带有 scopeBar 奇怪行为的 searchBar
searchBar with scopeBar weird behaviour
我遇到了 searchBar 和 scopeBar 的问题。 Bascialy 一旦我单击 "cancel" 并设置 searchBar.showsScopeBar = false
,在下次出现 searchBar 时得到这个奇怪的 space。
这里有一些代码:
override func viewDidLoad() {
super.viewDidLoad()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.hidesNavigationBarDuringPresentation = true
controller.searchBar.searchBarStyle = UISearchBarStyle.Minimal
controller.searchBar.delegate = self
controller.searchBar.sizeToFit()
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
以及显示和隐藏范围栏背后的逻辑:
func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
self.resultSearchController.searchBar.showsScopeBar = true
self.resultSearchController.searchBar.scopeButtonTitles = ["All", "Hot", "Active", "Warm"]
self.resultSearchController.searchBar.sizeToFit();
return true
}
func searchBarShouldEndEditing(searchBar: UISearchBar) -> Bool {
self.resultSearchController.searchBar.showsScopeBar = false
return true
}
这就是正在发生的事情:
我可以接受始终可见的 scopeBar 栏,但是当创建过程中在 searchBar 之前弹出时,当我详细介绍时,它会落在下面。所以比现在更惨。
您可以在创建 UISearchController 本身的过程中创建范围栏(它仅在搜索栏处于活动状态时可见)。您无需手动显示或隐藏范围栏。
override func viewDidLoad() {
super.viewDidLoad()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.hidesNavigationBarDuringPresentation = true
controller.searchBar.searchBarStyle = UISearchBarStyle.Minimal
controller.searchBar.delegate = self
controller.searchBar.sizeToFit()
controller.searchBar.scopeButtonTitles = ["All", "Hot", "Active", "Warm"]
definesPresentationContext = true
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
看到这个有点晚了,但以防其他人看到这个。从@Slavomir 代码中删除下面这两行应该会给你你正在寻找的结果,因为不需要设置 showsScopeBar。
self.resultSearchController.searchBar.showsScopeBar = true
//移除
self.resultSearchController.searchBar.showsScopeBar = false
//移除
