在iOS地圖中顯示若干註釋

Question

我正試圖顯示用戶的當前位置以及該地區附近的用戶。

我這樣做，顯示用戶的

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
    let location = locations.last 
    let center = CLLocationCoordinate2D(latitude:location!.coordinate.latitude ,longitude : location!.coordinate.longitude) 
    let span = MKCoordinateSpanMake(0.01,0.01) 

    let region = MKCoordinateRegion(center: center, span: span) 
    self.mapView.setRegion(region, animated: true) 
    self.manager.stopUpdatingLocation() 
} 

用戶 plotUsersonGraph(lat,longitude:long,title:"Apple HQ",subtitle:"Welcome to Apple")

func plotUsersonGraph(latitude:Double,longitude:Double,title:String,subtitle:String){ 
     let HQlocation = CLLocationCoordinate2DMake(latitude, longitude) 
     let span = MKCoordinateSpanMake(0.01, 0.01) 
     let region = MKCoordinateRegion(center: HQlocation, span: span) 
     // self.mapView.setRegion(region, animated: true)**THIS IS CAUSING PROBLEM** 

     let annotation = MKPointAnnotation() 
     annotation.coordinate = HQlocation 

     annotation.title = title 
     annotation.subtitle = subtitle 
     self.mapView.addAnnotation(annotation) 

    } 

我能夠單獨查看這兩個位置，但我無法合併到一起兩者繪製附近。 plotUsersonGraph將同時在圖上添加多個用戶。

這是我如何實現它

新增

  self.mapView.showsUserLocation = true 

內

func plotUsersonGraph(latitude:Double,longitude:Double,title:String,subtitle:String){ 
}
