swift - 无法将类型 '(NSURLRequest, HTTPURLResponse?, AnyObject?, NSError?) -> Void' 的值转换为预期的参数类型 '(DataResponse) -> Void'

Question

我在 codingforentrepreneurs.com 学习如何制作 iOS 应用

现在我在研究 Alamofire。 Xcode 是 8.3.3

这是错误命令。我不明白错误命令。

Cannot convert value of type '(NSURLRequest, HTTPURLResponse?, AnyObject?, NSError?) -> Void' to expected argument type '(DataResponse) -> Void'

这是 ViewController.swift

import UIKit
import Alamofire

    class ViewController: UIViewController {

        override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            var rTest = Alamofire.request("http://ec2-52-78-193-10.ap-northeast-2.compute.amazonaws.com", method: .get)
            .responseJSON(completionHandler: isComplete)
        }

        func isComplete(request:NSURLRequest, response: HTTPURLResponse?, data: AnyObject?, error:NSError?) -> Void {
            print(response!.statusCode)
            print(data)
            print(error)
            print(request)

        }

        override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }


    }

我不知道是什么问题。你能帮帮我吗？

完成处理程序方法的签名应该是这样的。

func isComplete(response: DataResponse<Any>) {
    let statusCode = response?.response?.statusCode
    let result = response?.result
    let request = response?.request
}
