ios - 使用gestureRecognizer从 super View 中删除

Question

我创建了一个blurEffectView，如下所示:

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 View 中。

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

这是关闭它的函数:

func dismissBlurView(){
    blurEffectView.removeFromSuperview()
}

我显然在这里遗漏了一些东西，因为当我点击模糊 View 时不会调用dismissBlurView。

试试这个

class YourViewController: UIViewController, UIGestureRecognizerDelegate{

    tapGestureRecognizer.delegate = self

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