Google自动填充广告国家/地区过滤器无法在iOS中使用

Question

let autocompleteController = GMSAutocompleteViewController()
autocompleteController.autocompleteFilter?.country = "AU"
autocompleteController.delegate = self
self.presentViewController(autocompleteController, animated: true, completion: nil)

我只需要过滤澳大利亚的数据，所以我想按国家/地区过滤数据。

Answer 1

默认情况下，autocompleteFilter属性为nil，因此该行

autocompleteController.autocompleteFilter?.country = "AU"

什么都不做 这样做是这样的：

let filter = GMSAutocompleteFilter()
filter.country = "AU"
autocompleteController.autocompleteFilter = filter

Answer 2

 GMSAutocompleteViewController *controller = [[GMSAutocompleteViewController alloc]init]; GMSAutocompleteFilter *filter = [[GMSAutocompleteFilter alloc]init]; controller.delegate = self; filter.country = @"IN"; controller.autocompleteFilter = filter;
