Actually the reason your code is not working is you set the property to your nav bar and then your viewDidLoad get called. In viewDidLoad it loads the nib file and return new allocated navBar. So to Solve this take a global string set it from first view and then in second in viewDidLoad set your navbar's title. Follow Adithya's answer for that.

In second screen declare a property

@property (strong, nonatomic) NSString *newTitle;

and in viewDidLoad

     self.title  = _newTitle;

and in your first screen

  ...
  second.newTitle = @"NEW_TITLE";

I guessing you are trying to set title for your second screen navigation bar.

Use a navigation controller to present your second screen.

In SecondDetailViewController instance, maintain a NSString property.

@property (strong, nonatomic) NSString *navBarTitle;

In viewDidLoad, just set the title.

[self setTitle:navBarTitle];
