這是不可能
從UIPageViewController.h
// An array of UIGestureRecognizers pre-configured to handle user interaction. Initially attached to a view in the UIPageViewController's hierarchy, they can be placed on an arbitrary view to change the region in which the page view controller will respond to user gestures.
// Only populated if transition style is 'UIPageViewControllerTransitionStylePageCurl'.
@property(nonatomic, readonly) NSArray *gestureRecognizers;
通知的只有填充如果過渡的風格是 'UIPageViewControllerTransitionStylePageCurl'。
這裏有一個解決辦法 UIPageViewController returns no Gesture Recognizers in iOS 6
