Dynamic UIPopoverController Size?

Question

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?

Answer 1

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;
}
