I was making a user interface using storyboards and when I built my app to see how it would look in the iOS simulator it didn't look like the viewcontroller in the storyboard (some of the buttons were moved around and I had to move one button way down so it was in the place i wanted it to be). Does anyone know why this is?

Yes, the reason is auto layout, it will automatically position elements on a relative basis depending on the device you're running.

You can turn autolayout off, or build for all devices at once and keep it on.
