UITableView not filling up with data - ios

Question

I'm having trouble implementing a toolbar (below my navigationbar) and a tableview. In my storyboard I created a normal ViewController, then made it part of the NavigationController, then added a UIToolBar and a UITableView. After this was done, I created the ViewController files. However, the tableview is not filling up with data. It's just empty rows...
ViewController.m
#import "TableViewController.h"
#import "AFHTTPRequestOperationManager.h"
#import "UIImageView+AFNetworking.h"
#import "Ninja.h"
#import "DetailViewController.h"
#import "AMSlideMenuMainViewController.h"
#import "UIViewController+AMSlideMenu.h"
#import "UIImageView+WebCache.h"
#import "NSString+FontAwesome.h"
#interface TableViewController ()
#property (nonatomic, strong)NSArray *ninjas;
#property (weak, nonatomic) IBOutlet UIBarButtonItem *movies;
#property (weak, nonatomic) IBOutlet UIBarButtonItem *shows;
#property (weak, nonatomic) IBOutlet UIBarButtonItem *profile;
#property (weak, nonatomic) IBOutlet UIToolbar *mainToolBar;
#end
#implementation TableViewController
- (void)viewWillAppear:(BOOL)animated
{
[self.navigationController setToolbarHidden:YES animated:YES];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = #"Your watched movies";
[self addRightMenuButton];
[self loadNinjas];
[self.movies setTitleTextAttributes:#{
NSFontAttributeName: [UIFont fontWithName:#"FontAwesome" size:24.0],
NSForegroundColorAttributeName: self.view.tintColor
} forState:UIControlStateNormal];
[self.movies setTitle:[NSString fontAwesomeIconStringForIconIdentifier:#"fa-dot-circle-o"]];
[self.shows setTitleTextAttributes:#{
NSFontAttributeName: [UIFont fontWithName:#"FontAwesome" size:24.0],
NSForegroundColorAttributeName: self.view.tintColor
} forState:UIControlStateNormal];
[self.shows setTitle:[NSString fontAwesomeIconStringForIconIdentifier:#"fa-pencil-square-o"]];
[self.profile setTitleTextAttributes:#{
NSFontAttributeName: [UIFont fontWithName:#"FontAwesome" size:24.0],
NSForegroundColorAttributeName: self.view.tintColor
} forState:UIControlStateNormal];
[self.profile setTitle:[NSString fontAwesomeIconStringForIconIdentifier:#"fa-plus"]];
self.mainToolBar.barTintColor = [UIColor whiteColor];
self.mainToolBar.layer.shadowColor = [[UIColor blackColor] CGColor];
self.mainToolBar.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
self.mainToolBar.layer.shadowRadius = 3.0f;
self.mainToolBar.layer.shadowOpacity = 1.0f;

I don't what is going wrong, maybe you guys do?

Answer 1

use this code in your :
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.dataSource=self;
self.tableView.delegate=self;
}
