Convert address to coordinates swift
提问by Paul Bénéteau
How can I convert a Stringaddress to CLLocationcoordinates with Swift? I have no code yet, I looked for a solution but I didn't find anyone yet.
如何使用 Swift将String地址转换为CLLocation坐标？我还没有代码，我寻找了一个解决方案，但我还没有找到任何人。
Thanks.
谢谢。

This is pretty easy.
这很容易。
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
}
You will also need to add and import CoreLocation framework.
您还需要添加和导入 CoreLocation 框架。

You can use CLGeocoder, you can convert address(string) to coordinate and you vice versa, try this:
您可以使用 CLGeocoder，您可以将地址（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)")
}

Here's what I came up with to return a CLLocationCoordinat2Dobject:
这是我想出的返回CLLocationCoordinat2D对象的方法：
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 {
completion(nil)
return
}
completion(location)
}
}
So let's say I've got this address:
所以假设我有这个地址：
let address = "Springfield, Illinois"
Usage
用法
getLocation(from: address) { location in
print("Location is", location.debugDescription)
// Location is Optional(__C.CLLocationCoordinate2D(latitude: 39.799372, longitude: -89.644458))
}

This works
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)")
}
})

Swift 5 and Swift 5.1
Swift 5 和 Swift 5.1
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)")
}
