How to pull up a UIKeyboard without a UITextField or UITextView?

Question

I'm currently developing an OpenGL ES game for the iPhone and iPod touch.

I was wondering how I can easily pull up the UIKeyboard? Is there an official, documented possibility to pull up a UIKeyboard without using a UITextField of UITextView?

Answer 1

I haven't tried it but http://www.cocoadev.com/index.pl?UIKeyboard shows some code that looks like it should work.

Answer 2

It's not "officially" possible - you can't access the UIKeyboard object at all while staying within Apple's guidelines.

Creating an invisible UITextField, then calling [textField becomeFirstResponder] would do the job - you could even subclass UITextField first, then override the delegate method textField:shouldChangeCharactersInRange: to redirect the text input to where you want it to go.
