如何將CoreLocation座標轉換爲字符串？

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() 
} 

我試過String(manager.location.coordinate.latitude)但這似乎並不奏效。

Answer 1

與格式

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

Answer 2

首先，您必須將它讀取爲double，然後將其轉換爲字符串。代碼應該是這樣的。檢查語法，我沒有編譯代碼。

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

Answer 3

你可以試試這個（SWIFT 3）嘗試

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)
