无法将'__NSArrayI'(0x10df73c08)类型的值转换为'NSDictionary'(0x10df74108)

Question

    let url = "http://xyz/index_main.php?c=webservices&a=get&e=007"

    Alamofire.request(url, method: .post, parameters: nil, encoding: JSONEncoding.default)
        .responseJSON { response in
            print(response)
            //to get status code
            if let status = response.response?.statusCode {
                switch(status){
                case 201:
                    print("example success")
                default:
                    print("error with response status: \(status)")
                }
            }
            //to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

结果:

    {
    "create_by" = 007;
    "create_date" = "2016/06/20";
    "due_date" = "2016/06/22";
    "estimate_time" = "";
    fixer = 007;
    priority = High;
    "project_code" = testing;
    status = "Re-Open";
    "task_id" = 228;
    "task_title" = test;
    tester = 007;
},
    {
    "create_by" = 006;
    "create_date" = "2016/06/23";
    "due_date" = "2016/06/24";
    "estimate_time" = "";
    fixer = 007;
    priority = Critical;
    "project_code" = "tanteida.c";
    status = "In Progress";
    "task_id" = 234;
    "task_title" = testing;
    tester = 006;
}

我想转换为NSDictionary并获得不同的数组像task_id(数组)但我收到此错误:

"无法将类型'__NSArrayI'的值转换为NSDictionary"

请帮我

先感谢您

您的回答是Array的Dictionary没有Dictionary,所以如果你想要的所有词典中,你可以使用循环访问它.

if let array = response.result.value as? [[String: Any]] {
    //If you want array of task id you can try like
    let taskArray = array.flatMap { $0["task_id"] as? String }
    print(taskArray)
}
