Using UINavigationController navigationItem -> rightBarButtonItem
I've seen numerous examples where people stick a UIActivityIndicatorView in the customView of a rightBarButtonItem of UINavigationController. While I like this approach I'm a bit concerned about the potential implications.
Will the UINavigationController never make use of this item for forward navigation for example?
It's OK to use a UIActivityIndicatorView or any other UIView as customView of a rightBarButtonItem; rightBarButtonItem is never used for navigation.
