Why UITableView is empty?

Question

I would like build menu in UITableView, but I'm doing something wrong. What I do wrong? I get empty UITableView. I don't know, what's wrong. Maybe some idea?
This is my code:

.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    IBOutlet UITableView *tblSimpleTable;
    NSMutableArray *array1;
    UIBarButtonItem *addButton;
    BOOL manyCells;
    UIView *headerView;
    UITapGestureRecognizer  *headerTapped;
    NSMutableArray *history;
    NSString *valueToSave;
    NSMutableArray      *sectionTitleArray;
    NSMutableDictionary *sectionContentDict;
    NSMutableArray      *arrayForBool;
    UITableView *table;
}

- (IBAction) EditTable:(id)sender;

@end

.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

    // Do any additional setup after loading the view, typically from a nib.

    if (!sectionTitleArray) {

Help me:)

Answer 1

You have to set tableview delegate method in viewDidload method

tblView.delegate = self;
tblView.dataSource = self;

Also one more thing, you have to set UITableViewDataSource, UITableViewDelegate in header file.

Answer 2

Write in h file

       UITableViewDelegate,UITableViewDataSource

and in .m File

       table = [[UITableView alloc]initWithFrame:CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height)];
       table.Delegate=self;
       table.DataSource=self;

    [self.view addSubview:table];
