Swift MapKit UISearchController MKLocalSearchRequest-仅搜索电话号码

Question

我不知道是否有人在某个地方回答了这个问题，因为我刚刚过去一个小时都在寻找答案。我有一个应用程序，企业可以在此注册其实体店位置。问题是，没有实体商店的人正在注册。我计划通过让他们只搜索该商店的电话号码以显示其位置详细信息，而不是地址（实体位置除外）来解决此问题。

如何更改UISearchController / SearchBar / MKLocalSearchRequest以仅需要电话号码并从电话号码开始工作？

还可以搜索电话号码并显示正确的信息，但我不知道电话号码自动完成功能是否存在/有效。...输入完整的电话号码后，将显示正确的位置。

因此，需要帮助以正确的方向指出（教程，示例代码，文档等）

这是我当前的搜索控制器：

import UIKit
import MapKit

class LocationSearchTable: UITableViewController {

weak var handleMapSearchDelegate: HandleMapSearch?
var matchingItems: [MKMapItem] = []
var mapView: MKMapView?


func parseAddress(selectedItem:MKMapItem) -> String {

    // put a space between "4" and "Melrose Place"
    let firstSpace = (selectedItem.placemark.subThoroughfare != nil &&
        selectedItem.placemark.thoroughfare != nil) ? " " : ""

    // put a comma between street and city/state
    let comma = (selectedItem.placemark.subThoroughfare != nil || selectedItem.placemark.thoroughfare != nil) &&
        (selectedItem.placemark.subAdministrativeArea != nil || selectedItem.placemark.administrativeArea != nil) ? ", " : ""

    // put a space between "Washington" and "DC"
    let secondSpace = (selectedItem.placemark.subAdministrativeArea != nil &&
        selectedItem.placemark.administrativeArea != nil) ? " " : ""

    let addressLine = String(
        format:"%@%@%@%@%@%@%@",
        // street number
        selectedItem.placemark.subThoroughfare ?? "",
        firstSpace,
        // street name
        selectedItem.placemark.thoroughfare ?? "",
        comma,
        // city
        selectedItem.placemark.locality ?? "",
        secondSpace,
        // state
        selectedItem.placemark.administrativeArea ?? ""
    )

    return addressLine
}

}

extension LocationSearchTable : UISearchResultsUpdating {
func updateSearchResults(for searchController: UISearchController) {
    guard let mapView = mapView,
        let searchBarText = searchController.searchBar.text else { return }

    let request = MKLocalSearchRequest()
    request.naturalLanguageQuery = searchBarText
    request.region = mapView.region
    let search = MKLocalSearch(request: request)

    search.start { response, _ in
        guard let response = response else {
            return
        }
        self.matchingItems = response.mapItems
        self.tableView.reloadData()
    }

}

}

extension LocationSearchTable {

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

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell")!
    let selectedItem = matchingItems[indexPath.row]
    cell.textLabel?.text = selectedItem.name
    cell.detailTextLabel?.text = parseAddress(selectedItem: selectedItem)
    return cell
}

}

extension LocationSearchTable {

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let selectedItem = matchingItems[indexPath.row]
    handleMapSearchDelegate?.dropPinZoomIn(placemark: selectedItem)
    dismiss(animated: true, completion: nil)
}

}
