Is it possible to make a UITextField without rounded edges?

Question

Rounded edges are getting kind of old, and I want my program to have a modern edge. Any idea how this can be done?

To clarify: I want the exact functionality of UITextField without rounded corners.

EDIT: Sorry, I'm a dumbass. I couldn't find the button because the textbox wasn't selected.

Just to help anyone who still runs into this, since it isn't clear enough you can use the Storyboard/Xib Interface Builder:
