Question

为了自定义预览文件控制器，我创建了DocumentPreviewController: UIController，然后创建了DocumentPreviewController.view.addSubView(QLPreviewController.view)。如果我全屏显示QLPreviewController.view，即使我为touch event添加了UIGestureRecognizer，也无法收到任何QLPreviewController.view，并监控DocumentPreviewController中的所有触摸事件}。任何人都可以帮助我吗？

import UIKit
import QuickLook

class CustomiseDocumentPreviewController: UIViewController, UIGestureRecognizerDelegate
 {

    var url : String!
override func viewDidLoad()
{
   let previewController =  CustomisePreviewController()
    previewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, 300)
    previewController.filePath = url

    let singleGuesture = UITapGestureRecognizer()
    singleGuesture.addTarget(self, action: #selector(GlipDocumentPreviewController._singleTap))
    singleGuesture.numberOfTapsRequired = 1
    singleGuesture.delegate = self
    previewController.view.userInteractionEnabled = true
    previewController.view.addGestureRecognizer(singleGuesture)
    previewController.view.multipleTouchEnabled = true

    self.view.backgroundColor = UIColor.redColor()
    self.view.addSubview(previewController.view)
}

func _singleTap()
{
    if self.navigationController!.navigationBarHidden
    {
        self.navigationController?.setNavigationBarHidden(false, animated: true)
    }
    else
    {
        self.navigationController?.setNavigationBarHidden(true, animated: true)
    }
    //        self.navigationController?.navigationBarHidden = !(self.navigationController!.navigationBarHidden)
    print("====")
}

func previewController(controller: QLPreviewController, shouldOpenURL url: NSURL, forPreviewItem item: QLPreviewItem) -> Bool {

func previewControllerDidDismiss(controller: QLPreviewController)

}

func previewControllerWillDismiss(controller: QLPreviewController)

}

我已向CustomiseDocumentPreviewController.view和CustomisePreviewController.view添加单个触摸事件，您可以从我的代码中看到，屏幕上半部分为CustomisePreivewController.view，如果我触摸该空间，什么都没发生。但是，如果我触摸下面的屏幕，它可以工作。我搜索了几天，似乎我们无法从QLPreviewController获得触摸事件？ 1.如果您有任何方法可以听取QLPreviewController.view＆＃39;触摸事件，请帮帮我。 2.如果不能，如果需要自定义预览文件控制器，将如何操作。

无法从QLPreviewController.view接收任何触摸事件
