Question

Hey,
I’m adding a UIViewcontroller as a subview of my current view. With something like that:

[self.view addSubview:viewcontroller.view];

The user can interact with that added viewcontroller so I can’t just release it after I added it’s view as my subview, right ?

So I would like to release it the dealloc methode and set it to nil in viewDidUnload when my master viewcontroller gets unloaded, right ?

The problem is, the viewcontoller I add as a subview is not added every time. So the question is, how can I ceck if the viewcontroller was added as subview and if so, release it.

Thx a lot !
Sebastian

You can check it like this:

if(viewController)     
{
 [viewController release];
 viewController=nil;
}

and yes u need to put this in your dealloc method.
