Hide keyboard when scroll UITableView

Here is the cleanest way to achieve this in iOS 7.0 and above:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;

Or to dismiss interactively when touching:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

Or in Swift:

tableView.keyboardDismissMode = .onDrag

To dismiss interactively:

tableView.keyboardDismissMode = .interactive
