使用gestureRecognizer从超级视图中删除

Question

我这样创建一个blurEffectView：

var blurEffectView: UIVisualEffectView{
    let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = self.view.bounds
    blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    return blurEffectView
}

然后将tapGestureRecognizer添加到效果视图。

let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.dismissBlurView))
            self.blurEffectView.addGestureRecognizer(tapGestureRecognizer)
            self.mapView.addSubview(self.blurEffectView)

这是消除它的功能：

func dismissBlurView(){
    blurEffectView.removeFromSuperview()
}

我显然在这里丢失了一些东西，因为当我点击模糊视图时不会调用dismissBlurView。

Answer 1

尝试这个

class YourViewController: UIViewController, UIGestureRecognizerDelegate{

    tapGestureRecognizer.delegate = self

    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
            return true
    }
}

Answer 2

尝试使用此代码，因为它对我有用。 我更改了块声明，并在viewDidLoad中设置了块外部的帧大小。

var blurEffectView: UIVisualEffectView = {
        let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        return blurEffectView
   }()

//在viewDidLoad中设置UIVisualEffectView框架

self.blurEffectView.frame = self.view.bounds

        self.blurEffectView.addGestureRecognizer(UITapGestureRecognizer.init(target: self, action: #selector(self.dismissBlurView(gesture:))))
        self.view.addSubview(self.blurEffectView)

func dismissBlurView(gesture: UITapGestureRecognizer){
        blurEffectView.removeFromSuperview()
    }
