{Swift}让引脚连接？

Question

我没有找到如何链接到我的让利=销 请帮助我

我的第一个代码：

@IBOutlet weak var Point1S: MKMapView! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    let location = CLLocationCoordinate2DMake(43.429837, 5.434837) 

    Point1S.setRegion(MKCoordinateRegionMakeWithDistance(location, 500, 500), animated: true) 

    let pin = here 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

二码：

import MapKit 

class MKPinAnnotationView : NSObject , MKAnnotation { 
    var title: String? 
    var subtitle: String? 
    var coordinate: CLLocationCoordinate2D 

    init(title : String , subtitle : String , coordinate : CLLocationCoordinate2D) { 

     self.title = title 
     self.subtitle = subtitle 
     self.coordinate = coordinate 
    } 

} 

我不知道怎么把我的在让销的第一代码=第二码
