ios - 从 View Controller MapKit 传递数据

Question

我意识到有从 View Controller 传递数据的解决方案。但是，我遇到的问题是我正在使用 Map Kit，我不确定将点击哪个 Pin 图它可能是以下之一:

 artworkPin = Artwork(title:"Wind Wand",locationName:"Majestic",discipline:"Statue",
                             coordinate:windwandcoord)
 artworkPin2 = Artwork(title:"Wind Wand2",locationName:" Not Majestic",discipline:"Statue",
                         coordinate:windwandcoord2)

我希望 ViewTwo(第二个 View Controller )上的标签显示为被单击的图钉“信息”按钮的标题。我目前将其设置为: var artworkPin:艺术品!

override func viewDidLoad() {
    super.viewDidLoad()
    art_title.text = artworkPin.title

仅加载标签作为 artworkPin(第一个图钉)的标题。 如有必要，附上代码: ViewTwo ViewControllerOne

感谢您的帮助。

Answer 1

However, the problem I am having is I am using Map Kit and I am unsure which Pin will be clicked on

func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
    if control == view.rightCalloutAccessoryView {
        if let artworkPin = view.annotation as? Artwork {
            performSegue(withIdentifier: "no", sender: artworkPin)
        }
    }
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if let identifier = segue.identifier {
        if identifier == "no" {
            if let artworkPin = sender as? Artwork {
                let ViewTwo = segue.destination as! ViewTwo
                ViewTwo.artworkPin = artworkPin
            }
        }
    }
}
