Question

我使用SPGooglePlacesAutoComplete github库在iOS 7中为MapKit实施谷歌地方自动完成API。在仔细实施了我希望用户将Annotation移动到所选位置的最后阶段后，它会给出错误Domain=kCLErrorDomain Code=8。
这在用户从自动完成结果中选择特定位置后发生。这就是我在didSelectRowAtIndexPath方法中所做的事情：

[self.searchDisplayController setActive:NO animated:YES];
SPGooglePlacesAutocompletePlace *place = [placesArray objectAtIndex:indexPath.row];

[place resolveToPlacemark:^(CLPlacemark *placemark, NSString *addressString, NSError *error) {
    if (error) {
        SPPresentAlertViewWithErrorAndTitle(error, @"Could not map the selected Place");

    }else if (placemark) {

        [selectedPlaceAnnotation setCoordinate:placemark.location.coordinate];

        locationLat = selectedPlaceAnnotation.coordinate.latitude;
        locationLon = selectedPlaceAnnotation.coordinate.longitude;

        [defaults setFloat:locationLat forKey:@"locLat"];
        [defaults setFloat:locationLon forKey:@"locLon"];


        selectedPlaceAnnotation.title = @"You Selected This Location";

        if (![self.MapView.annotations containsObject:selectedPlaceAnnotation]==YES) {
            [self.MapView addAnnotation:selectedPlaceAnnotation];
        }

        //[self.MapView animateToLocation:placemark.location.coordinate];

        MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(placemark.location.coordinate, 800, 800);
        [self.MapView setRegion:[self.MapView regionThatFits:region] animated:YES];


            [self.searchDisplayController.searchResultsTableView deselectRowAtIndexPath:indexPath animated:NO];
        }
}
     ];

如果我打印resolveToPlacemark个参数，我就会收到Placemark = (null) Address String = (null) Error = Error Domain=kCLErrorDomain Code=8 "(null)"

如果searchQuery.types设置为SPPlaceTypeGeocode，请将SPPlaceTypeEstablishment更改为private void Answer_Checked(object sender, RoutedEventArgs e) // Radio button click { var radio = sender as RadioButton; bool check = Convert.ToBoolean(radio.IsChecked); if(check) { Answer[Convert.ToInt16(radio.GroupName)] = Convert.ToInt16(radio.Tag); } } public async void Check_Result() // Evaluate result { foreach (KeyValuePair<int, int> count in Answer) { if (count.Value == 1) { result++; } } MessageDialog showresult = new MessageDialog(result.ToString()); await showresult.ShowAsync(); Frame.Navigate(typeof(MainPage), null); } public void TestSubmit_Click(object sender, RoutedEventArgs e) // AppBar button click { Check_Result(); }。

来自Place的CLPlacemark无法映射所选的Place
