Thanks Everyone.
I could not get the
[self.viewController1.label2.text
or the
[self view addSubview:viewController2.view];
to work for some reason. Then it dawned on me that I could set the value right
before I added the Subview!
[viewController2.label2 setText:label1.text];
[self.view addSubview:viewController2.view];
This works, although for some reason the label does not update unless I reload
the view. I will figure out what is going on there.
Thanks for the suggestions.
Steve
