kCLErrorDomain iOS 请求中断 sock=client heroku

Question

我有一个使用 django 托管在 heroku 上的后端，并且我有一个 iOS 应用使用那个 api。有时应用程序会抛出此错误

locman err:  Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"

同一请求的后端抛出此错误

sock=client at=error code=H18 desc="Request Interrupted" status=503

我应该如何在 iOS 中处理这个问题？好像是app的问题。我只是一次发送了太多请求吗？这是我的 api 控制器的样子

class func getPictures(location_id: String, completionHandler:( cardImageArray: [CardImage] )->() ){


    var bodyString: String = "location_id=\(location_id)"
    bodyString = bodyString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!


    let url: NSURL = NSURL(string: BASE_URL + "/api/v1/get_pictures" + "?" + bodyString)!

    let req: NSMutableURLRequest = NSMutableURLRequest(URL: url)
    req.HTTPMethod = "GET"
    //req.HTTPBody = bodyString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)

    NSURLConnection.sendAsynchronousRequest(
        req,
        queue: NSOperationQueue.mainQueue())
        { (res: NSURLResponse!, data: NSData! , err: NSError!) -> Void in
            let jsonDict = JSON(data: data, options: NSJSONReadingOptions.AllowFragments, error: nil)

            if (jsonDict["response"].int == 1){

                var cardImageArray: [CardImage] = []

                if let photo_urls = jsonDict["photo_urls"].array{

                    //                        NSString(data: data, encoding: nil)

                    for photo_url_raw in photo_urls{

                        if let url_string = photo_url_raw.string{
                            let ci = CardImage(urlstring: url_string)
                            cardImageArray.append(ci)
                        }


                    }

                    return completionHandler(cardImageArray: cardImageArray)

                }


            }else{

                println("error in get pictures")

                if let errorMessage = jsonDict["error"].string{
                    return
                }

            }
    }
}
