Question

我设置了Google GMSAutocomplete，如下所示：

private func setupAutocompleteWithTextFieldController() {
    let kTextFieldTop: CGFloat = searchField.frame.origin.y
    let kTextFieldHeight: CGFloat = 44.0
    let kContentRectTop = kTextFieldTop + kTextFieldHeight

    contentRect = CGRectMake(0, kContentRectTop, self.view.bounds.size.width, self.view.bounds.size.height - kTextFieldHeight)

    searchField.autocorrectionType = .No
    searchField.returnKeyType = .Done
    searchField.clearButtonMode = .WhileEditing
    searchField.addTarget(self, action: "searchFieldTextFieldEditingChanged:", forControlEvents: UIControlEvents.EditingChanged)
    searchField.delegate = self

    tableDataSource = GMSAutocompleteTableDataSource()
    tableDataSource.delegate = self

    resultsController = UITableViewController(style: UITableViewStyle.Plain)
    resultsController.tableView.delegate = tableDataSource
    resultsController.tableView.dataSource = tableDataSource
}

并且还实施了代理人UITextFieldDelegate，GMSAutocompleteTableDataSourceDelegate，并且工作得很好。但是，我想将搜索范围限制为locality，administrativeArea和country。例如我不想让它搜索“地方”。让

我知道有过滤器对象;但是，我如何将其应用于我的使用？有什么想法吗？

filter = GMSAutocompleteFilter()，filter.type = GMSPlacesAutocompleteTypeFilter.City

Answer 1

您可以设置GMSAutocompleteTableDataSource的{{3}}字段。

Answer 2

Google auto complete api

func placeAutocomplete() { //Call function from your search editing method
 let filter = GMSAutocompleteFilter()
 filter.type = GMSPlacesAutocompleteTypeFilter.City
  //"YOUR_SEARCH_DATA" Ex. Sydney Oper
 //Uou will get data for  city sydney
 placesClient?.autocompleteQuery("YOUR_SEARCH_DATA", bounds: nil, filter: filter, callback: { (results, error: NSError?) -> Void in
  if let error = error {
    println("Autocomplete error \(error)")
 }
  for result in results! {
  if let result = result as? GMSAutocompletePrediction {
    println("Result \(result.attributedFullText) with placeID \(result.placeID)")
  }
  }
 })
}

Google Places API，GMSAutocomplete仅搜索City，Country iOS Swift
