title: xcode - autolayout - prevent overlap of logo + input with footer button
body: <p>I am having trouble preventing the text inputs from overlapping the footer button.  </p>
  
  <p>The footer has been anchored to the bottom of the screen.  All the elements up top (logo, title label, and 2 input boxes) all have relative constraints.  I try to add a constraint between that last input and the footer button but it pushes the footer off the screen on the smaller iphone.</p>
  
  <p>What do I do??</p>
