EGORefreshTableHeaderView

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 
      
}  

 

 最后，自己配置数据源进行测试。
