json - 从 JSON API 下载 Alamofire

Question

我试图通过 api 在标签上设置文本，但似乎甚至没有调用该函数。请引用下面的片段。有什么问题吗？

编辑:typealias DownloadComplete = () -> ()

var date: String = ""

override func viewDidLoad() {
    super.viewDidLoad()

    timeLbl.text = date

    // Do any additional setup after loading the view.
}

func downloadTimeData(completed: @escaping DownloadComplete) {
    //Downloading forecast weather data for TableView
    Alamofire.request(APIURL).responseJSON { response in

        let result = response.result

        if let dict = result.value as? Dictionary<String, AnyObject> {
            if let currentDate = dict["fulldate"] as? String {
                self.date = currentDate
                print(self.date)
                print("xxx")
            }
        }
     completed()
    }
}

我通过 alamofire 文档找到了更简单、更容易的方法。

override func viewDidLoad() {
    super.viewDidLoad()

    Alamofire.request(APIURL).responseJSON { response in
        print(response.result)   // result of response serialization
        let result = response.result

        if let dict = result.value as? Dictionary<String, AnyObject> {
            let currentDate = dict["fulldate"] as? String
            self.timeLbl.text = currentDate
            }

    }
}
