Question

I have a set of table views which the user can switch between using a tab bar controller, each table view has the same background.
Rather than have each table display the same background image I instead can do either of these:

[myDelegate.window addSubview: theUIImageView];

or

[myDelegate.window.rootViewController addSubview:theUIImageView];

Both work, should one be used rather than the other and why?

I have a similar question for displaying an activity indicator.

Thanks

Answer 1

I think the principle is that the window should have one root view controller at the top of the tree, so I would maintain that. Other rulesets are available!
