1.

//下拉刷新
    EGORefreshTableHeaderView *refreshHeaderView;
    BOOL egoLoading;

2.

//下拉刷新
    if (refreshHeaderView == nil) {
        //初始化下拉刷新组件
//        EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, -320.0f, self.view.frame.size.width, 320)];
        EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableBulletin.bounds.size.height, self.view.frame.size.width, self.tableBulletin.bounds.size.height)];
        
        view.delegate = self;//设置委托
        //添加下拉刷新控件
        [self.tableBulletin addSubview:view];
        refreshHeaderView = view;
    }
    //update the last updae date
    [refreshHeaderView refreshLastUpdatedDate];
