mapView.delegate = self與當前位置

Question

我將我的mapView代理設置爲自我，以便我的引腳標註起作用，當我這樣做時，我的當前位置也顯示爲引腳。我該如何解決這個問題？ enter image description here

mapView.delegate = self 


    self.locationManager.delegate = self 


    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest 


    self.locationManager.requestWhenInUseAuthorization() 


    self.locationManager.startUpdatingLocation() 


    self.mapView.showsUserLocation = true 

Answer 1

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {  
    if annotation.isKindOfClass(MKUserLocation) { 
     return nil 
    } 
} 

Answer 2

func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! { 

     if (annotation is MKUserLocation) { 

      return nil 
     }
