数组 – 将项添加到对象中

我希望能够将个人位置附加到MKLocationSearchCompletion数组中,当用户搜索搜索栏时可以找到该数组.但是,我无法理解项目如何存储到对象中以及是否可以将地标对象(或位置信息)添加到MKLocationSearch对象中.我从文档中获得的是MKLocalSearchCompleter对象存储当用户在搜索栏中键入部分字符串时访问的字符串.但我不知道在哪里可以访问此阵列并添加新位置.

以下是代码的结构,以显示搜索完成结果：

var searchCompleter = MKLocalSearchCompleter()
var searchResults = [MKLocalSearchCompletion]()

@IBOutlet weak var searchBar: UISearchBar!

override func viewDidLoad() {
    searchCompleter.delegate = self
    searchBar.delegate = self
}

extension ViewController: MKLocalSearchCompleterDelegate {
    func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) {
        searchResults = completer.results
        searchResultsTableView.reloadData()
    }

    func completer(_ completer: MKLocalSearchCompleter,didFailWithError error: Error) {
        // handle error
    }
}

extension ViewController: UITableViewDataSource {
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
        return searchResults.count
    }

    func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let searchResult = searchResults[indexPath.row]
        let cell = UITableViewCell(style: .subtitle,reuseIdentifier: nil)

        cell.textLabel?.attributedText = highlightedText(searchResult.title,inRanges: searchResult.titleHighlightRanges,size: 17.0)
        cell.detailTextLabel?.attributedText = highlightedText(searchResult.subtitle,inRanges: searchResult.subtitleHighlightRanges,size: 12.0)

        return cell
    }
}

extension ViewController: UISearchBarDelegate {
    func searchBar(_ searchBar: UISearchBar,textDidChange searchText: String) {
        searchCompleter.queryFragment = searchText
    }

    func searchBarShouldEndEditing(_ searchBar: UISearchBar) -> Bool {
        self.searchBar.endEditing(true)
        searchBar.resignFirstResponder()
        return true
    }
}

class CustomSearchResult {
    let title: String
    ...
}

enum SearchResultType {
    case localSearchResult(result: MKLocalSearchCompletion)
    case customresult(result: CustomSearchResult)
}

var searchResults = [SearchResultType]()

searchResults = completer.results.map { 
   SearchResultType.localSearchResult(result: $0) }

// Add here custom results
searchResults.append(SearchResultType.customresult(result: 
    CustomSearchResult(title: "test")))

let searchResult = searchResults[indexPath.row]
switch searchResult {
case .customresult(let result):
    cell.textLabel.text = result.title
case .localSearchResult(let result):
    cell.textLabel.text = result.title
}
