012 create an ios6.0 application on xcode4.5 (advanced control table view search box)

Advanced Control table view in IOS (add the search box to the table view)
In the previous blog, we implemented the table view control 011 and created the ios6.0 application on xcode4.5.
(Advanced control table view segment table view)
In the previous code, or based on the implementation of the search box, it is actually very simple, as long as you add a control search box there are two types, when selecting the control, we should try to select the following method because the following method has implemented the control and then add the searchbar Protocol to implement the two method protocols:

Uisearchbardelegate

Method:

-(Void) searchbarcancelbuttonclicked :( uisearchbar *) searchbar

-(Void) searchbar :( uisearchbar *) searchbar textdidchange :( nsstring *) searchtext

You can simply implement the effect of a search box. The detailed code viewcontroller. H will be posted below.

@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate,UISearchBarDelegate>{    NSMutableDictionary *allteams;    NSMutableDictionary *teams;    NSArray *teamsname;}@property (nonatomic,retain)NSMutableDictionary *allteams;@property (nonatomic,retain)NSMutableDictionary *teams;@property (nonatomic,retain)NSArray *teamsname;-(void)resetSearch;@end
