how to customise color of EKEventEditView displayed by EKEventView?

Question

BACKGROUND:

• I now can see how to customise the color of a EKEventView, which is an apple view that you can use to display a calendar event. The code is per my post here: is this code future proof for customising color of EKEventViews (code attached)

• If this view is EDIT'able however the apple EKEventView class then shows a modal "EKEventEditView" view.

QUESTION:

• My question is how do I customise the color of EKEventEditView, for which the view wasn't trigged by my code, but rather by the apple code in the EKEventView.

LINKS TO API:

• EKEventViewController: http://developer.apple.com/library/ios/#documentation/EventKitUI/Reference/EKEventViewControllerClassRef/Reference/Reference.html

• EKEventEditViewController - http://developer.apple.com/library/ios/#documentation/EventKitUI/Reference/EKEventEditViewControllerClassRef/Reference/Reference.html

I don't know how Apple will respond to this code, but it works :)

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(willShowController:) 
                                             name:@"UINavigationControllerWillShowViewControllerNotification" 
                                           object:nil];

And selector method:

-(void)willShowController:(NSNotification*)sender{
    NSLog(@"%@ ", [sender description]);

    UIViewController *controller = (UIViewController*)[sender object];

    if ([controller isKindOfClass:EKEventEditViewController.class]){
        UITableViewController *rootController = (UITableViewController*)[(UINavigationController*)controller visibleViewController];

        UITableView *tv = (UITableView*)[rootController view];
        [tv setBackgroundColor:[UIColor redColor]];
        UIView *v = (UIView*)[[tv visibleCells] objectAtIndex:0];
        v.backgroundColor = [UIColor blueColor];
    }
}

There is only one string UINavigationControllerWillShowViewControllerNotification which you cannot find in SDK. But in this case it's only the string.. Hope this help you.
