To make sure that multiple gesture recognizers can work together you have to implement the method shouldRecognizeSimultaneouslyWithGestureRecognizer and return true:

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

Sorry for the Swift code but you should get the idea.

This method must be implemented even if you are using a single gesture recognizer because the view can have its own (system) recognizers, such as MKMapView.
