iOS批量上传图片

这是使用

// =======================3.x调用
 
    [AFHTTPSessionManager startMultiPartUploadTaskWithURL:CreateOrder_URL
                                              imagesArray:self.imageDataArr
                                        parameterOfimages:@"filename"

        DLog(@"-----上传完成-----");
      
    } failedBlock:^(id  _Nonnull operation, NSError * _Nonnull error) {
       DLog(@"-------失败------");
    } uploadProgressBlock:^(float uploadPercent, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
        DLog(@"---上传百分比%f\n", uploadPercent);

    }];
//=======================2.x 版本
     [AFHTTPRequestOperationManager startMultiPartUploadTaskWithURL:UpImgArr_URL
                                                       imagesArray:self.imageDataArr

                                                  compressionRatio:0.5
                                                      succeedBlock:^(id  _Nonnull operation, id  _Nonnull responseObject) {

                                                          //   上传全部完成 
                                                          
                                                      } failedBlock:^(id  _Nonnull operation, NSError * _Nonnull error) {
     //                                                          失败
          
                                                      } uploadProgressBlock:^(float uploadPercent, long long totalBytesWritten, long long totalBytesExpectedToWrite) {

                                                      }];

把方法放在 AFHTTPSessionManager 中 af 3.x版本 这个版本

把这个方法放在 afnetworking的 AFHTTPRequestOperationManager 类中 如果你用的是2.X版本
