我的地图上有20个引脚，每张单击时，单击时显示了带有场地名称的注释，右侧有一个标注按钮。我已经成功地将此按钮链接到了单个页面。事情是所有位置链接到同一页面。我想要20个单独的页面，每个页面指向特定的别针。我在网上发现的几乎所有示例都希望生成一个带有信息的单个页面。这是我拥有的代码。

和处理注释的脚本
import Foundation
import MapKit
import Contacts
class Artwork: NSObject, MKAnnotation {
let title: String?
let locationName: String
let discipline: String
let coordinate: CLLocationCoordinate2D
let venueNo: Int
init(title: String, locationName: String, discipline: String, coordinate: CLLocationCoordinate2D, venueNo : Int) {
self.title = title
self.locationName = locationName
self.discipline = discipline
self.coordinate = coordinate
self.venueNo = (venueNo)
super.init()
}
var subtitle: String? {
return locationName
}
}
我是Swift的新手，如果有人可以提供帮助，我会很乐意。我一直在试图弄清楚5天，所以我想我会提供帮助。
您可以区分注释取决于Artwork的Venueno属性：
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView,
calloutAccessoryControlTapped control: UIControl) {
guard let artwork = view.annotation as? Artwork else { return }
let annotaionVenueNo = artwork.venueNo
print("veneueNo = %d", annotaionVenueNo)
// do additional process depend on annotaionVenueNo
}
