ObjectMapper - 初始化对象IOS

Question

让我头疼的简单事情 - 如何初始化符合可映射协议的对象,还没有任何JSON.

我想做的是简单地在代码中初始化空的User对象,如下所示:

let user = User()

但是这给了我错误:"在调用中缺少参数#1的参数"

我能够使用swift 1.2在版本0.14中完成它,但现在它无法正常工作.你们现在知道如何在swift 2和新的Object Mapper中做到这一点吗？(我知道如何使用json等初始化它,我只是想为其他目的初始化该对象,我无法弄清楚如何)

class User: Mappable {
var username: String?
var age: Int?
var weight: Double!
var array: [AnyObject]?
var dictionary: [String : AnyObject] = [:]
var bestFriend: User?                       // Nested User object
var friends: [User]?                        // Array of Users
var birthday: NSDate?

required init?(_ map: Map) {

}

// Mappable
func mapping(map: Map) {
    username    <- map["username"]
    age         <- map["age"]
    weight      <- map["weight"]
    array       <- map["arr"]
    dictionary  <- map["dict"]
    bestFriend  <- map["best_friend"]
    friends     <- map["friends"]
    birthday    <- (map["birthday"], DateTransform())
}
}

请帮忙!

Answer 1

以下应该有效:

class User: NSObject, Mappable {
var username: String?
var age: Int?
var weight: Double!
var array: [AnyObject]?
var dictionary: [String : AnyObject] = [:]
var bestFriend: User?                       // Nested User object
var friends: [User]?                        // Array of Users
var birthday: NSDate?

override init() {
    super.init()
}

convenience required init?(_ map: Map) {
    self.init()
}

// Mappable
func mapping(map: Map) {
    username    <- map["username"]
    age         <- map["age"]
    weight      <- map["weight"]
    array       <- map["arr"]
    dictionary  <- map["dict"]
    bestFriend  <- map["best_friend"]
    friends     <- map["friends"]
    birthday    <- (map["birthday"], DateTransform())
}
}

上述答案的固定版本:

init() {}
required convenience init?(_ map: Map) { self.init() }
