UIModalPresentationPopover for iPhone 6 Plus in landscape doesn't display popover

Question

I want to always present a ViewController in a popover on all devices and all orientations. I tried to accomplish this by adopting the UIPopoverPresentationControllerDelegate and setting the sourceView and sourceRect.

This works very well for all devices and orientations, except the iPhone 6 Plus in landscape. In that case the view controller slides up from the bottom of the screen in a form sheet. How can I prevent that so that it will always appear in a popover?

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let popoverPresentationController = segue.destinationViewController.popoverPresentationController
popoverPresentationController?.delegate = self
popoverPresentationController?.sourceView = self.titleLabel!.superview
popoverPresentationController?.sourceRect = self.titleLabel!.frame }

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.None }

All device are under iOS 8.2 or higher

Answer 1

Implement the new adaptivePresentationStyleForPresentationController:traitCollection: method of UIAdaptivePresentationControllerDelegate:

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller traitCollection:(UITraitCollection *)traitCollection {
    // This method is called in iOS 8.3 or later regardless of trait collection, in which case use the original presentation style (UIModalPresentationNone signals no adaptation)
    return UIModalPresentationNone;
}

UIModalPresentationNone tells the presentation controller to use the original presentation style which in your case will display a popover.
