iOS 9 Swift添加引脚和当前位置注释

Question

尝试添加一个显示当前位置和地图上的图钉的注释，但是当前位置和我要添加的图钉都会添加为图钉。如果我更改了行＆＃34; view = MKPinAnnotationView（annotation：annotation，reuseIdentifier：＆＃34; annotation＆＃34;）＆＃34; to＆＃34; view = MKAnnotationView（注释：注释，reuseIdentifier：＆＃34;注释＆＃34;）＆＃34;两个引脚都没有添加！ 救命！

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
    //Try to dequeue an annotation like in the table view
    var view = mapView.dequeueReusableAnnotationViewWithIdentifier("annotation")
    //If you can't dequeue an annotation create one, use the same identifier as above that way these annotations you create down here can be reused eventually.
    if view == nil {
        view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "annotation")
        view?.canShowCallout = true
    }else{
        return view
    }

    return view
}

提前多多感谢。
