UISearchController用法

UISearchController用法

UISearchController和UISearchBar的区别,一个是全屏搜索,一个是搜索框搜索。

在含有UITableView的controller中使用UISearchController


   -   .h文件声明:
        @property (strong, nonatomic) IBOutlet UITableView *tableView;
        @property (nonatomic, strong) UISearchController *searchController;
        使用委托UISearchResultsUpdating
        页面中添加UITableView


   -   .m文件

        - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view.
        self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
        self.searchController.searchResultsUpdater = self;
        [self.searchController.searchBar sizeToFit];
        self.tableView.tableHeaderView = self.searchController.searchBar;
        self.definesPresentationContext = YES;
        
        }

        实现UISearchResultsUpdating 委托方法
        #pragma mark - UISearchResultsUpdating
        - (void)updateSearchResultsForSearchController:(UISearchController *)searchController {
            NSLog(@"Entering:%@",searchController.searchBar.text);
        }
