Custom UICollectionViewCell not loading - ios

Question

I'm using a storyboard and my custom UICollectionViewCell is not appearing. I played around with it for a few hours and have googled a ton of different solutions but none worked. Just to clarify, the data exists, and the UICollectionView is appearing, but the cell is not. Here is my code. Any suggestions would be appreciated!
- (NSInteger)collectionView:(UICollectionView *)mutualFriendsView numberOfItemsInSection:(NSInteger)section {
return [self.resultsDictionary count];
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)mutualFriendsView
cellForItemAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = #"PCRRequesterMutualFriendsCollectionViewCell";
PCRRequesterMutualFriendsCollectionViewCell *cell = [self.mutualFriendsView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
NSArray *idArray = [self.resultsDictionary objectForKey:#"id"];
NSArray *nameArray = [self.resultsDictionary objectForKey:#"name"];
cell.profileName.text = [nameArray objectAtIndex:indexPath.row];
cell.backgroundColor = [UIColor redColor];
return cell;
}
- (void)collectionView:(UICollectionView *)mutualFriendsView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"cell #%d was selected", indexPath.row);
}
- (BOOL)shouldAutorotate {
[mutualFriendsView.collectionViewLayout invalidateLayout];
BOOL retVal = YES;
return retVal;
}
EDIT Here is my viewDidLoad
self.mutualFriendsView.dataSource = self;
self.mutualFriendsView.delegate = self;
self.mutualFriendsView.pagingEnabled = YES;
// [self.mutualFriendsView registerClass:[PCRMutualFriendsCollectionViewCell class] forCellWithReuseIdentifier:#"PCRMutualFriendsCollectionViewCell"];
Edit I think I figured out the problem. I don't think the dictionary is being populated after the completion block finishes. Any suggestions for saving the value of the dictionary from the block to be used outside of it?
__block NSMutableDictionary *mutualFriends = nil;
__block NSNumber *total;
NSString *u = [NSString stringWithFormat:#"%#",self.details[#"Requester"][#"profile"][#"facebookId"]];
/* make the API call */
[FBRequestConnection startWithGraphPath:(#"/%#", u)
parameters:params
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
/* handle the result */
if (!error){
NSLog(#"RESULT OF FB %#", result);
if (result == nil){
NSLog(#"No shared friends");
} else {
total = result[#"context"][#"mutual_friends"][#"summary"][#"total_count"];
NSLog(#"TOTAL FRIENDS %#", total);
for(int i=0;i<[result[#"context"][#"mutual_friends"][#"data"] count];i++)
{
mutualFriends = result[#"context"][#"mutual_friends"][#"data"][i];
NSLog(#"FRIENDDATA %#", mutualFriends);
}
}
} else {
NSLog(#"ERROR %#", error);
}
}];
self.resultsDictionary = mutualFriends;
self.number = total;
NSLog(#"NUMBER %#", self.number);
NSLog(#"RESULTS DICTIONARY %#", self.resultsDictionary);
NSString *friends = [NSString stringWithFormat:#"You have %# friends in common including:", self.number];

Answer 1

After this code:
for(int i=0;i<[result[#"context"][#"mutual_friends"][#"data"] count];i++)
{
mutualFriends = result[#"context"][#"mutual_friends"][#"data"][i];
NSLog(#"FRIENDDATA %#", mutualFriends);
}
// add
self.resultsDictionary = mutualFriends;
mutualFriendsView.reloadData();
All within that completion block. So when FB finally does return and you've accumulated all the mutualFriends, then you tell the collectionView to reload.
