我认为你正在寻找 Text，Web，和编辑iOS编程指南
UIKit框架包括对自定义输入视图和输入附件视图的支持。当用户在视图中编辑文本或其他形式的数据时，您的应用程序可以用自己的输入视图替换系统键盘。例如，应用程序可以使用自定义输入视图从符文字母表中输入字符。您还可以将输入附件视图附加到系统键盘或自定义输入视图;此附件视图沿主输入视图的顶部运行，并且可以包含，例如，以某种方式影响文本的控件或显示有关文本的一些信息的标签。

How do I go about creating a custom keyboard/keypad that will show up when some one taps on a UITextField? I would like to display a keypad with a, b, c, 1, 2, 3 and an enter button, nothing else.

I think you're looking for the "Text, Web, and Editing Programming Guide for iOS"
The UIKit framework includes support for custom input views and input accessory views. Your application can substitute its own input view for the system keyboard when users edit text or other forms of data in a view. For example, an application could use a custom input view to enter characters from a runic alphabet. You may also attach an input accessory view to the system keyboard or to a custom input view; this accessory view runs along the top of the main input view and can contain, for example, controls that affect the text in some way or labels that display some information about the text.
To get this feature if your application is using UITextView and UITextField objects for text editing, simply assign custom views to the inputView and inputAccessoryView properties. Those custom views are shown when the text object becomes first responder...
