Set on viewDidLoad()

self.tableView.backgroundColor = UIColor(patternImage: UIImage(named: "empty-cell.png")!)

Where ever you call your table reload after API call add this line:
self.tableView.backgroundColor = UIColor.whiteColor()

Here is the empty cell image used as a background pattern I made:
