Get data value from UIPopOverPresentationController to UIViewController?

Question

i want to get the value from the presented popover. I googled around and got this answer

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
    YourViewController *controller =  popoverController.contentViewController;
    MyData *data = controller.yourData;
    //Do something with data
}

But i have used UIPopOverPresentationController. So how am i going to get the value from these delegate method perhapsly

func popoverPresentationControllerDidDismissPopover(popoverPresentationController: UIPopoverPresentationController) {

   // var controller = popoverPresentationController.


}

OR Should i create delegate to pass data back to main View Controller ?

Take a look at the documentation of UIPopoverPresentationController, it inherits from UIPresentationController.

It has the properties presentingViewController and presentedViewController. One of which should reference the controller you want to access and pass data to/get data from:

func popoverPresentationControllerDidDismissPopover(popoverPresentationController: UIPopoverPresentationController) {
    let controller = popoverPresentationController.presentedViewController
    // Fetch data from the presented controller
}
