Q:

Setting content size for a modal popover storyboard segue on iPad?

I have some modal segues in the iPad version of my app, and I'm wondering where / how I tell them what size to display the content? If I was pushing the view controller programmatically I could do this with setContentSize or similar – how/where do I do this when segues are being used?
I'm trying the following but the transitioned view appears full-screen, not in the size I specify – why is that?
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
#pragma unused (sender)
    if ([segue.destinationViewController isKindOfClass:[SignUpViewController class]]) {
        SignUpViewController *signUp = (SignUpViewController *) segue.destinationViewController;
        signUp.contentSizeForViewInPopover = CGSizeMake(100, 100);
    }
}

A:

How about setting popover size directly instead of a view controller size? 
UIStoryboardPopoverSegue *popoverSegue = (id)segue;
popoverSegue.popoverController.popoverContentSize = CGSizeMake(100, 100);

I believe, at this point the popover is already created and resized to a previous value of contentSizeForViewInPopover.
