    text
    copied!<p>For the last couple of days I am trying to accomplish a fairly simple (at least it should be) layout using auto layout constraints, but without success.</p> <p><em>My view hierarchy is:</em><br> UIScrollView<br> -- UIView (Container view)<br> -----UILabel (Multirow label)<br> -----UIWebView<br> -----UILabel<br> -----UIButton</p> <p><img src="https://i.stack.imgur.com/uuLwF.png" alt="View hierarchy in IB"></p> <p>The desired functionallity is the Container view to be expanding according to the size of the contents. In order to increase the height of the UIWebView I use the following code:</p> <pre><code>- (void)webViewDidFinishLoad:(UIWebView *)webView { [self.webView sizeToFit]; } </code></pre> <p>I tried many different constraints, with the most reasonable ones being:<br> 1. Pin top space from superview for the 1st label (Event Title)<br> 2. Pin vertical spacing for the 1st label and the UIWebView<br> 3. Pin vertical spacing for the rest elements (i.e. UIWebView - UILabel (Event Date) and UILabel (Event Date) - UIButton)<br> 4. The container view has low priority (1) bottom vertical space constraint with its superview</p> <p>The result I get is the following: <img src="https://i.stack.imgur.com/7iR3z.png" alt="enter image description here"></p> <p>The UIWebView expands but does not push down the event date label and the button, plus the Container view does not expand either.</p> <p>Any help would be greatly appreciated.</p> <p>You may download the sample Xcode project <a href="http://nsloom.com/downloads/AutoLayoutDemo.zip" rel="noreferrer">from here.</a></p>
