# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

Set on viewDidLoad()

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

self.tableView.backgroundColor = UIColor.whiteColor()

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