Animate popoverContentsize when pushing navigation view controller in popover on iPad

Question

How do I get my UIPopoverController to animate its size when its contained UINavigationController pushes a new controller?

I think you were close if you tried keeping a reference to the popoverController and used setPopoverContentSize:animated:

What works for me is this combination of setPopoverContentSize:animated: AND contentSizeForViewInPopover in that specific order, for each controller your put on the stack:

-(void)viewDidAppear:(BOOL)animated
{
    [self.popoverController setPopoverContentSize:whateverSize animated:true];
    self.contentSizeForViewInPopover = whateverSize;
    [super viewDidAppear:animated];
}

In this case, self.popoverController is a reference I keep in each controllers that is pushed on the stack, it would probably be cleaner to use a singleton variable for that.
