我无法在 iOS 9 的导航栏上添加 UISearch Controller 。互联网上有很多，但没有一个有效。
代码是..
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
searchController.searchResultsUpdater = self;
searchController.delegate = self;
searchController.searchBar.delegate = self;
searchController.hidesNavigationBarDuringPresentation = NO;
searchController.dimsBackgroundDuringPresentation = YES;
self.navigationItem.titleView = searchController.searchBar;
self.definesPresentationContext = YES;
}
-(void)updateSearchResultsForSearchController:(UISearchController *)searchController{}
最佳答案
你应该使用。在上面的代码中，您的设置为 nil。所以它不能初始化。
[searchController = [UISearchController alloc] initWithSearchResultController:self]
这里是 iOS 8/9 的代码:
UISearchController *searchController = [[UISearchController alloc] initWithSearchResultsController:self];
// Use the current view controller to update the search results.
searchController.searchResultsUpdater = self;
// Install the search bar as the table header.
self.navigationItem.titleView = searchController.searchBar;
// It is usually good to set the presentation context.
self.definesPresentationContext = YES;
希望它能帮助您解决问题。保持你的热情!祝你好运。
