自定义注解Swift

Question

我已经创建了一个包含单个注释的地图。据我所见，这是一种非常简单的实现方法，我是从教程中学到的。我目前正在尝试获得一个自定义图片作为注释，但我正在努力做到这一点，因为几乎所有关于这个主题的信息都在objective C中。如果这真的很简单，请原谅我，但我对编码相对较新，如果有任何帮助，我将不胜感激:)

class ViewController2: UIViewController {
@IBOutlet var Map: MKMapView!

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.

//Location for first Pin
let locationOne = CLLocationCoordinate2DMake(-47.016945, 167.852095)

//Location for map centering
let locationNZ = CLLocationCoordinate2DMake(-43.937462, 170.507813)
let span = MKCoordinateSpanMake(9, 9)
let region = MKCoordinateRegion(center: locationNZ, span: span)
Map.setRegion(region, animated: true)

//Create annotation one
let annotation = MKPointAnnotation()
annotation.coordinate = locationOne
annotation.subtitle = "Park"
annotation.title = "Rakiura National Park"

//Add annotation to the map
Map.addAnnotation(annotation)}
