I have 2 UILabels above 2 UITextFields. I would like the first UITextField to expand when the screen size allows it.
I set vertical spacings between each elements, and fixed height constraint for the UITextField at the bottom and a >= height constraint for the first one.
Below is a screenshot with what it looks like with the retina 3.5 form factor (<= iPhone 4).

But, it just doesn't work. Below is a screenshot of the storyboard with the retina 4 form factor (>= iPhone 5). The first UITextField overlaps the second one.
What constraints should I set ?
