如何在使用UISearchBar时更改UIKeyboard？

Question

我想将UISearchBar的键盘类型设置为UIKeyboardAppearanceAlert，但我似乎无法访问UISearchBar的UIKeyboard。

Answer 1

您需要访问UISearchBar本身的内部UITextField。

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