Question

I have the schema like that:

----- main view    
       |
        ---right bar view
             |
              ----- Navigation Controller view
                     |
                     ------tableView Controller

how can i remove the right bar view from the window when i’m on tableViewController?

Answer 1

Try this:

 [self.view.superview.superview removeFromSuperview];

Another approach, much cleaner, would be using notifications: you could send a notification to the object controlling your main view, so that it removes it right bar subview. It would be something like:

In your main view controller:

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


- (void) receiveTestNotification:(NSNotification *) notification
{
     <REMOVE SUBVIEW FROM mainView>
}

and in your table view controller:

[[NSNotificationCenter defaultCenter] 
    postNotificationName:@"RemoveRightBarNotification" 
    object:self];

In this case notification will provide a very loose connection between the main view and the table view controller.
