xcode - 如何在 Xcode 中将 CLLocation 转换为字符串

Question

我使用 SwiftLocation 获取坐标:

try! SwiftLocation.shared.currentLocation(Accuracy.House, timeout: 20, onSuccess: { (location) -> Void in
    print(location?.description)            
         }) { (error) -> Void in
    print("something went wrong")
         }

在位置？.描述我明白了:

<+37.78583400,-122.40641700> +/- 5.00m (speed -1.00 mps / course -1.00) @ 2/22/16, 6:35:55 PM Indochina Time

我只需要获取坐标。所以我为它循环:

    while name.characters.last != ">" { // delete all after ">"
        name = String(name.characters.dropLast())
    }
    name = String(name.characters.dropLast()) // delete ">"
    name = String(name.characters.dropFirst()) // delete "<"
    name = String(name.characters.dropFirst()) // delete "+"
    print(name) // get 37.78583400,-122.40641700
    tempMyLat = name
    while tempMyLat.characters.last != "," { // delete all after ","
        tempMyLat = String(tempMyLat.characters.dropLast())
    }
    tempMyLon = name
    while tempMyLon.characters.first != "," { // delete all before ","
        tempMyLon = String(tempMyLon.characters.dropFirst())
    }
    tempMyLon = String(tempMyLon.characters.dropFirst()) // delete ","

但此代码仅适用于字符串。当我得到 location?.description - 我无法将它转换为类型 - 字符串，因为“location”是 CLLocation 类型。

那么，我的问题是:如何将 location?.description 转换为 String ？ 或者 如何仅从 SwiftLocation 获取坐标

谢谢。

在 Xcode 10+ 和 Swift 3 中，您可能必须执行类似于以下操作的操作:

let myLocation: CLLocation = locations[0] as CLLocations
var myLatitude: String = String(format: "%f", myLocation.coordinate.latitude)
var myLongitude: String = String(format:"%f", myLocation.coordinate.longitude)
