我在struct
后面遇到了一些麻烦:
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,我得到运行时错误:
说我正在从plist 加载数据时,这很重要。任何人都可以告诉我我做错了什么?

错误非常明确:您正在将字符串类型的值转换为NSNumber
。
请改为尝试:
let latitudeStr = dictionary["Latitude"] as! String
self.latitude = CLLocationDegrees(latitudeStr)!
你也应该对"Longitude"
属性做同样的事情;)
您也可能遇到本地化数字问题。试试这个:
let numberFormatter = NumberFormatter()
numberFormatter.decimalSeparator = ","
numberFormatter.thousandSeparator = "."
...
self.latitude = numberFormatter.number(from: latitudeStr)!.doubleValue
