unrecognized selector sent to instance... Using segues to pass a string to another view controller

Question

I am trying to pass a link to a custom controller, (GMWebView, a subclass of UIViewController with a UIWebView in it) and I get this error:

2013-03-05 20:34:37.930 viei_A6[3233:c07] -[UIViewController setLink:]: unrecognized selector sent to instance 0x71b91d0 2013-03-05 20:34:37.931 viei_A6[3233:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController setLink:]: unrecognized selector sent to instance 0x71b91d0'

My program uses a segue to move into GMWebView, and I am setting the link for the UIWebView object.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    if ([[segue identifier] isEqualToString:@"pushGMWeb"]) {
        //NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        //NSDate *object = _objects[indexPath.row];
        //[[segue destinationViewController] setDetailItem:object];
        GMWebView *detailViewController = [segue destinationViewController];
        NSLog(@"HERE is the link: __ %@",[[channel.items objectAtIndex:[self.tableView indexPathForSelectedRow].row] link]);
        //it crashes when the following line is executed
        detailViewController.link = [[channel.items objectAtIndex:[self.tableView indexPathForSelectedRow].row] link];
    }
}

And here is setLink:

- (void)setLink:(NSString *)newLink
{
    NSLog(@"testing for crash");
    if (link != newLink) {
        link = newLink;
        // Update the view.
        [self configureView];
    } 
}

Any help would be nice, it is the only thing holding me back from finishing my app at the moment

Check the class of this view controller on the storyboard. It looks like the actual class is UIViewController. You want to change it to GMWebView
