实现多数据+多图片混合上传到话，写个for语句就好比如：

for(int i=0;i<图片流数组.count;i++){                NSData *dicImage = (NSData *)[[图片流数组] objectAtIndex:i];                [imgbody appendFormat:@"%@\r\n",MPboundary];                                [imgbody appendFormat:@"Content-Disposition: form-data; name=\"file_data\"; filename=\"哈哈.jpg\"\r\n"];                                //声明上传文件的格式                                [imgbody appendFormat:@"Content-Type: image/jpeg; charset=utf-8\r\n\r\n"];                                                //将body字符串转化为UTF8格式的二进制                                [myRequestData appendData:[imgbody dataUsingEncoding:NSUTF8StringEncoding]];                                //将image的data加入                                [myRequestData appendData:dicImage];                                [myRequestData appendData:[ @"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];            }
