ObjectMapper

• 將String轉成Date

  • 先實作出遵循 TransformType 這個protocol的class

  open class StringTransform:TransformType {
  
      public typealias Object = Date
      public typealias JSON = String
  
      public init() {}
  
      open func transformFromJSON(_ value: Any?) -> Date? {
  
          let formatter = DateFormatter()
          formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
  
          if let dateString = value as? String {
              return formatter.date(from: dateString)
          }
          return nil
      }
  
      open func transformToJSON(_ value: Date?) -> String? {
  
          let formatter = DateFormatter()
          formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
  
          if let date = value {
              return formatter.string(from: date)
          }
          return nil
      }
  }
  

  • 然後在Mapping的時候調用

      mutating func mapping(map: Map) {
          date <- (map["date"], StringTransform())
      }
