Question

I have a structure like this….

UITableViewController -> UITableViewCell -> UIView

I need the UIView to access a HashTable (NSMutableDictionary) in the UITableViewController

Is there a way to access the ViewController simply from the ViewCell (using [ViewCell superview] obviously won’t work) ….Do I need to go down through the AppDelegate using [[UIApplication sharedApplication] delegate]?

Thanks!

Answer 1

I usually maintain a weak reference from my UIView to my UIViewController if I need one, usually by creating a method something like this:

-(MyView*)initWithController:(CardCreatorViewController*) aController andFrame:(CGRect)aFrame
{
    if (self = [super initWithFrame:aFrame]) 
    {
       controller = aController;
       // more initialisation here
    }

    return self;
}

You could also use a delegate pattern if you want a more decoupled solution. I tend to think this is overkill for a view and its controller, but I would use it with a system of controllers and subcontrollers.
