Is it possible to present a popover without any sort of arrows pointing somewhere?
In my case for swift developers
popoverController.sourceView = self.view
popoverController.sourceRect = self.view.bounds
popoverController.backgroundColor = UIColor.brownColor()
popoverController.permittedArrowDirections = UIPopoverArrowDirection.init(rawValue: 0)
popoverController.sourceRect = CGRectMake(width/4, hieght/4, width/2, hieght/2);
