Ios 如何在调用AlamoFire的POST函数时使用完成处理程序？

我很熟悉通常在.response或之后使用alamofire函数。响应类似于或类似于：

func checkInLocation (accessToken: String, id: Int, latitude: Double, radius: Double, longitude: Double, completionHandler: String) {

  let headers = [

    "Authorization": "bearer \(accessToken)",
    "Cache-Control": "no-cache",
    "Content-Type": "application/json"
  ]

  let parameters: [String: AnyObject] = [
    "id" : id,
    "latitude": latitude,
    "radius": radius,
    "longitude":longitude,
    "languageCulture": "en"
  ]

  Alamofire.request(.POST, "\(baseApiUrl)members/\(id)/checkin", parameters: parameters, encoding: .JSON, headers: headers)
    .responseJSON(completionHandler: { response in

      if((response.result.value) != nil) {

        let swiftyJsonVar = JSON(response.result.value!)

        print("This is the checkin response:\(swiftyJsonVar)")
      }
  })
}

我试图从函数调用中获取它，如下所示：

   checkInLocation(userInfo.sharedInstance.getAccessToken(), id: userInfo.sharedInstance.getMemberID()!, latitude: currentUserLatitude!, radius: 0.3, longitude: currentUserLongitude!, completionHandler: {

      //get JSON response data here

      })

您可以参考下面的内容来更新代码（查看注释以获取解释）

并调用该函数

checkInLocation(String, id: Int, latitude: Double, radius: Double, longitude: Double) { (json) in
   //
}

---

所以有什么问题

func checkInLocation（accessToken:String，id:Int，纬度：Double，半径：Double，经度：Double，completionHandler:Response->Void）

checkInLocation(String, id: Int, latitude: Double, radius: Double, longitude: Double) { (json) in
   //
}
