title: Height and Width of buttons not the same (ios)
body: <p>I have a grid made of iOS buttons (think Sudoku). I assigned each button to have aspect ratio 1:1. To further ensure their equality, I have made each button have width = height constraint set.</p>
  
  <p>However, when I look at the buttons, some of them have 44x45, while others have 44x44 (as expected). </p>
  
  <p>Is there a constraint that I'm missing or is there a workaround that can guarantee my buttons are perfect squares.</p>
