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()
}

我已尝试String(manager.location.coordinate.latitude)，但这似乎不起作用。

Answer 1

尝试使用格式

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

Answer 2

首先，您必须将其读作double，然后将其转换为字符串。代码应该是这样的。检查语法，我还没有编译代码。

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

Answer 3

你可以尝试这个（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)

如何将CoreLocation坐标转换为String？
