First, click on this link to download the resource file, will EGORefreshTableHeaderView.h, egorefreshtableheaderview.m two files, and Enormego provided by the package of pictures dragged into your project.

Second, find your uitableviewcontroller. h file, add the appropriate code:

#import "EGORefreshTableHeaderView.h" @interface rootviewcontroller:uitableviewcontroller  {  
  
Egorefreshtableheaderview *_refreshheaderview; Reloading Var should really be your tableviews datasource  //Putting it-for demo purposes  BOOL _reloading;  
}-(void) Reloadtableviewdatasource; -(void) doneloadingtableviewdata; @end

Three, switch to your  uitableviewcontroller. m file, add the appropriate code: <pre class= "Prettyprint <a href=" http:= "data-ke-src=" www . ahlinux.com= "" php= "" "=" "target=" _blank "style=" word-wrap:break-word; font-size:16px; margin-top:0px; margin-bottom:0px; padding:0px; line-height:30px; Background-color:rgb (255, 255, 255); >php "> 1-(void) Viewdidload {2 [Super Viewdidload]; 3 4 if (_refreshheaderview = = nil) {5 6 Egorefreshtablehead Erview *view = [[Egorefreshtableheaderview alloc] Initwithframe:cgrectmake (0.0f, 0.0f- Self.tableView.bounds.size.height, Self.view.frame.size.width, Self.tableView.bounds.size.height)]; 7 view. delegate = self; 8 [Self.tableview Addsubview:view]; 9 _refreshheaderview = view; [View release]; One//update the last update date [_refreshheaderview refreshlastupdateddate];

}

 1 #pragma mark-2 #pragma mark Data Source loading/reloading Methods 3 4-(void) reloadtableviewdatasource{5 6  Should be calling your Tableviews the data source model to reload 7//Put here just for demo 8 _reloading = YES; 9 (void) doneloadingtableviewdata{//model should call this is done loading _reloading = NO; [_refreshheaderview EgoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView]; #pragma mark-21 #pragma mark Uiscrollviewdelegate Methods-(void) Scrollviewdidscroll: (Uiscrollvie W *) scrollview{[_refreshheaderview Egorefreshscrollviewdidscroll:scrollview] (MB)-(void) Scrollviewdiden Ddragging: (Uiscrollview *) ScrollView willdecelerate: (BOOL) decelerate{[_refreshheaderview Egorefreshscrollviewdidenddragging:scrollview]; #pragma mark-36 #pragma mark Egorefreshtableheaderdelegate Methods-(void) Egorefreshtableheaderdi Dtriggerrefresh: (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: (E gorefreshtableheaderview*) view{[NSDate Date];//should return date data source is last changed 54 55}

Finally, don't forget the memory management habits, if it is arc management can not dealloc. If it is MRC, then write down all of the following memory releases:

1-(void) Viewdidunload {2 _refreshheaderview=nil 3} 4 5-(void) Dealloc {6 7 _refreshheaderview = nil; 8 [Super Deall OC]; 9}
