Answer 1

The presence or absence of a Nib file within the application does not affect its ability to handle touches, either in buttons or through direct touch handling. For example, my iPhone/iPad application Molecules (for which the source code is available under the BSD license) has both buttons for changing state and gestures for interacting with an OpenGL ES model, yet it doesn't use Interface Builder for any part of its interface.

You can get the same interface capabilities whether you implement them in Interface Builder or in code.
