我在我的视图中使用谷歌地图。我想为ma视图实现touchBegin和touchEnd事件，但不会触发事件。
import UIKit
import GoogleMaps
import GooglePlaces
import GooglePlacePicker
class Home_ViewController: UIViewController, GMSMapViewDelegate, CLLocationManagerDelegate ,UINavigationControllerDelegate , UICollectionViewDataSource, UICollectionViewDelegate{
//Locals
private var DefaultLocation = CLLocationCoordinate2D(latitude: 6.914023, longitude: 79.887243)
private var CurrentLocation = CLLocationCoordinate2D(latitude: 0.00000, longitude: 0.00000)
var _DefaultClass = ""
//Locals
//UI OutletControls
@IBOutlet weak var barBtn: UIBarButtonItem!
@IBOutlet weak var navigationView: UIView!
@IBOutlet weak var vehicleClassesCollectionView: UICollectionView!
@IBOutlet weak var mapView: GMSMapView!
@IBOutlet weak var destinationButton: UIButton!
//UI OutletControls
override func viewDidLoad() {
super.viewDidLoad()
//Setting up Views
self.view.addSubview(self.mapView)
self.mapView.addSubview(self.navigationView)
self.mapView.addSubview(self.vehicleClassesCollectionView)
self.mapView.addSubview(self.destinationButton)
self.mapView.userInteractionEnabled = true
}//viewDidLoad
// touch events//
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
NSLog("touch")
super.touchesBegan(touches, withEvent: event)
let touch: UITouch = touches.first! as UITouch
if(touch.view == self.mapView)
{
NSLog("touch view")
}}
有人能告诉我为什么触摸事件不起作用吗？
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
NSLog("touchm")
super.touchesBegan(touches, withEvent: event)
let touch: UITouch = touches.first! as UITouch
if(touch.view == self.mapView)
{
NSLog("touch viewm")
}
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
NSLog("touche")
super.touchesBegan(touches, withEvent: event)
let touch: UITouch = touches.first! as UITouch
if(touch.view == self.mapView)
{
NSLog("touch viewe")
}
}

答案 0 :(得分：0)
可能视图位于另一个未启用用户交互的UIView中。不是吗？
