TableView do not enter in willDisplayCell

Question

My goal is define my own cell style, with background, font and size. I try this.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    ScreenListElements *currentScreenElement = [self.screenDefBuild.elementsToTableView objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:currentScreenElement.objectName];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:currentScreenElement.objectName];

    }

    cell.textLabel.text = currentScreenElement.objectName;

    return cell;
}

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{  
cell.contentView.backgroundColor = [UIColor blackColor];
}

I would like to change cell backgrond, but my app doesn't enter to willDisplayCell method. I have declared my class as:

@interface MyTableView : UIViewController  <UITableViewDataSource,NSCopying> {
}

Should i have something else? Or maybe is a better way to declare own cell style.

Answer 1

@interface MyTableView : UIViewController  <UITableViewDataSource, UITableViewDelegate ,NSCopying> {
}

the method

tableView:willDisplayCell:forRowAtIndexPath

is delegate method of UITableView

EDITED (to make it correct & accepted answer)

setting delegate

[myTableView setDelegate:self];
