无法从 plist 读取 CLLocationDegrees

Question

我遇到了一些问题 struct:

struct EmployeeDetails {
    let functionary: String
    let imageFace: String
    let phone: String
    let latitude: CLLocationDegrees
    let longitude: CLLocationDegrees

    init(dictionary: [String: Any]) {
        self.functionary = (dictionary["Functionary"] as? String) ?? ""
        self.imageFace = (dictionary["ImageFace"] as? String) ?? ""
        self.phone = (dictionary["Phone"] as? String) ?? ""
        self.latitude = (dictionary["Latitude"] as! CLLocationDegrees)
        self.longitude = (dictionary["Longitude"] as! CLLocationDegrees)

我没有编译错误但是，当我运行应用程序时，我得到这个运行时间错误：

重要的是要说我正在从 plist 加载数据。谁能告诉我我做错了什么？

编辑：

现在我遇到了这些错误：

Answer 1

错误很明显：您正在将字符串类型的值转换为 NSNumber。

试试这个：

let latitudeStr = dictionary["Latitude"] as! String
self.latitude = CLLocationDegrees(latitudeStr)!

你也应该对 "Longitude" 属性做同样的事情 ;)

您也可能运行遇到 本地化号码 问题。试试这个：

let numberFormatter = NumberFormatter()
numberFormatter.decimalSeparator = ","
numberFormatter.thousandSeparator = "."
...
self.latitude = numberFormatter.number(from: latitudeStr)!.doubleValue
