swift - 当为具有符合自定义类的成员的对象设置值时，类不符合键的键值编码

Question

我正在尝试在一个对象上使用 setValuesForKeys，该对象的成员符合自定义类，这就是为什么我相信我会收到以下错误，我该如何解决这个问题？如果简单的话，我更喜欢以 native 方式执行此操作，或者我可以使用任何库/框架来解决此问题。

this class is not key value coding-compliant for the key availabilityTimesDict

func convertJSONDataToSwiftObject(){

    let registrationDataDict =
        [
            "firstName": "Joe Bloggs",
            "alternateNames": ["Joe", "Bloggs"],

            "availabilityTimesDict" : [
                "Friday" : ["times":[["startTime":"9:00 AM","endTime":"1:30 PM"],["startTime":"2:30 PM","endTime":"6:00 PM"]],"weekday":"Friday","available":true],
                "Monday" : ["times":[["startTime":"11:00 AM","endTime":"1:30 PM"]], "weekday":"Monday","available":true]]
        ] as [String : AnyObject]

    var profileDetailsObject = ProfileDetails()

    profileDetailsObject.setValuesForKeys(registrationDataDict as [String : AnyObject])  // SOURCE OF ERROR

}


class ProfileDetails: NSObject{

    var firstName              :   String!
    var alternateNames         :   [String]!
    var availabilityTimesDict  :   [String : AvailabilityTimes.DailyTimes]!
}

class AvailabilityTimes: NSObject{
    struct Times{
        var startTime : String?
        var endTime   : String?

        func convertToDictionary() -> Dictionary<String, Any> {
            return [
                "startTime" : self.startTime as Any,
                "endTime"   : self.endTime as Any
            ]
        }
    }

    struct DailyTimes{
        let weekday : String
        var available : Bool
        var times = [Times]()
        mutating func update(times: [Times]){
            self.times = times
        }

        func convertToDictionary() -> Dictionary<String, Any> {
            return [
                "weekday"   : self.weekday,
                "available" : self.available,
                "times"     : self.times.map{$0.convertToDictionary()}
            ]
        }

    }
}

KVO 很复杂，

我可以清楚地看到错误是 "availabilityTimesDict":

您可以使用来自 kvo dict 的评论 availabilityTimesDict 检查它

如果你使用 initalizer 而不是 KVO 会更好更可读，如果有任何变化，它在未来也会有帮助你可以轻松地做一些修改

这里是示例代码

class ProfileDetails: NSObject{

var firstName              :   String!
var alternateNames         :   [String]!
var availabilityTimesDict  :   [String : AvailabilityTimes.DailyTimes]!

private override init() {
     super.init()
}

required init(with FirstName : String,alterName:[String],availabilityTimesDict:[String : AvailabilityTimes.DailyTimes]) {
    super.init()
    self.firstName = FirstName;
    self.alternateNames = alterName;
    self.availabilityTimesDict = availabilityTimesDict;

}
}

class AvailabilityTimes: NSObject{
    struct Times{
        var startTime : String?
        var endTime   : String?

        func convertToDictionary() -> Dictionary<String, Any> {
            return [
                "startTime" : self.startTime as Any,
                "endTime"   : self.endTime as Any
            ]
        }
    }

    struct DailyTimes{
        let weekday : String
        var available : Bool
        var times = [Times]()
        mutating func update(times: [Times]){
            self.times = times
        }

        func convertToDictionary() -> Dictionary<String, Any> {
            return [
                "weekday"   : self.weekday,
                "available" : self.available,
                "times"     : self.times.map{$0.convertToDictionary()}
            ]
        }

    }
}

var availTimes = AvailabilityTimes.Times.init(startTime: "9:00 AM", endTime: "1:30 PM")
var avaiblityTimes = AvailabilityTimes.DailyTimes.init(weekday: "Friday", available: true, times:[availTimes] )

var times = ["Firday":avaiblityTimes]

var profileDetailsObject = ProfileDetails.init(with: "Joe Bloggs", alterName: ["Joe", "Bloggs"], availabilityTimesDict: times)
profileDetailsObject.firstName = "test"
