Answer 1

Try this....

- (void)viewWillAppear:(BOOL)animated
{
   CGSize size = CGSizeMake(320, 845); // size of view in popover
   self.contentSizeForViewInPopover = size;
   [super viewWillAppear:animated];
}

Answer 2

That's not going to work for iOS 7.

popoverController.popoverContentSize = CGSizeMake(320, 845);

is what you're looking for.
