我讀過類似的問題和解決方案。但似乎沒有解決我的問題。我正在使用自定義搜索控制器和自定義搜索欄和func updateSearchResults（對於searchController：UISearchController）沒有被調用。updateSearchResults（）沒有被調用
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
沒有得到所謂：:(
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()
}
