将地址转换为swift坐标

Question

如何使用Swift将String地址转换为CLLocation坐标？我还没有代码，我找了一个解决方案，但我还没找到任何人。

谢谢。

Answer 1

这很简单。

    let address = "1 Infinite Loop, Cupertino, CA 95014"

    let geoCoder = CLGeocoder()
    geoCoder.geocodeAddressString(address) { (placemarks, error) in
        guard
            let placemarks = placemarks,
            let location = placemarks.first?.location
        else {
            // handle no location found
            return
        }

        // Use your location
    }

您还需要添加和导入CoreLocation框架。

Answer 2

你可以使用CLGeocoder，你可以将地址（字符串）转换为坐标，反之亦然，试试这个：

import CoreLocation

var geocoder = CLGeocoder()
geocoder.geocodeAddressString("your address") {
    placemarks, error in
    let placemark = placemarks?.first
    let lat = placemark?.location?.coordinate.latitude
    let lon = placemark?.location?.coordinate.longitude
    print("Lat: \(lat), Lon: \(lon)")
}

Answer 3

这有效

let geocoder = CLGeocoder() 
let address = "8787 Snouffer School Rd, Montgomery Village, MD 20879"
        geocoder.geocodeAddressString(address, completionHandler: {(placemarks, error) -> Void in
            if((error) != nil){
                print("Error", error ?? "")
            }
            if let placemark = placemarks?.first {
                let coordinates:CLLocationCoordinate2D = placemark.location!.coordinate
                print("Lat: \(coordinates.latitude) -- Long: \(coordinates.longitude)")
            }
        })

Answer 4

这是我想出的返回CLLocationCoordinat2D对象的内容：

func getLocation(from address: String, completion: @escaping (_ location: CLLocationCoordinate2D?)-> Void) {
    let geocoder = CLGeocoder()
    geocoder.geocodeAddressString(address) { (placemarks, error) in
        guard let placemarks = placemarks,
        let location = placemarks.first?.location?.coordinate else {
            return
        }
        completion(location)
    }
}

所以，假设我有这个地址：

let address = "Springfield, Illinois"

用法

getLocation(from: address) { location in
    print("Location is", location.debugDescription)
    // Location is Optional(__C.CLLocationCoordinate2D(latitude: 39.799372, longitude: -89.644458))

}
