1、下載EGORefreshTableHeaderView開源框架。

2、往應用中添加EGORefreshTableHeaderView.h文件、EGORefreshTableHeaderView.m文件、Resource目錄，并且導入QuartzCore.framework

3、添加代碼

?往tableview對應的類的頭文件中添加如下代碼 EGORefreshTableHeaderView *_refreshHeaderView;

Java代碼??

????BOOL?_reloading;??

??

-?(void)reloadTableViewDataSource;??

-?(void)doneLoadingTableViewData;??

?往viewDidLoad函數里添加如下代碼

Java代碼??

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];??

??再添加一些事件函數

C代碼??

#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，自己配置數據源進行測試。
