Ios 如何将[JSON]转换为数据格式（Encode），以便将其与模型绑定

我有[JSON]数组格式的数据，我需要基于JSON创建模型并需要绑定它们

我试图对[JSON]进行编码，但应用程序因错误消息而崩溃

由于未捕获异常而终止应用程序 “NSInvalidArgumentException”，原因：“JSON写入中的类型无效。” （uu SwiftValue）'

我已经基于JSON数据创建了一个模型，并希望将它们与[JSON]数组值绑定

JSON是

基于模型的结构

struct Tzlstate: Codable {
    var tzlLightStatus: TzlLightStatus?
    var updateTimestamp: String?
    var tzlColorSettings: TzlColorSetting?
    var tzlConfiguration: TzlConfiguration?
}
struct TzlColorSetting: Codable {
    var tzlColors: [TzlColor]?
}

struct TzlConfiguration: Codable {
    var tzlGroupStates: [TzlGroupState]?
    var tzlZoneFunctions: [TzlZoneFunction]?
}
struct TzlColor: Codable {
    var red: Int?
    var blue: Int?
    var colorId: Int?
    var secondary: Bool?
    var green: Int?
}
struct TzlLightStatus: Codable {
    var tzlZones: [TzlZone]?
}
struct TzlZone: Codable {
    var state: String?
    var red: Int?
    var green: Int?
    var zoneId: String?
    var intensity: Int?
    var speed: Int?
    var blue: Int?
}
struct TzlZoneFunction: Codable {
    var zoneId: String?
    var zoneFunction: String?

struct TzlGroupState: Codable {
    var state: String?
    var groupId: String?
}

用

Tzlstate

class/struct定义更新你的问题。你把

SwiftyJSON

和

Codable

搞混了。只使用后者。不要在解码错误捕获块中打印本地化描述。打印

错误

实例。它会准确地告诉您出了什么问题。@Soroush我解决了崩溃问题，但现在我遇到了一个错误，无法读取数据，因为它的格式不正确。@vadian是的，现在我只使用Codable。并使用let jsonEncoder=jsonEncoder（）jsonEncoder.outputFormatting=.prettyPrinted let jsonData=try解决崩溃问题？jsonecoder.encode（m_Tzlstates）。但现在出现错误，无法读取数据，因为它的格式不正确format@Soroush感谢您现在的响应，让tzlstate=try JSONDecoder（）.decode（[tzlstate.self]，from:data）之后，它工作正常。谢谢你的回复
