UISearchBar  searchbar =[[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];

        searchbar.showsCancelButton=NO;

        searchbar.barStyle=UIBarStyleDefault;

        searchbar.placeholder=@"aaaaaa";

        searchbar.keyboardType=UIKeyboardTypePhonePad;

        

        [cell addSubview:searchbar];

        [searchbar release];

添加搜索框事件：

-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{

    [searchBar setShowsCancelButton:YES animated:YES];

    self.tableView.allowsSelection=NO;

    self.tableView.scrollEnabled=NO;

}

添加Cancel事件：

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{

    searchBar.text=@"";

    [searchBar setShowsCancelButton:NO animated:YES];

    [searchBar resignFirstResponder];

    self.tableView.allowsSelection=YES;

    self.tableView.scrollEnabled=YES;

}

添加搜索事件：

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{

    NSArray *results;

    [searchBar setShowsCancelButton:NO animated:YES];

    [searchBar resignFirstResponder];

    self.tableView.allowsSelection=YES;

    self.tableView.scrollEnabled=YES;

    [self.tableDate removeAllObjects];

    [self.tableDate addObjectsFromArray:results];

    [self.tableView reloadData];

}

最后绑定数据就是

复制数据的

-(void)resetSearch{

    self.names=[self.allNames mutabledeepCopy];

    NSMutableArray *keyArray=[[NSMutableArray alloc]init];

    keyArray addObjectsFromArray:[self.allNames allkeys]sortedAaa>>>>>:[[@selector(compare;) ]];

    self.keys=keyArray;

    [keyArray release];

}

实现搜索的

-(void)handleSearchForTerm:(NSString *)searchterm{

    NSMutableArray *s=[[NSMutableArray alloc]init];

    [self resetSearch];

    for (NSString *key in self.keys){

        NSMutableArray *array=[names valueForKey:key];

        NSMutableArray *toRemove=[[NSMutableArray alloc]init];

        for (NSString *name in array) {

            if([name rangeOfString:searchterm options:NSCaseInsensitiveSearch].location==NSNotFound)

                [toRemove addObject:name];

        }

        if ([array count]==[toRemove count]) {

            [s addObject:key];

            [array removeObjectsInArray:toRemove];

            [toRemove release];

        }

        [self.keys removeObjectsInArray:s];

        [s release];    

    } 

}
