Do i have to resize all my images from iPhone to iPad for universal device?

Posted at: 2014-12-18 
I just finished making my 1st iphone game app and now want to make that game for iPad. I thought i can just copy/paste into iPad and the screen will adjust itself according to size. That didn't work. Does this mean i'm going to have to now resize all my images? Or is there a button i can press that resizes all my images from iPhone to iPad in the universal device xcode 5?
