数组中字符串的UISearchBar
我正在尝试使用章节标题，标题文字和字幕文字创建字典类型的应用。我设法使用以下代码使一切工作正常。我唯一想知道的是如何过滤UISearchBar以显示数组中String [Coptic]的结果。这甚至可能是我组织一切的方式还是我需要重组？有没有人有任何建议？
我在底部留下了updateSearchResults空白的代码，因为我不知道要编码什么。
class Gamma: UITableViewController, UISearchBarDelegate, UISearchResultsUpdating {
struct words {
var sectionName : String!
var coptic : [String]!
var english : [String]!
}
var array = [words]()
var filtered = [words]()
var filtered2 = UITableViewController()
var indexarray = ["Ga", "Ge", "Gy", "Gn", "Go", "Gr", "Gw"]
let searchController = UISearchController(searchResultsController: nil)
override func viewDidLoad() {
super.viewDidLoad()
let defaultTextAttribs = [NSAttributedStringKey.font.rawValue: UIFont(name:"CS Avva Shenouda", size:17), NSAttributedStringKey.foregroundColor.rawValue:UIColor.black]
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = defaultTextAttribs as Any as! [String : Any]
self.navigationController?.navigationBar.tintColor = UIColor.white
filtered = array
searchController.searchResultsUpdater = self
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
self.navigationItem.titleView = searchController.searchBar
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 400
tableView.sectionHeaderHeight = 40
tableView.sectionIndexBackgroundColor = UIColor.clear
tableView.sectionIndexMinimumDisplayRowCount = 15
array = [words(sectionName: "Ga", coptic: ["Gabriyl", "gaza", "gazovulakion", "gala", "galynyc", "Galile`a", "galileoc", "gamoc", "gar"], english: ["ghabriyēl\n\n(Heb.) - Gabriel", "ghå`zå\n\n(f.) - Treasure, money chest", "ghåzo`filåk`yon\n\n(Gk.) - Treasury", "ghå`lå\n\n(Gk. m.) - Milk", "ghålēnēs\n\n(Gk. f.) - Gentle, calm", "ghålilā`å\n\nGalilee", "ghålilā`os\n\n(adj.) - Galilean", "ghåmos / gåmos\n\n(Gk. m.) - Wedding, marriage", "ghår\n\n(Gk. conj.) - For, because"]),
