Question

我遇到了UIPageViewController问题。我做了什么？ 1.在pageViewController上，您可以向左，向右滑动以更改VC 2.增加横向菜单。添加横向菜单时，我创建了pangesture识别器并将其添加到pageContentVC（因此我可以拖动pageContentVC以关闭侧边栏菜单）

 var menuViewController: UIViewController! {
    didSet {
        self.exitPanGesture = UIPanGestureRecognizer()
        self.exitPanGesture.addTarget(self, action:"handleOffstagePan:")
      //  self.exitPanGesture.view?.userInteractionEnabled = false
        self.sourceViewController.view.addGestureRecognizer(self.exitPanGesture)

    }
}

这里我将pageContentVC设置为transitionManager的sourceVC：

 func resetToMainPage(index: Int!) {
    /* Getting the page View controller */
    mainPageViewController = self.storyboard?.instantiateViewControllerWithIdentifier("MainPageViewController") as UIPageViewController
    self.mainPageViewController.dataSource = self
    self.mainPageViewController.delegate = self

    let pageContentViewController = self.viewControllerAtIndex(index)

    self.transtionManger.sourceViewController = pageContentViewController // adding swipe to the pageContentViewControlle in order to close menu

    self.mainPageViewController.setViewControllers([pageContentViewController!], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)


    self.mainPageViewController.view.frame = CGRectMake(0, 102, self.view.frame.width, self.view.frame.height)
    self.addChildViewController(mainPageViewController)
    self.view.addSubview(mainPageViewController.view)
    self.mainPageViewController.didMoveToParentViewController(self)

}

关闭菜单后，我禁用了pangesture识别器。 `var presentingP：Bool！{ didSet { 如果presentP == true { //仅在显示menucontroller视图时启用手势识别器
```
        self.exitPanGesture.view?.userInteractionEnabled = true
    }else{
        // disable gesture recognizer when menu is not presented
        self.exitPanGesture.view?.userInteractionEnabled = false

        isMenuVisible = false
    }
}
```
} `Sofar，我可以向左滑动，向右滑动以改变VC。问题是我无法在VC上滚动tableView。禁用pageContentVC手势后，除了向右和向左滑动（更改VC）外，一切都会变为禁用状态。问题：如何在一个视图中保留两个gestureRecognizer并在它们之间切换？

您可以使用enabled UIGestureRecognizer属性禁用您不想使用的属性并启用另一个属性。
