I have an App that pushes many UIViewControllers. If one view has data that has been changed I need to prevent the user from pressing the standard back navigation button.
I thought I could just implement the UINavigationBarDelegate Protocol function shouldPopItem:
In Interface builder I added a NavigationBar and set the Delegate to the FileOwner.
However, if I add the function
- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
It never gets called.
Is it not possible to prevent the Navigation controller for poping a view?
Thanks
Shawn
