Ios 在Swift 3中过滤地图注释

我有一个MapView控制器，它包含注释以及其他数据，例如细节和图像信息。我正在尝试过滤注释及其关联数据，然后在单击callout附件控件中的DetailExposition按钮时将数据传递给DetailView控制器

我只能单独传递信息。我可以将注释标题和所有注释的数据传递给DetailView控制器。但我的目标是选择注释，单击DetailExposition按钮，传递所选注释的信息，并在DetailView控制器中查看标题、副标题、详细信息和图像名称

如有任何见解，将不胜感激

以下是我一直在研究的代码：

class LocationAnnotation: NSObject, MGLAnnotation {

var customPointAnnotation = CustomPointAnnotation()
var location: Location?
var coordinate: CLLocationCoordinate2D
var title: String?
var subtitle: String?
var imageObj = ""
var details: String?

init(coordinate: CLLocationCoordinate2D, title: String, subtitle: String, imageObj: String, details: String, location: Location? = nil) {
    self.coordinate = coordinate
    self.title = title
    self.subtitle = subtitle
    self.imageObj = imageObj
    self.details = details
}
}

我最终能够通过调用CustomPointAnnotation来传递每个选定位置的数据。以下是有帮助的：

在

prepare（对于segue:sender:）

中，执行类似于

controller.location=myMapView.selectedAnnotations的操作。首先
如何将数据设置到mapView中？链接字典和位置的代码在哪里？我用一个解决方案更新了我的问题。感谢您的建议。在
