ios - UIGestureRecognizer 不起作用并使应用变慢

Question

在 map View 中，我想做的是，如果用户触摸 map 中的任何地方，应用程序将停止更新位置..但似乎什么都没有发生，并且需要大约 10-15 秒的时间才能在应用程序中执行操作(使应用程序真正缓慢而滞后)我一直在使用这段代码:

 @IBOutlet var Map: MKMapView!

    let locationManager = CLLocationManager()
     override func viewDidLoad() {
        super.viewDidLoad()
        StopUpdate.hidden = true
        Longi.hidden = true
        Lati.hidden = true
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.requestLocation()
        locationManager.startUpdatingLocation()
        locationManager.stopUpdatingLocation()
    self.view.addGestureRecognizer(UIGestureRecognizer(target: self, action: "tapClose"))
}

func tapClose(gesture: UITapGestureRecognizer){
    locationManager.stopUpdatingLocation()
    StopUpdate.hidden = true
    UpdateLocation.hidden = false
}

由于 GestureRecognizer，我的应用程序运行缓慢且有延迟。对此有任何解决方案吗？

添加UITapGesture的正确方法

class DashVC: UIViewController, UIGestureRecognizerDelegate{
}

像这样在 viewdidload 中定义 tapsture

let tapDashBoard = UITapGestureRecognizer(target: self, action: #selector(DashVC.DashBoardTapped(_:)))
    tapDashBoard.delegate = self
    view.addGestureRecognizer(tapDashBoard)

和行动

    func DashBoardTapped(sender: UITapGestureRecognizer? = nil) {
}
