Pop all views of the stack

Hi all,

I am trying to figure out how to pop all views except for the rootview off the stack so my app. I don't know how many views there will be as it could either be none, one or two that need to be removed. Is there an easy meathid to do this?

I already know how to pop one view.

 

Thanks, feel doppy now, lack of sleep is a terrible thing :S
