在需要上传图片的界面使用如下代码调用该上传类：使用时根据需要进行相应调整就可以。


[SVProgressHUD showWithStatus:@"上传中，请稍候..." maskType:SVProgressHUDMaskTypeClear];    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{        NSMutableDictionary * dir=[NSMutableDictionary dictionaryWithCapacity:7];       //像字典添加除图片之外的相关参数        [dir setValue:@"0" forKey:@"longitude"];        [dir setValue:@"0" forKey:@"latitude"];                 NSString *url = [NSString stringWithFormat:@"%@ShopManage-addStore",OA_DOMAIN];        NSLog(@"有图片上传");
//self.pathArray存储要被上传的图片的路径，self.nameArray存储要被上传的图片的名称        [PicUpload postRequestWithURL:url postParems:dir picFilePath:self.pathArray picFileName:self.nameArray];    });
