How to make UIPopoverController keep same position after rotating?

Question

I can\'t keep popover the same position on the screen after rotation. Is there any good way to do that, because just setting some frame to popover works terrible after rotating.

Answer 1

Swift 3:

    class MyClass: UIViewController, UIPopoverPresentationControllerDelegate {


        ...

        var popover:UIPopoverPresentationController?

        ...

        // Where you want to set the popover...
        popover = YourViewController?.popoverPresentationController
        popover?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
        popover?.delegate = self

        ...

        // override didRotate...
        override func didRotate(from fromInterfaceOrientation: UIInterfaceOrientation) {
          popover?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
        }

}
