How to add right button in the navigation bar?

Question

I have a question to add a right button in navigation bar..

I have two views: View A and View B

I add a navigation bar to view A, after I used self.navigat

Answer 1

Add below code in viewDidLoad Method

UIBarButtonItem *flipButton = [[UIBarButtonItem alloc] 
                               initWithTitle:@"Flip"                                            
                               style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(flipView:)];
self.navigationItem.rightBarButtonItem = flipButton;

This adds a button to the right hand side with the title Flip, which calls the method:

-(IBAction)flipView
