Question

我想使用ObjectMapper在单例情况下解析Json字符串。示例代码：

class User: Mappable {

    var username: String?
    var signature: String?

    //Singleton
    static let shared = User()
    private init() {}

    //Mappable functions
    required init?(map: Map) {}

    func mapping(map: Map) {
        username <- map["username"]
        signature <- map["signature"]
    }

    //Update userInfo after network request
    func getUserInfo() {
        //Network things
        ...
        //Example data
        let data = [
            "username": "Eason",
            "signature": "I love U"
        ]

        //Some thing like this to update userInfo
        Mapper<User>().map(data)
    } 

}

那么，在单例情况下使用ObjectMapper的正确方法是什么？

Answer 1

我更喜欢以下选项。

1）UserManager（单个）：

Bet.Events["one"]

2）用户模型：

Bet.Events["one"] = Event{
    Name: "first",
    Runners: make(map[int]Runner),
}

3）RestClient

class UserManager: NSObject {

    static let shared = UserManager()

    var profile: UserProfile?

    private override init() {}

    func loadUserProfile(completion: @escaping () -> ()) {

        RestClient.shared.getUserProfile() { [weak self] (profile, error) in

            guard let `self` = self else { return }

            self.profile = profile as? UserProfile

            completion()
        }
    }
}

Swift使用ObjectMapper和singleton
