Dynamic UIPopoverController Size?

I have a UIPopoverController in my app which simply displays two UILabels beside each other with a list of words in each of them. However sometimes there are only a couple of words in each list meaning there is tons of blank space in the popover view.

How can I make it so that the popover view in at least height dynamically adapts to how many lines of words there are in my label?

If text in label is specified before popover shows, you can achieve this by using similar code in viewDidLoad method:

- (void)viewDidLoad {
    [super viewDidLoad];

    // ...

    CGFloat height = [label.text sizeWithFont:label.font 
                                     forWidth:label.frame.size.width 
                                lineBreakMode:label.lineBreakMode].height;

    // This calculates only height of the label, you may want to add some margins, etc. 

    CGSize size = CGSizeMake(self.view.frame.size.width, height);
    self.contentSizeForViewInPopover = size;
}
