Ui exit button trouble

[jbap]

I'm having a bit of ui trouble. I want to remove the X button from the top left corner of the ui screen. I know about the hide_title_bar argument in view.present, but I have buttons in the title bar, and I don't want to remove them. Is there just a way to get rid of the x?

P.S. This is going to XCode, so if I can edit a piece of the template to erase the X, that would be just as great.

Thanks ahead of time!
