Center a UIVIEW on all device sizes

Question

I am workin on an iPhone app and am relatively new to xcode. I am trying to design my application so that no matter what device is used, the main ui will be center. I have a uiview that contains all of my controls (textfields, submit button). I have this uiview centered in interface builder based on the iPhone 5 simulated metrics. When I test this on an iPhone 4 or below, naturally this uiview is not centered but towards the bottom of the screen. Is there a simple way witin interface builder to have this uiview autocenter based on the device? Do I need to add this in programmatically?

Thanks to anyone who can help!

You can use the auto resizing option in the interface builder. Fix the top margin and bottom margin and set flexible height
