Ios 从NSArray中提取数据

我的php脚本向我的swift iOS应用程序发送JSON响应，格式如下所示。使用以下代码将其解析为

NSArray

：

让jsonArray=试试NSJSONSerialization.JSONObjectWithData（数据已修复，选项：[]）

我已在swift代码中创建了以下对象：

class Friend : NSObject {
var name: String?
var id: String?
var profile_pic : String?


}


class Message : NSObject {
var id: String?
var text: String?
var date: NSDate?
var sender: Friend?
}

class Chat : NSObject {
var id : String?
var chat_partner : Friend?
var chat_messages : [Message]?
}

我现在要做的是循环遍历下面的

NSArray

，并将数据提取到我的对象实例中，因此简单地说，通过下面的示例，我想创建两个id为1和2的聊天对象，以及所有适当的变量。我不知道如何在swift中正确执行这样的循环

JSON响应：

Array: (
    {
    chatId = 1;
    message =         {
        1 =             {
            chatId = 1;
            "message_id" = 24242241;
            sender = 1233;
            text = "hello i am";
            timestamp = "2016-05-24 17:13:08";
        };
        2 =             {
            chatId = 1;
            "message_id" = 421421;
            sender = 1233;
            text = great;
            timestamp = "2016-05-24 17:15:08";
        };
    };
    "user1_id" = 1233;
    "user1_name" = David;
    "user1_profile_pic" = "http://graph.facebsddsaadsadsook.com/1233/picture?type=large";
    "user2_id" = 8543211123;
    "user2_name" = 0;
    "user2_profile_pic" = "<null>";
},
    {
    chatId = 2;
    "user1_id" = 23413524635;
    "user1_name" = 0;
    "user1_profile_pic" = "<null>";
    "user2_id" = 1233;
    "user2_name" = David;
    "user2_profile_pic" = "http://graph.facebsdadsook.com/1233/picture?type=large";
}
)

数组：(
{
chatId=1；
消息={
1 =             {
chatId=1；
“消息id”=242241；
发送方=1233；
text=“你好，我是”；
timestamp=“2016-05-2417:13:08”；
};
2 =             {
chatId=1；
“消息id”=421421；
发送方=1233；
文字=伟大；
timestamp=“2016-05-2417:15:08”；
};
};
“用户1_id”=1233；
“user1_name”=David；
“用户1_配置文件_图片”=”http://graph.facebsddsaadsadsook.com/1233/picture?type=large";
“用户2_id”=8543211123；
“user2_name”=0；
“user2_profile_pic=”；
},
{
chatId=2；
“用户1_id”=23413524635；
“user1_name”=0；
“user1_profile_pic”=”；
“用户2_id”=1233；

}

var count\u chats=0；
对于jsonArray中的anItem as！[字典]{
让curr_chat=chat（）
如果让chatId=anItem[“chatId”]作为字符串{
curr\u chat.id=chatId
}
让朋友=朋友
让user1id=anItem[“user1\u id”]作为！字符串
让user2id=anItem[“user2_id”]作为！字符串
if（user1id==userID）{
如果让user2id=anItem[“user2_id”]作为字符串{
friend.id=user2id
}
如果让user2name=anItem[“user2_name”]作为字符串{
friend.name=user2name
}
如果让user2profilepic=anItem[“user2\u profile\u pic”]作为？字符串{
friend.profile\u pic=user2profilepic
}
}
else if（user2id==userID）{
如果让user1id=anItem[“user1\u id”]作为字符串{
friend.id=user1id
}
如果让user1name=anItem[“user1_name”]作为字符串{
friend.name=user1name
}
如果让user1profilepic=anItem[“user1\u profile\u pic”]作为字符串{
friend.profile\u pic=user1profilepic
}
}
打印（“通过”）
curr\u chat.chat\u partner=朋友
var chat_messages:[消息]？=nil
var count_messages=0；
如果让dataArray=anItem[“message”]作为NSArray{
用于dataArray中的onemessage as！[字典]{
让curr_message=message（）
如果让messageid=onemessage[“message_id”]作为？字符串{
curr_message.id=messageid
}
如果让messagedate=onemessage[“timestamp”]作为？NSDate{
curr_message.date=messagedate
}
如果让messagesender=onemessage[“sender”]作为？字符串{
curr_message.sender=messagesender
}
如果让messagetext=onemessage[“text”]作为字符串{
curr_message.text=messagetext
}
聊天信息！[count\u messages]=当前信息
count_messages=count_messages+1
}
}
curr\u chat.chat\u messages=聊天信息
self.user\u chats！[count\u chats]=curr\u chat
count\u chats=count\u chats+1

不是答案，但这可能会对您有所帮助，在编写类似以下内容时，您应该检查您的属性是否为零：

curr\u message.id=onemessage[“chatId”]as！String

。 您可以做什么：

if let chatId = onemessage["chatId"] as? String {
   curr_message.id = chatId
}

或者，如果您希望它更简单，您可以使用和编写以下内容：

curr\u message.id=onemessage[“chatId”]。stringValue

希望这能对你有所帮助！

我真的不知道这是否真的能帮助到某人，但我已经被这封邮件屏蔽了3天。我终于看到了这个问题，这个问题就是我的答案，感谢@Alk。简而言之，我在处理这类数据（NSArray）：

所以试试看，JSON中的数据将以type

AnyObject

的形式输入。您需要将其转换为type[NSDictionary]。

[<__NSArrayM 0x6000000556e0>(
{
    author = Julioenred;
    id = 1;
    text = "hello world";
},
{
    author = Pepe;
    text = "Saludos!!";
}
)
]

for i in data.first as! [Dictionary<String, AnyObject>] {
    let message = Message(message: "", user: "")
    if let author = i["author"] as? String {
       message.author = author
    }
    if let text = i["text"] as? String {
       message.text = text
    }
 }

import Foundation

class Message: Mappable {
    var author: String? = ""
    var text: String? = ""
    
    init(message: String, user: String) {
        self.author = user
        self.text = message
    }
}
