ios - 我可以在 iPad 上使用哪种 UIKeyboardType

Question

我的 iPad 应用程序中有一个 textField 对象。我想给用户一个方便的键盘来输入数字。在我的代码中，我添加了:

UITextField *textField = [[UITextField alloc] initWithFrame:frame];
textField.keyboardType = UIKeyboardTypeDecimalPad;

根据文档，这是一种有效的键盘类型，但当我编辑文本字段时，会出现普通的 ASCII 键盘。但是，当我将其更改为:

textField.keyboardType = UIKeyboardTypePhonePad;

键盘看起来像这样:

理想情况下，我想要一个只有数字和小数点的键盘，但这在 iPad 上是不可能的吗？有没有人有关于哪些键盘适用于 iPhone 和 iPad 的明确列表？苹果在这一点上并不清楚。我也看到了这个question这是相似的，但没有一个答案真正解决了我的观点。
