search - updateSearchResults()没有被调用

我已经阅读过类似的问题和解决方案。但是似乎没有人能解决我的问题。我正在使用自定义搜索 Controller 和自定义搜索栏，并且未调用 func updateSearchResults(用于searchController:UISearchController)。

    var customSearchController: CustomSearchViewController!

CustomSearchViewController:在ViewDidLoad()中

customSearchController = CustomSearchViewController(searchResultsController: ***nil***, searchBarFrame: CGRect(x: 0.0, y: 0.0, width: searchTableView.frame.size.width, height: 44.0), searchBarFont: UIFont(name: "HelveticaNeue", size: 16.0)!, searchBarTextColor: UIColor.purple, searchBarTintColor: UIColor.white)

customSearchController.searchResultsUpdater  = self
customSearchController.definesPresentationContext = true
customSearchController.customSearchBar.placeholder = "What are you looking for?"
customSearchController.customSearchBar.backgroundColor = UIColor.white
customSearchController.customSearchBar.sizeToFit()
customSearchController.customSearchBar.resignFirstResponder()
customSearchController.customSearchBar.showsCancelButton = true
customSearchController.customSearchBar.delegate = self

没有被调用::(

func updateSearchResults(for searchController: UISearchController) {
    filtered.removeAll()
    filtered = searchArray.filter({ (text) -> Bool in
        let tmp: NSString = text as NSString
        let range = tmp.range(of: customSearchController.customSearchBar.text!, options: NSString.CompareOptions.caseInsensitive)
        return range.location != NSNotFound
    })
    self.searchTableView.reloadData()
}

最佳答案

经过几个小时的努力，我能够通过使用以下方法解决该问题:
func searchBar(_ searchBar:UISearchBar，textDidChange searchText:String)-UISearchBarDelegate委托(delegate)方法。

而不是updateSearchResults()-UISearchResultsUpdating委托(delegate)方法

希望它可以帮助某人:)
