ios - 如何在 Swift 中提取纬度/经度 placemark.coordinate？

Question

我在我的应用程序中添加了位置搜索栏。 tableview Controller 由用户位置纬度/经度以及目的地(地址用户输入到搜索栏中)组成。据我所知，纬度/经度在 placemark.coordinate 内:

placemark.coordinate = CLLocationCoordinate2D(latitude: 45.253519203737767, longitude: -66.070974382763978)

我有两个变量:destLat 和 destLong。如何从 placemark.coordinate 中提取纬度和经度并将其放入上述两个变量中？

相关代码:

// cache the pin
    selectedPin = placemark

    // clear existing pins
    mapView.removeAnnotations(mapView.annotations)
    let annotation = MKPointAnnotation()
    annotation.coordinate = placemark.coordinate
    annotation.title = placemark.name
    if let city = placemark.locality,
        let prov = placemark.administrativeArea {
        annotation.subtitle = "\(city), \(prov)"
    }

    let destination = placemark.coordinate
    print("Destination coordinates: \(destination)")
    let name = placemark.name
    print("Placemark Name: \(name!)")


    mapView.addAnnotation(annotation)
    let span = MKCoordinateSpanMake(0.05, 0.05)
    let region = MKCoordinateRegionMake(placemark.coordinate, span)
    mapView.setRegion(region, animated: true)

控制台输出:

也许你想多了。您可以像任何其他变量一样为这些变量赋值:

let (destLat, destLong) = (placemark.coordinate.latitude, placemark.coordinate.longitude)
