第一步将EGORefreshTableHeaderView.h、EGORefreshTableHeaderView.m两个文件，以及Enormego提供的那一套图片包拖进你的工程里。
第二步

RootViewController.h添加相应的元素：

#import "EGORefreshTableHeaderView.h"

@interface RootViewController : UIViewController <UITableViewDataSource,UITableViewDelegate,EGORefreshTableHeaderDelegate,UIScrollViewDelegate>{

EGORefreshTableHeaderView *_refreshHeaderView;
BOOL _reloading;
}

RootViewController.m添加相应的元素：
-(void)viewDidLoad {
[super viewDidLoad];
//创建self.tableView的方法和委托暂时去掉，不属于本篇讨论内容

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;
[_refreshHeaderView refreshLastUpdatedDate];
}

#pragma mark -
#pragma mark Data Source Loading / Reloading Methods
-(void)reloadTableViewDataSource{
_reloading =YES;
}

-(void)doneLoadingTableViewData{
_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;
}

-(NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{
return[NSDate date];
}
