切换到另一个视图时显示导航栏

Question

I have a button when it pressed, I want it to take me to another view (the "news" view). Within the news view, I want there to be a navigation bar with a back button. I have a navigationcontroller setup throughout my app but I can't seem to get this to work when this button is pressed. It takes me to the view I want but there is no navigation bar and no back button. This is my code that is implemented when the button is pressed.

If anybody know what I am doing wrong, it would be much appreciated.

Thanks

-(IBAction)news
{
newsViewController *view1 = [[newsViewController alloc] initWithNibName:@"newsViewController" bundle:nil];
view1.title=@"news";
[self.navigationController pushViewController:view1 animated:YES];
}

Answer 1

I am not in my mac, so I can not test code, but if it is working and the only issue you got is not show the bar, what you need to is set the bar to be visible:

From apple docs:

The navigation toolbar is hidden by default but you can show it for your navigation interface by calling the setToolbarHidden:animated: method of your navigation controller object. If not all of your view controllers support toolbar items, your delegate object can call this method to toggle the visibility of the toolbar during subsequent push and pop operations.

Something like that is supposed to work:

-(IBAction)news {
    newsViewController *view1 = [[newsViewController alloc] initWithNibName: @"newsViewController" bundle:nil];
    view1.title=@"news";

    [self.navigationController pushViewController:view1 animated:YES];

    //Add this line!
    [self.navigationController setNavigationBarHidden:NO animated:YES];
}

I hope it can help you.

write the below code in page where you want to show navigation controller 
- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    self.navigationController.navigationBarHidden = NO;
}
