Alamofire 3.5.1坠毁取消上传请求

我只是跟着cnoon's suggest的请求时取消，步骤，如：Alamofire 3.5.1坠毁取消上传请求

发布multipartFormData上传请求;

捕获上传进度并在encodingCompletion中获取Alamofire.Request;

做取消请求;

然后崩溃即将到来。

所有与上传相关的代码如下： private var request：Alamofire.Request？

func upload() { 
     Alamofire.upload(
      .POST, 
      "\(AppManager_Inst.currentServerAddress)/cloud/uploadFile", 
      multipartFormData: { [unowned self] multipartFormData in 

       if self.uploadFile.data.isKindOfClass(UIImage), 
        let image = self.uploadFile.data as? UIImage, 
        let imageData = UIImagePNGRepresentation(image) { 
        multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "\(self.uploadFile.name).png", mimeType: "image/png") 
       } 

       for (key, value) in parameters { 
        multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
       } 

      }, encodingCompletion: { [unowned self] encodingResult in 
       switch encodingResult { 
       case .Success(let upload, _, _): 

        self.request = upload 

        upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in 
         dispatch_async(dispatch_get_main_queue()) { 
          let buffer = ["file": "\(self.uploadFile.id)", "speed": "\(bytesRead)", "readed": "\(totalBytesRead)", "all": "\(totalBytesExpectedToRead)"] 
          GlobalBroadcast_Inst.broadcastMsg(.uploading, msg: buffer) 
         } 
        } 
        upload.responseData(completionHandler: { (response) in 

         self.uploading = false 

         let resp = NewFileResp.parseFromData(response.data!) 
        }) 

       case .Failure(let error): 
        self.uploading = false 
        print(error) 
       } 
      } 
     ) 
    } 

    request?.cancel()

崩溃，信息如下：

有谁可以帮上这个？

我发现我的问题的根本原因是response.data为0字节的NSData，这样的protobuf的parseFromData失败：

upload.responseData(completionHandler: { (response) in 

         self.uploading = false 

         let resp = NewFileResp.parseFromData(response.data!) 
        })
