ios - 如何将另一个数组中的数组存储到 Swift 中从 JSON 传递的全局变量？

Question

我有一个 JSON，它从 API 调用接收数组

该数组中还有另外 3 个数组:

userDetails、userStats、社区

此 API 调用的示例如下:

["communities": <__NSArrayI 0x6000002540a0>(
{
id = 5;
name = South;
},
{
id = 13;
name = HurraHarry;
},
{
id = 15;
name = EnclliffeT;
}
)
, "userStats": {
totalDraws = 3;
totalLosses = 10;
totalWins = 1;
}, "userDetails": {
id = 31;
"user_email" = "steve@gmail.com";
"user_name" = "Steve Base";
}]

我想将数组 userStats 存储在一个可以传递给另一个 VC 的变量中。

我的类中有一个全局变量 var userStatsArray = [AnyObject]()

以下代码处理 JSON:

 let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? [String:AnyObject]
                  print (json!)

                  if let arr = json?["communities"] as? [[String:String]] {
                        self.communitiesArray = arr.flatMap { $0["name"]!}
                        self.communityIdsArray = arr.flatMap { $0["id"]!}

                    }

                    if let dict = json?["userDetails"] as? [String:String] {
                      self.tempPlayerId = [dict["id"]!]
                        let characterArray = self.tempPlayerId.flatMap { String.CharacterView($0) }
                        let newPlayerId = String(characterArray)
                        self.playerId = newPlayerId
                    }
                    if  let tempArray = json?["userStats"] as? [String:AnyObject]{
                        print ("here ", tempArray)

                    }

打印命令成功打印 userStats 数组及其所有 header (totalWins、totalDraws、totalLosses...) -

如何将此数组存储到我的全局变量 var userStatsArray = [AnyObject]() 中，以便我可以将其传递给另一个 VC？

最好创建一个像这样的自定义类，并使用该自定义类类型声明数组。然后将 userStats 对象转换为自定义类类型。

class userStats: NSObject {

var totalDraws: NSNumber?
var totalLosses: NSNumber?
var totalWins: NSNumber?

    init(totalDraws: NSNumber?, totalLosses: NSNumber?, totalWins: NSNumber?) {
        self.totalDraws = totalDraws
        self.totalWins = totalWins
        self.totalLosses = totalLosses
    }

}

var userStatsArray = [userStats]()

//像这样更改您的代码

let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? [String:AnyObject]
              print (json!)

              if let arr = json?["communities"] as? [[String:String]] {
                    self.communitiesArray = arr.flatMap { $0["name"]!}
                    self.communityIdsArray = arr.flatMap { $0["id"]!}

                }

                if let dict = json?["userDetails"] as? [String:String] {
                  self.tempPlayerId = [dict["id"]!]
                    let characterArray = self.tempPlayerId.flatMap { String.CharacterView($0) }
                    let newPlayerId = String(characterArray)
                    self.playerId = newPlayerId
                }
                if  let tempArray = json?["userStats"]as? userStats {

                    userSytatsArray.append(tempArray)
                }
