(from Beginning IOS7 Development Exploring the IOS SDK)

UISearchBar *searchBar = [[UISearchBar alloc]
                              initWithFrame:CGRectMake(0, 0, 320, 44)];
tableView.tableHeaderView = searchBar;
searchContoller = [[UISearchDisplayController alloc]
                     initWithSearchBar:searchBar
                     contentsController:self];
searchController.delegate = self;
searchController.searchResultsDataSource = self;

你知道UISearchController中的API是不同的，那怎么办?

推荐答案

来自 苹果文档:

searchController = [[UISearchController alloc] initWithSearchResultsController:nil];

searchController.searchResultsUpdater = self;

searchController.dimsBackgroundDuringPresentation = NO;

searchController.hidesNavigationBarDuringPresentation = NO;

searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y, self.searchController.searchBar.frame.size.width, 44.0);

self.tableView.tableHeaderView = self.searchController.searchBar;

在 UISearchController 上检查这个 SAMPLE PROJECT.
