Disable swipe in UIPageViewController

I have a UIViewController with UIPageViewController variable.

I am trying to disable the swiping for the UIPageViewController for certain positions on screen. I am doing this by setting the UIViewController as a UIGestureRecognizerDelegate and setting the gesture recognizers in the UIPageViewController delegate to self (the UIViewController). I can't seem to find where the gesture recognizers are or get loaded for the UIPageViewController.

I've tried these three places and all come up empty in the viewDidLoad method:

println("gesture\(self.pageViewController!.gestureRecognizers)")
println("gesture\(self.view.gestureRecognizers)")
println("gesture\(self.pageViewController!.view.gestureRecognizers)")

UPDATE*******************:

so I found some UIGestureRecognizers hiding in the navigationController, but adding them as delegates and running the code below does nothing. Is it because I have the wrong UIGestureRecognizers. There is one in there that is a UIPanGestureRecognizer as well. Why don't I get any recognizers in my page controller or the view of my page controller?

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
    println("Should recieve touch")
    return false
}

I am getting the "Should receive touch" to print to the logs but I return false and no swiping is disabled. What am I doing wrong?

By the past i have tried to do something similar with a UIScrollView. UIScrollView have member named panGesture. But you can loop on pageViewControllerGesture like this (tested on a standard Page-based application) :

 override func viewDidLoad() {
    super.viewDidLoad()

    // other set up

    // loop over your pageViewController gestures
    for gesture in self.pageViewController!.gestureRecognizers
    {
        // get the good one, i discover there are 2
        if(gesture is UIPanGestureRecognizer)
        {
            // replace delegate by yours (Do not forget to implement the gesture protocol)
            (gesture as! UIPanGestureRecognizer).delegate = self
        }
    }

}

func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool
{
    // add custom logic
    var ShouldISwipe = rand()%2 == 0
    println("Should I Swipe : \(ShouldISwipe)")
    return ShouldISwipe
}

I have found that link that could help too (should be converted to swift) : http://www.lukaszielinski.de/blog/posts/2014/03/26/restrict-panning-of-uipageviewcontroller-to-certain-area/

Hope that could help.
