如何将 CoreLocation 坐标转换为字符串？

Question

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var user_lat = manager.location.coordinate.latitude
    var user_long = manager.location.coordinate.longitude
    self.locationManager.stopUpdatingLocation()
}

我试过了String(manager.location.coordinate.latitude)，但好像不行。

Answer 1

首先，您必须将其读取为double，然后将其转换为string。代码应该是这样的。检查语法，我没有编译代码。

let lat: Double = manager.location.coordinate.latitude
let user_lat : String = String(format:"%f", lat)

Answer 2

试试格式

let user_lat = String(format: "%f", manager.location.coordinate.latitude)
let user_long = String(format: "%f", manager.location.coordinate.longitude)

Answer 3

你可以试试这个 (Swift 3)

guard let newLocation = locations.last else { return }

let latitude = Double(newLocation.coordinate.latitude)
let longitude = Double(newLocation.coordinate.longitude)

let latString = (latitude < 0) ? "S" : "N"
let lonString = (longitude < 0) ? "W" : "E"

let coords = "\(latString) \(latitude) \(lonString) \(longitude)"

print(coords)
