EGORefreshTableHeaderView学习

1、下载EGORefreshTableHeaderView开源框架。

2、往应用中添加EGORefreshTableHeaderView.h文件、EGORefreshTableHeaderView.m文件、Resource目录，并且导入QuartzCore.framework（憨豆注：不导入Resource和QuartzCore.framework行不行？我看别的教程都没有导入）

3、添加代码

 往tableview对应的类的头文件中添加如下代码 EGORefreshTableHeaderView *_refreshHeaderView;

 往viewDidLoad函数里添加如下代码

if (_refreshHeaderView == nil) { 

           

        EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.view.frame.size.width, self.tableView.bounds.size.height)]; 

        view.delegate = self; 

        [self.tableView addSubview:view]; 

        _refreshHeaderView = view; 

        [view release]; 

           

    } 

       

    //  update the last update date 

    [_refreshHeaderView refreshLastUpdatedDate]; 

 

  再添加一些事件函数

#pragma mark - 

#pragma mark Data Source Loading / Reloading Methods 

   

- (void)reloadTableViewDataSource{ 

       

    //  should be calling your tableviews data source model to reload 

    //  put here just for demo 

    _reloading = YES; 

       

} 

   

- (void)doneLoadingTableViewData{ 

       

    //  model should call this when its done loading 

    _reloading = NO; 

    [_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView]; 

       

} 

   

#pragma mark - 

#pragma mark UIScrollViewDelegate Methods 

   

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{ 

       

    [_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView]; 

       

} 

   

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{ 

       

    [_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView]; 

       

} 

   

#pragma mark - 

#pragma mark EGORefreshTableHeaderDelegate Methods 

   

- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{ 

       

    [self reloadTableViewDataSource]; 

    [self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0]; 

       

} 

   

- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{ 

       

    return _reloading;// should return if data source model is reloading 

       

} 

   

- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{ 

       

    return [NSDate date]; // should return date data source was last changed 

       

}
