The Popover doesn't resize after a setPreferredContentSize.

[Janne-M]

I make a call to setPreferredContentSize in my viewWillAppear when I have calculated the appropriate size, but the Popover I'm contained in does not respect my change.
This is on iOS8.

I spent some time researching it and to me it look like it's due to the KVO addObserver call on these selectors (setPreferredContentSize & contentSizeForViewInPopover) are made in a concurrent block during initialization.
I have noticed that iOS8 uses a much 'lazier' initialization scheme and that probably pushes these addObserver calls to after my viewControllers viewWillAppear.

I made a small hack and just moved the KVO setup out of the block, back to the main initialization and then it worked as I would expect.
I don't know the reason to put this type of KVO setup in a concurrent block so I'd hope You can come up with a more appropriate and correct solution.

I have the same problem only in iPads with iOS 8. Do you solve it?

I got some issue, to solve I did like this :

popoverController.popoverContentSize = CGSizeMake(width+20, height+20);

in showPop method 🎯

I use autolayout.
when I get UI.frame, I don't change Pop Size
