Set delegate to an object

This is the first time im trying to set a UITableView delegate/datasource to an instance of an object.

I have a UIView managed by a class called hMain, and a UITableView inside of main managed by an instance of a class called vTable.

hMain.h:

@interface hMain : UIViewController
@property (strong, nonatomic) IBOutlet vTable *voteTbl;   
@end

hMain.m:

- (void)viewDidLoad
{
[super viewDidLoad];

voteTbl = [[vTable alloc]init];
[self.voteTbl setDelegate:voteTbl];
[self.voteTbl setDataSource:voteTbl];

}

vTable.h:

@interface vTable : UITableView <UITableViewDelegate , UITableViewDataSource>
@end

vTable.M:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 5;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [UITableViewCell configureFlatCellWithColor:[UIColor greenSeaColor] selectedColor:[UIColor wetAsphaltColor] reuseIdentifier:CellIdentifier inTableView:(UITableView *)tableView];

    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        [cell configureFlatCellWithColor:[UIColor greenSeaColor] selectedColor:[UIColor wetAsphaltColor]];
    }

    cell.textLabel.text = @"Hello there!";

    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"Row pressed!!");
}

This is really my first time straying away from IB and doing things programatically so im not sure im settings delegates and things correctly. This is also my first attempt and setting a delegate/datasource outside of self.

My problem is the table is coming out blank every time.

What is vTable? Looks like you have a "voteTable" class (BTW: classes should start with an uppercase char, instance variables should start with lowercase). Anyhow, looks like your main problem is you forgot to add the table as a subview and set its frame. eg:

self.voteTbl = [[VoteTable alloc] init];
self.voteTbl.delegate = self;
self.voteTbl.dataSource = self;
self.voteTbl.frame = self.view.bounds;
[self.view addSubView:self.voteTbl];
