ios - 如何在 View 外部轻击时关闭iPad上的popover View Controller :IOS 9

我试图使用类型为.pagesheet的模式样式将视图控制器呈现为popoverviewcontroller。在这里，我试图添加点击手势识别器，以在单击其视图时关闭此popoverviewcontroller。但它无法在iOS 9中检测到敲击。这是手势识别器下面的代码

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        let recog : UITapGestureRecognizer = UITapGestureRecognizer.init(target: self, action:#selector(HandleTap))
        recog.numberOfTapsRequired = 1
        recog.numberOfTouchesRequired = 1
        recog.cancelsTouchesInView = false
        recog.delegate = self
        self.view.window?.addGestureRecognizer(recog)

    }


func HandleTap(sender:UITapGestureRecognizer) -> Void
{
    if(sender.state == UIGestureRecognizerState.Ended)
    {
        var location : CGPoint = sender.locationInView(self.presentingViewController?.view)
        //var location : CGPoint = sender.locationInView(self.view?.window)
        if(!(self.view.pointInside(self.view.convertPoint(location, toView: self.view?.window), withEvent: nil)))
        {
          self.view.window?.removeGestureRecognizer(sender)
          self.dismissViewControllerAnimated(true, completion: nil)
        }
    }
}

最佳答案

在要处理轻敲的userinteractionenable上将true设置为view。还有第二件事，为什么要用viewDidAppear做东西？您应该使用viewDidLoad添加手势识别器。

更新:

self.view.window?.userInteractionEnabled = true

如果您正在使用导航控制器，则

self.navigationController?.view.window?.userInteractionEnabled = true

希望thiw会有所帮助:)
