UITableView isn't working - objective-c

Question

Im trying to make a comments UITableView inside a UIViewController but I'm having problems. If I set the text directly, it shows up (cell.username.text) but if I try to fill it with a PFQuery (parse.com) nothing shows up
//DetailViewController.h
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#interface DetailViewController : UIViewController{
}
#property (strong, nonatomic) PFObject *place;
#property (strong, nonatomic) IBOutlet PFImageView *userPhoto;
#property (strong, nonatomic) IBOutlet UILabel *username;
#property (strong, nonatomic) IBOutlet UILabel *message;
#property (strong, nonatomic) IBOutlet UILabel *distance;
#property (strong, nonatomic) IBOutlet UILabel *checkCount;
#property (strong, nonatomic) IBOutlet PFImageView *photo;
#property (strong, nonatomic) IBOutlet UIScrollView *scroller;
#property (strong, nonatomic) IBOutlet UITableView *commentsTableView;
- (IBAction)checkMarkButton:(UIButton *)sender;
#end
//DetailViewController.m
#import "DetailViewController.h"
#import "CommentsViewController.h"
#interface DetailViewController (){
CommentsViewController *test;
}
#end
#implementation DetailViewController
#synthesize place;
#synthesize userPhoto, message, username, checkCount, photo, scroller, commentsTableView;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
test = [[CommentsViewController alloc] init];
self.commentsTableView.delegate = test;
self.commentsTableView.dataSource = test;
[test commentsQuery:place];
}
//CommentsViewController.h
#import <Parse/Parse.h>
#interface CommentsViewController : UITableViewController{
}
#property (strong, nonatomic) PFObject *place;
- (void)commentsQuery:(PFObject *)object;
#end
//CommentsViewController.m
#import "CommentsViewController.h"
#import "DetailViewController.h"
#import "CommentsCell.h"
#interface CommentsViewController (){
NSArray *commentsArray;
}
#end
#implementation CommentsViewController
#synthesize place;
- (void)commentsQuery:(PFObject *)object {
place = object;
PFQuery *query1 = [PFQuery queryWithClassName:#"activity"];
[query1 whereKey:#"type" equalTo:#"comment"];
[query1 whereKey:#"place" equalTo:place];
[query1 orderByDescending:#"createdAt"];
[query1 findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error){
commentsArray = [[NSArray alloc]initWithArray:objects];
NSLog(#"%lu", (unsigned long)[commentsArray count]);
}
}];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [commentsArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
static NSString *CellIdentifier = #"Cell";
CommentsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[CommentsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
PFObject *tempObj = [commentsArray objectAtIndex:indexPath.row];
cell.username.text = #"username";
cell.comment.text = [tempObj objectForKey:#"content"];
cell.userThumbnail.file = [tempObj objectForKey:#"userThumbnail"];
[cell.userThumbnail loadInBackground];
return cell;
}
#end

My problem was calling reloadData. I followed the answer here and it works UITableView delegate and datasource in a separate class after parsing
