使用UISearchController修复了UISearchBar - 不使用UITableView的标题视图
问题描述：
是否可以将UISearchController的UISearchBar放在除UITableView标题视图以外的地方？
Is it possible to put UISearchBar of UISearchController somewhere other than header view of UITableView?
在苹果的UISearchController示例代码，使用以下内容。
[self.searchController.searchBar sizeToFit];
self.tableView.tableHeaderView = self.searchController.searchBar;
是否有可能将searchBar定位在其他地方？
假设我们想要实现一个固定的UISearchBar，就像在联系人应用程序中使用的那样。
我试过这个但是搜索栏根本没有出现。
Is it possible to position searchBar somewhere else? Say we want to implement a fixed UISearchBar like the one used in contacts app. I've tried this but the searchBar doesn't appear at all.
答
你可以放置UISearchBar导航栏中的UISearchController使其保持固定
You can place the UISearchBar of UISearchController in the navigation bar so that it remains fixed
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.searchBar.searchBarStyle = UISearchBarStyleMinimal;
// Include the search bar within the navigation bar.
self.navigationItem.titleView = self.searchController.searchBar;
self.definesPresentationContext = YES;
