title: Is an iphones screen resolution 320x460, or 320x480?
body: <p>I'm so confused. I don't have a status bar, and I don't know how to make my scroll view's dimensions. Is it 320 x 480, or 320 x 460? Because when I drag it out onto storyboard and it fills the entire screen it says it is 320 x 460, but then when I add subviews to it they get positioned strangely and so that it's like the views are 20 pixels short or something.</p>
  
  <p>EDIT: I'm just a little confused because when my status bar goes away, it doesn't re adjust the view size, it just makes the view 20 pix shorter, which doesn't really make sense, right? Shouldn't it make it 20 pix longer instead of just cutting off 20 pix?</p>
