我正在尝试使用UISearchControlleriOS 8中的新功能,并将其嵌入UISearchBar到我的UINavigationBar.这很容易完成如下:
searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.delegate = self
searchController.searchBar.delegate = self
searchController.dimsBackgroundDuringPresentation = false
searchController.hidesNavigationBarDuringPresentation = false
navigationItem.titleView = searchController.searchBar
但是当我添加范围按钮时:
searchController.searchBar.showsScopeBar = true
searchController.searchBar.scopeButtonTitles = ["Posts, Users, Subreddits"]
它添加了背后的按钮UISearchBar,显然看起来很奇怪.
我该怎么做？
