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 th开发者_运维知识库is?

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

self.navigationItem.hidesBackButton = YES;

---

Your above line is wrong. do it with :

 self.navigationController.navigationItem.hidesBackButton = TRUE;

---

You can write this in your ViewDidLoad as well as in ViewWillAppear method:

self.navigationItem.hidesBackButton = YES;

The existing answers didn't work for me. I found that the best way for me was:

self.navigationItem.leftBarButtonItems = [NSArray array];
