tableView加searchBar，以搜索通讯录为列

标签：uisearchdisplaycontr   搜索通讯录   tableview加searchbar   

使用的是storyBoard

1拖一个UISearchDisplayController到tableView的headerView上，并声明成全局变量

@property (strong, nonatomic) IBOutlet UISearchDisplayController *searchDispalyController;

@property (weak, nonatomic) IBOutlet UISearchBar *searchBar;

@property (nonatomic, strong) NSArray * resultModelArr;

2实现代理方法

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope {

    NSPredicate* cate=[NSPredicate predicateWithFormat:@"(SELF.name contains [c] %@) OR ( SELF.phone contains [c] %@)",

                       self.searchBar.text,

                       self.searchBar.text

                       ];

    self.resultModelArr=[self.modelArray filteredArrayUsingPredicate:cate];   

//modelArray 封装的person对象，有name和phone两种属性

}

#pragma mark - UISearchDisplayController delegate methods

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller  shouldReloadTableForSearchString:(NSString *)searchString {

    [self filterContentForSearchText:searchString  scope:[[self.searchDisplayController.searchBar scopeButtonTitles]  objectAtIndex:[self.searchDisplayController.searchBar                                                      selectedScopeButtonIndex]]];

    return YES;

}

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller  shouldReloadTableForSearchScope:(NSInteger)searchOption {

    [self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]];

    return YES;

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    if (tableView == self.searchDispalyController.searchResultsTableView) {

        return _resultModelArr.count;

    }else{

        return _modelArray.count;

    }

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

    PhoneContactCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"PhoneContactCell" forIndexPath:indexPath];//要用self.tableView  否则会崩溃

    PhoneContactModel * model;

    if (tableView == self.searchDispalyController.searchResultsTableView) {

        model= _resultModelArr[indexPath.row];

    }else{

        model= _modelArray[indexPath.row];

    }

    [cell setModel:model];

    return cell;

}
