Question

How do you set the popup keyboard to only show certain keys when you type into a textfield? I know there are default keyboards but none seems suitable. Is there an alternative input option? Thanks.

Since iOS 3.2, you can change the keyboard :

The value of this property is nil.
Responder objects that require a
custom view to gather input from the
user should redeclare this property as
readwrite and use it to manage their
custom input view. When the receiver
subsequently becomes the first
responder, the responder
infrastructure presents the specified
input view automatically. Similarly,
when the view resigns its first
responder status, the responder
infrastructure automatically dismisses
the specified view.

This property is typically used to
replace the system-supplied keyboard
that is presented for UITextField and
UITextView objects.
