我正在使用谷歌自动完成搜索地址。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。

SearchResultsController

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()
    }
}

桌面视图

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

非常感谢您的帮助。

使现代化

上面是上的断点。在tableView上重新加载数据()。
因此,将重新加载表,并用结果填充数组。问题是CellForRowatinex没有因为某种原因被调用!?

您不需要添加tableview 请检查下面的代码

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)
    }
}
