Google自動填充廣告國家/地區過濾器無法在iOS中使用

Question

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

我只需要過濾澳大利亞的數據，所以我想按國家/地區過濾數據。

Answer 1

默認情況下，autocompleteFilter屬性為nil，因此該行

autocompleteController.autocompleteFilter?.country = "AU"

什么都不做 這樣做是這樣的：

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;
