ios - Xcode7 swift2-双击MKMapView不起作用

我运行以下代码，并且没有错误。长按正常，双击不起作用。添加双击手势之前，我已禁用缩放。

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    manager  = CLLocationManager()
    manager.delegate = self
    manager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
    manager.requestWhenInUseAuthorization()
    manager.startUpdatingLocation()
    routeMapView.zoomEnabled = false
    routeMapView.showsPointsOfInterest = true

    let doubleTapGesture = UITapGestureRecognizer(target: self, action: "routeMapDoubleTapSelector:")
    doubleTapGesture.numberOfTapsRequired = 2
    routeMapView.addGestureRecognizer(doubleTapGesture)

    let ulpgr = UILongPressGestureRecognizer(target: self, action:"routeMapLongPressSelector:")
    ulpgr.minimumPressDuration = 2.0
    routeMapView.addGestureRecognizer(ulpgr)


}

有什么帮助吗？

最佳答案

我尝试了您的代码，它似乎运行良好。打印“双击”。这是测试代码。

import UIKit
import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate {

let manager = CLLocationManager()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    manager.delegate = self
    manager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
    manager.requestWhenInUseAuthorization()
    manager.startUpdatingLocation()

    let routeMapView = MKMapView()
    self.view = routeMapView

    routeMapView.zoomEnabled = false
    routeMapView.showsPointsOfInterest = true

    let doubleTapGesture = UITapGestureRecognizer(target: self, action: "routeMapDoubleTapSelector:")
    doubleTapGesture.numberOfTapsRequired = 2
    routeMapView.addGestureRecognizer(doubleTapGesture)

    let ulpgr = UILongPressGestureRecognizer(target: self, action:"routeMapLongPressSelector:")
    ulpgr.minimumPressDuration = 2.0
    routeMapView.addGestureRecognizer(ulpgr)
}

func routeMapDoubleTapSelector(sender: AnyObject) {
    NSLog("double taps")
}

func routeMapLongPressSelector(sender: AnyObject) {
    NSLog("long press")
}
}
