UIPopover Not Showing, Causing Crash

Question

I'm using this code to show a popover from the toolbar of the detail view of a split view controller.

- (IBAction)showBookmarksMenu:(id)sender
{
    BookmarksViewController* content = [[BookmarksViewController alloc] init];//UITableViewController
    UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:content];
    aPopover.delegate = self;
    [content release];

    // Store the popover in a custom property for later use.
    self.popoverController = aPopover;
    [aPopover release];

    [self.popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

Getting this crash:

Answer 1

The showBookmarksMenu: method is being called on DetailViewControlleriPad, whereas it should be called on the class which implements it.

Ensure that the method is properly hooked in IB.
