Answer 1

Set frame like this

  [dowMapBt setFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];

And also check the size of the image you are setting

Answer 2

Just Add button as a subview of cell after creating cell.First check if cell is nil or not.

if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    [dowMapBt setFrame:CGRectMake(0, 0, cell.frame.size.width, 30)];
    [dowMapBt addTarget:self action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside];
    [cell addSubview:dowMapBt];
}

Ater this return cell
