Navigation bar back button text is not changing

Question

I am trying to change the text of the navigation bar back button text. I have tried the solutions offered here but I cant get the text I want on back button. In appdelegate I set these features:

 [[UINavigationBar appearance] setBarTintColor:[self colorWithHexString:@"e74c3c"]];

 [[UINavigationBar appearance] setBarTintColor:[self colorWithHexString:@"e74c3c"]];   



[[UINavigationBar appearance] setTitleTextAttributes:

 [NSDictionary dictionaryWithObjectsAndKeys:

  [UIColor whiteColor], UITextAttributeTextColor,

  [UIFont fontWithName:@"Futura-CondensedMedium" size:19.0], UITextAttributeFont,nil]];



NSShadow *shadow = [[NSShadow alloc] init];

shadow.shadowOffset = CGSizeMake(0.0, 1.0);

shadow.shadowColor = [UIColor whiteColor];



[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil]

 setTitleTextAttributes:

 @{NSForegroundColorAttributeName:[UIColor whiteColor],

   NSShadowAttributeName:shadow,

   NSFontAttributeName:[UIFont fontWithName:@"Futura-CondensedMedium" size:19.0]

   }

 forState:UIControlStateNormal];



[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

And in every viewcontroller's

viewdidload

I set:

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"SomeText" style:UIBarButtonItemStylePlain target:nil action:nil];

or

UIBarButtonItem *newBackButton = 

        [[UIBarButtonItem alloc] initWithTitle:@"NewTitle" 

                                         style:UIBarButtonItemStyleBordered 

                                        target:nil 

                                        action:nil];

[[self navigationItem] setBackBarButtonItem:newBackButton];

Any suggestions?

If I haven't misunderstood you you can do this to set the title of the back button. Suppose there are three view controllers: A, B and C. Now you want the title of the back button to be "MyViewA" when you navigate from A to B then you need to put this code in "viewWillAppear:" of your ViewController A (this will show the title of the back button as "MyViewA" when you are on view controller B).

 //viewWillAppear of ViewController A
 -(void)viewWillAppear:(BOOL)animated{

       //now set title of back button
       self.navigationItem.backBarButtonItem =
       [[UIBarButtonItem alloc] initWithTitle:@"YourTitle"
                                  style:UIBarButtonItemStyleBordered
                                 target:nil
                                 action:nil];
 }

Likewise if you are navigating from B to C and want to set the back button title for ViewController C, you need to put the above code in "viewWillAppear:" delegate of ViewController B. In short you need to set the title of the next view controller on your current view controller.
