下拉+上拉刷新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

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 

       

}
