In ios 6, how do you use pass data between View controller holding 'Container View' object and Table View controller that is embedded in it?

Question

I have a view controller with a label and textfield. I also added a container view which points to another table view controller with one section and 3 rows, basically static table view. I am unable to find any documentation / example which tells you how you pass data between View controller holding the Container View and Table View container embedded in the container view. I want both sided communication ?

Answer 1

The controller embedded in the container view (in storyboard), is automatically added as a childViewController of the controller in which the container view is added. Just to make sense of what I mean, add this line, in your viewDidLoad method of the base controller :

NSLog(@"children : %@", self.childViewControllers);

So lets say in VC1, you add a container view with an embedded controller VC2 (your tableViewController), then the above statement will log VC2 as a child of VC1. To access VC2 from VC1, you just use [self.childViewControllers objectAtIndex:0], and to access VC1 from VC2, just use self.parentViewController.

Hope this helps

If you set things up in a storyboard, you use segues. Just like most everything else in storyboards.
