swift - 谷歌自动完成不填充表格视图

Question

我正在使用 Google AutoComplete 来搜索地址。我在控制台中得到了一个结果，但是，这并没有填充到 TableView 中。

• 重新加载表格时，我在主队列中。
• 我得到了结果中对象数量的打印计数。

搜索结果控制器

extension ResultsController: UISearchResultsUpdating, UISearchControllerDelegate {

    func updateSearchResults(for searchController: UISearchController) {
        searchController.hidesNavigationBarDuringPresentation = false
        searchController.searchBar.autocorrectionType = .yes
        if searchController.isActive {
            searchController.searchResultsController?.view.isHidden = false
        }
        if searchController.searchBar.text == "" {
            self.searchResults.removeAll()
        } else {
            guard let query = searchController.searchBar.text else { return }
            GMSPlacesClient.shared().autocompleteQuery(query, bounds: nil, filter: self.filteredResults) { (results, error) in
                if error != nil {
                    print(error as Any)
                    return
                } else {
                    guard let results = results else { return }
                    self.searchResults.append(contentsOf: results)
                    print(self.searchResults)
                }
            }
            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        }
    }

    func didDismissSearchController(_ searchController: UISearchController) {
        searchResults.removeAll()
    }
}

表视图

extension ResultsController: UITableViewDelegate, 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 resultsCell = tableView.dequeueReusableCell(withIdentifier: resultsCellIdentifier, for: indexPath)
        let resultsAttributedFullText = searchResults[indexPath.row].attributedFullText.string
        resultsCell.textLabel?.text = resultsAttributedFullText
        return resultsCell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        view.endEditing(true)
    }

控制台输出

[GMSAutocompletePrediction 0x60000053d6e0: "Whittier Boulevard, Whittier, CA, USA", id: EiVXaGl0dGllciBCb3VsZXZhcmQsIFdoaXR0aWVyLCBDQSwgVVNBIi4qLAoUChIJ988tx8bTwoARp1jTzq6WINISFAoSCfeHelWG08KAEVokQMFHfagn, types: (

非常感谢任何帮助。

更新

上面是 tableView 上 .reloadData() 的断点。
因此，正在重新加载表，并用结果填充数组。问题是 cellForRowAtIndex 由于某种原因没有被调用！？

您不需要添加您的表格视图请检查以下代码

import GooglePlaces
import GoogleMaps

class DirectionsViewController: UIViewController, GMSAutocompleteViewControllerDelegate {

    let filter = GMSAutocompleteFilter()

    override func viewDidLoad() {
        super.viewDidLoad()
        txfFromLocation.addTarget(self, action: #selector(autocompleteClicked), for: .editingDidBegin)
    }

    @objc func autocompleteClicked (sender:UITextField!){
        let autocompleteController = GMSAutocompleteViewController()
        autocompleteController.delegate = self
        present(autocompleteController, animated: true, completion: nil)
    }

    //MARK:- GMSAUTOCOMPLETEDELEGATES
    // Handle the user's selection.
    func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        print("Place name: \(place.name)")
        dismiss(animated: true, completion: nil)
    }
}
