewcontroller to point to your singleton datasource?
tableview.datasource = [your singleton class instance]
and make sure that you step into it in the debugger.
Hope this helps.
