Question

I tried to remove the backbutton of uinavigationcontroller by using

appdelegate.navigationController.navigationItem.hidesBackButton=YES;

but it does not remove the backbutton after the pushing a new viewcontroller into navigation stack.How to hide this?

Answer 1

In the view controller's viewDidLoad method that you want to hide the back button:

self.navigationItem.hidesBackButton = YES;

Answer 2

Your above line is wrong. do it with :

 self.navigationController.navigationItem.hidesBackButton = TRUE;
