我的地图上有20个针脚，每个针脚点击时会显示一个带有场地名称的注释，并在右侧有一个标注按钮。我已经使用segue将此按钮成功链接到单个页面。事情是所有位置都链接到同一页面。我想要20个单独的页面，每个页面链接到一个特定的引脚。我在网上发现的几乎所有例子都想生成一个传入信息的单页。这是我的代码。

}
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
}
}
我对Swift很新，如果有人可以提供帮助，我会很高兴。我一直试图弄清楚它5天，所以我想我会帮忙。
答案 0 :(得分：0)
您可以根据Artwork的venueNo属性来区分注释：
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
}
