记录下自己总结的刷新方法，免得忘记了....

-(void)getDataWithHead:(BOOL)isHead{
    if (isHead) {
        page = 1;
    }else{
        if (page < 2) {
            page = 2;
        }
    }
    [GPAFNetworking3 get:[NSString stringWithFormat:@"%@?articleId=%ld&source=toyohuApp&site=QA&page=%ld",GetCommunityComment,(long)_caId,(long)page] progress:^(NSProgress * _Nonnull progress) {
        
    } success:^(id  _Nullable responseObject) {
        
        
        if ([[responseObject objectForKey:@"code"] integerValue] != 1) {
            SHOW_ERROR
        }else{
            MyCommentMyComment*base = [[MyCommentMyComment alloc]initWithDictionary:responseObject];
            
            if (base.msg.comment.count){
                if (isHead) {
                    [QAArray removeAllObjects];
                }else{
                    page ++;
                }
                [QAArray addObjectsFromArray: base.msg.comment];
            }else{
                [(MJRefreshAutoGifFooter *)myTableView.mj_footer setTitle:@"空空如也" forState:MJRefreshStateIdle];
            }
            
            [myTableView reloadData];
        }
        if (isHead) {
            [myTableView.mj_header endRefreshing];
        }else{
            dispatch_async(dispatch_get_main_queue(), ^{
                [myTableView.mj_footer endRefreshing];
                
            });
        }
        
    } failure:^(NSString * _Nonnull errorLD) {
        SHOW_NTERROR
        if (isHead) {
            [myTableView.mj_header endRefreshing];
        }else{
            dispatch_async(dispatch_get_main_queue(), ^{
                [myTableView.mj_footer endRefreshing];
                
            });
        }
    }];
    
}

使用：

• 头刷新：

-(void)LoadNewData
{
    [self getDataWithHead:YES];
}

• 尾刷新：

-(void)loadMoreData
{
    [self getDataWithHead:NO];
}
