Question

I have a viewcontroller that can show several popovers. Not at the same time. Which would be the best way to know which popover is being dismissed at popoverControllerDidDismissPopover?

I have to do different actions regarding the popover that is being dismissed.

Thanks a lot

Something like this should work. (This code is not complete – I assume you know basic memory and class management and other stuff so I focus on the actual problem)

In your class keep some ivars to store reference to the popovercontrollers you created

@interface MyClass : NSObject <UIPopoverControllerDelegate> {
    UIPopoverController *popover1;
    UIPopoverComtroller *popover2;
}

Init your popovercontrollers as usual and save a referance to each of them in popover1 and popover2.

Then in your implementation of the UIPopoverDelegate protocol:

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
    if(popoverController == popover1) {
        //popover1 was dismissed
    } else if (popoverController == popover2) {
        //popover2 was dismissed
    }
}

EDIT: Looking at your comments, it seems that you mean that you are using only ONE popovercontroller, and replacing it’s content view with different UIViewControllers.

If this is the case, I suggest you perform whatever the actions are inside those particular UIViewController in such a way that it affects your application´s state.

Then, once the popover is dismissed, you reload your original view with the new refreshed state.

Or you change it to use two different instances of UIPopoverController instead.
