Pop over doesn't point over the button

Question

I have an application that is compatible with both iPhone and iPad layouts. For iPhone layout I have created Action Sheet and Pop over for iPad. The problem is pop over\'s arrow

Answer 1

For me worked using the sender and casting as UIView.

alertController.popoverPresentationController?.sourceView = sender as! UIView
alertController.popoverPresentationController?.sourceRect = sender.bounds

alertController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.Up

Answer 2

Set the sourceView and sourceRect as the button and button.bounds.
You can choose the permittedArrowDirections depending on the layout of your view.

actionSheet.popoverPresentationController?.sourceView = button
actionSheet.popoverPresentationController?.sourceRect = button.bounds;
actionSheet.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.Left;

If the button is a BarButtonItem use this code.

actionSheet.popoverPresentationController?.barButtonItem = button
actionSheet.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.Up;

This worked for me when my button was a UIBarButtonItem:

if UIDevice.current.userInterfaceIdiom == .pad {

    if controller.responds(to: "popoverPresentationController") {
        controller.popoverPresentationController?.barButtonItem = YourUIBarButtonName
    }

}

Entire code snippet below:

func presentActivitySheet() {

    let controller = UIActivityViewController(activityItems: [document.fileURL], applicationActivities: nil)

        if UIDevice.current.userInterfaceIdiom == .pad {

            if controller.responds(to: "popoverPresentationController") {
            controller.popoverPresentationController?.barButtonItem = YourUIBarButtonName
            }

        }

    present(controller, animated: true, completion: nil)
}
