ios – 我可以在iPad上使用哪种UIKeyboardType

概述我的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,这是一个有效的键盘类型,但是当我编辑文本 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,这是一个有效的键盘类型,但是当我编辑文本字段时,会出现正常的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？有没有人有一个明确的列表,其中哪些键盘适用于iPhone和iPad？苹果目前还不清楚这一点.我也看到了这个类似的question,但没有一个答案能真正解决我的观点.
