Make UILabel height zero if label empty/storyboard
<p>I have a lot of labels stacked up for a contact info screen.  If any of the labels are empty, I would love to zero out their height and have them occupy no space to avoid empty space on the screen. However, I have created the screen in storyboard and the labels have been assigned heights and y values.  </p>

<p>Here is code I've been trying to use to alter label height but cannot get it to work.  Perhaps it is designed to work only for labels created programmatically and the storyboard settings override what I am doing here.</p>

<pre><code>NSString *string = @"some text"; 
CGSize maximumLabelSize = CGSizeMake(280,1000);
 
// use font information from the UILabel to calculate the size
CGSize expectedLabelSize = [string sizeWithFont:myLabel.font constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];
 
// create a frame that is filled with the UILabel frame data
CGRect newFrame = myLabel.frame;

// resizing the frame to calculated size
newFrame.size.height = expectedLabelSize.height;

// put calculated frame into UILabel frame
myLabel.frame = newFrame;
</code></pre>

<p>Is there a way to get the height of labels created in storyboard to zero out if they are empty?</p>
