iPhone : Hiding / showing Toolbar

Question

I have a toolbar on top of my view with a back button. I would like when the view loads to appear with the toolbar hidden and then, with a touch of the button to appear animated.

--Edit-- I am not using a Navigation Controller.

Answer 1

Before the view is shown:

[self.navigationController setToolbarHidden:YES];

When you press the button:

[self.navigationController setToolbarHidden:NO];
