iOS Present Popover from bar button item bottom

Question

I have an UIPopoverController that presents an UIViewController using this method:

[self.popover presentPopoverFromBarButtonItem:self.infoBarButtonItem 
                     permittedArrowDirections:UIPopoverArrowDirectionUp
                                     animated:YES];

self.popover is my UIPopoverController.

The code works well, but the Popover arrow is in the middle of the BarButtonItem how do I display the Popover with its arrow "under" the button?

This is what it currently looks like:

Answer 1

In iOS 9 you can try this code:

let alert = UIAlertController(title: "title", message: "message", preferredStyle: UIAlertControllerStyle.ActionSheet)
alert.modalPresentationStyle = UIModalPresentationStyle.Popover
alert.popoverPresentationController?.barButtonItem = sender
presentViewController(alert, animated: true, completion: nil)

Answer 2

How about this

UIBarButtonItem *item = self.infoBarButtonItem ;

UIView *view = [item valueForKey:@"view"];

if(view){

        CGRect frame=view.frame;

        [self.popover presentPopoverFromRect:frame
                                      inView:view.superview
                    permittedArrowDirections:UIPopoverArrowDirectionUp
                                    animated:YES];



}

For all who are using UIViewController with PopoverPresentationController (iOS 9+); This worked for me: you can directly set your UIBarButtonItem like this.

myPopoverPresentationController?.barButtonItem = myUIBarButtonItem
