我正在尝试为iOs8找到displaySearchBarInNavigationBar的替代品,有什么我可以使用的(在
swift中)？
我尝试过self.navigationItem.titleView = resultSearchController.searchBar,但它没有做任何事情.
解决方法
您可以在不使用UINavigationController的情况下将UISearchBar放在UINavigationBar中而不会出现问题,但是您只需要进行一些小改动,首先需要在UINavigationBar中为UINavigationItem定义一个@IBOutlet,但它的名称需要与navigationItem属性不同在所有UIViewController类中定义,请参阅以下代码：
class ViewController: UIViewController,UISearchControllerDelegate,UISearchResultsUpdating,UISearchBarDelegate {
var searchController : UISearchController!
@IBOutlet weak var navigationItemBar: UINavigationItem!
override func viewDidLoad() {
super.viewDidLoad()
self.searchController = UISearchController(searchResultsController: nil)
self.searchController.searchResultsUpdater = self
self.searchController.delegate = self
self.searchController.searchBar.delegate = self
self.searchController.hidesNavigationBarDuringPresentation = false
self.searchController.dimsBackgroundDuringPresentation = true
self.navigationItemBar.titleView = searchController.searchBar
self.definesPresentationContext = true
}
func updateSearchResultsForSearchController(searchController: UISearchController) {
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
然后你可以在你的模拟器中看到这样的东西：
我希望这对你有帮助.
