    <p>If you're using Auto Layout, here's what you need to do:</p> <ol> <li><p>Make sure you aren't adding fixed width and/or height constraints to any of your subviews (depending on which dimension(s) you want to dynamically size). The idea is to let the intrinsic content size of each subview determine the subview's height. <code>UILabel</code>s come with 4 automatic implicit constraints which will (with less than Required priority) attempt to keep the label's frame at the exact size required to fit all the text inside.</p></li> <li><p>Make sure that the edges of each label are connected rigidly (with Required priority constraints) to the edges of each other and their superview. You want to make sure that if you imagine one of the labels growing in size, this would force the other labels to make room for it and most importantly force the superview to expand as well.</p></li> <li><p>Only add constraints to the superview to set its position, not size (at least, not for the dimension(s) you want it to size dynamically). Remember that if you set the internal constraints up correctly, its size will be determined by the sizes of all the subviews, since its edges are connected to theirs in some fashion.</p></li> </ol> <p>That's it. You don't need to call <code>sizeToFit</code> or <code>systemLayoutSizeFittingSize:</code> to get this to work, just load your views and set the text and that should be it. The system layout engine will do the calculations for you to solve your constraints. (If anything, you might need to call <code>setNeedsLayout</code> on the superview...but this shouldn't be required.)</p>
