No results Tableview

When data source count is zero create a label with no result message and add it as the background view of table view

 UILabel *messageLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
    messageLabel.text = @"No data is currently available.";
    messageLabel.textColor = [UIColor blackColor];
    messageLabel.numberOfLines = 0;
    messageLabel.textAlignment = NSTextAlignmentCenter;
    messageLabel.font = [UIFont fontWithName:@"Palatino-Italic" size:20];
    [messageLabel sizeToFit];
    self.tableView.backgroundView = messageLabel;
    self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
