Question

我正在创建UISearchViewController，我希望将UISearchBar放在导航控制器的导航项中。这是我如何做到这一点没有结果：

self.searchBar = [UISearchBar new];
self.searchBar.showsScopeBar = YES;
self.searchBar.scopeButtonTitles = @[@"Users", @"Hashtags"];
self.searchBar.delegate = self;

self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchController.delegate = self;
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
self.searchController.displaysSearchBarInNavigationBar = YES;

我也尝试过：

self.searchDisplayController.searchBar.searchBarStyle = UISearchBarStyleMinimal;
self.searchDisplayController.searchBar.scopeButtonTitles = @[@"Users", @"Hashtags"];
self.searchDisplayController.searchBar.showsScopeBar = YES;

我错过了什么或做错了什么？

修改：This和this正是我的目标。

Answer 1

尝试使用以下代码

UISearchBar* searchBar = [[UISearchBar alloc] initWithFrame:CGRectZero];
searchBar.barStyle = UIBarStyleBlack;
searchBar.scopeButtonTitles = [NSArray arrayWithObjects:@"Users", @"Hashtags", nil];
searchBar.showsScopeBar = YES;
self.searchBar.delegate = self;

Answer 2

范围栏仅在搜索栏处于活动状态时显示。搜索显示控制器正在隐藏搜索栏范围栏。

如果您希望示波器栏始终可用，则您必须进行一些小工作。也许其中一个会有所帮助。

编辑：

你有没有尝试过这方面的事情？假设您已将搜索栏添加到导航栏titleView。

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];

    CGRect rect = self.navigationItem.titleView.superview.frame;
    rect.size.height = 88.0f;
    self.navigationItem.titleView.superview.frame = rect;
}

Answer 3

尝试调整searchBar框架： -

UISearchBar* searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake:(0,0,320,88)];
