    I don't think that swipe gestures offer support for the kind of behavior you are aiming at, but you can easily accomplish it by doing the following:

    1. on the first swipe, set a flag and start a timer; for the rest do nothing;

    2. on the second swipe,

      a. if the timer has fired (when firing, the timer reset the flag), do as per point 1.

      b. is the timer has not fired (the flag is still set), then do you action and cancel the timer.

    You might event think of defining a subclass of UISwipeGestureRecognizer to encapsulate all this behavior.
