如何在使用UISearchBar時更改UIKeyboard？

Question

我想將UISearchBar的鍵盤類型設置爲UIKeyboardAppearanceAlert，但我似乎無法訪問UISearchBar的UIKeyboard。

Answer 1

您需要訪問UISearchBar本身的內部UITextField。

UITextField *textField = (UITextField *)[[searchBar subviews] objectAtIndex:0]; 
textField.keyboardAppearance = UIKeyboardAppearanceAlert;
