That did not work... seemed hopeful though

to clarify, i think all of the listed methods, including yours, 'set' the barItem...but i can't get it to update without popping the parent view

Delegation, at first thought, seemed like overkill, but it worked perfectly. I couldn't get this working, but if you post one that does or just change your answer to 'use a delegate' i will mark this as correct. someone should get something, i figure.

Answer 2

A:

You need to set the title for the navigationItem that belongs to the 'previous' controller. So in a navigationController that would be the one 'to the left'.

You can set this title first and then push the new view onto the stack.

That is what jacob does, sans pushing a new view onto the stack. I suppose I am not being clear. While i am in the child view, i want to update the back button. Is the only way to do this by making a new button and replacing the old back button?

With child view you mean a subview of the view that is currently on top of the navigation stack? If that's the case, I think Jacobs way should work. Strange...

Answer 3

A:

What I ended up doing was implementing a delegate protocol. my child view tells the parent the new name and the parent sets its title. with self.title = @"foo"
