一、找到你的 UITableView / UITableViewController 的 .h 文件，结合以下代码，添加相应的元素：
#import "EGORefreshTableHeaderView.h" @interface RootViewController
: UITableViewController
{ EGORefreshTableHeaderView
*_refreshHeaderView;
// Reloading var should really be your tableviews datasource // Putting it here for demo purposes BOOL _reloading;
} - ( void )reloadTableViewDataSource;
- ( void )doneLoadingTableViewData;
@end 二、切换到你的 UITableView / UITableViewController 的 .m 文件，结合以下代码，添加相应的元素：
- ( void )viewDidLoad
{ [super viewDidLoad
];
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
];
} #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 } - ( * )egoRefreshTableHeaderDataSourceLastUpdated
: (EGORefreshTableHeaderView
* )view
{ return [ date
];
// should return date data source was last changed } 三、最后呢，为了彰显你良好的内存管理习惯，别忘了释放掉相应的 UI 元素：
- ( void )viewDidUnload
{ _refreshHeaderView
= nil;
} - ( void )dealloc
{ _refreshHeaderView
= nil;
[super dealloc
];
} 四、编译之前，别忘了将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。
