Setting property value of parent class viewcontroller from child viewcontroller?

Question

Does anyone know how to update a property value from a subview (child) view controller? I have an int property called statusid defined using gettor / settor in the parent view controller. [self.view addSubview: detailsVC.view];

In the child sub, I try to call [super status: updateValue]; to update statusid to a new value, but this creates an error. How can I update statusid in parent? Does anyone know how to do this?
