Answer 1

The Swift version of Vahan Babayan's answer, as you seem to use this language, is:
let rightButtonItem = UIBarButtonItem.init(
title: "Title",
style: .Done,
target: self,
action: "rightButtonAction:"
)
self.navigationItem.rightBarButtonItem = rightButtonItem
The following method will be called on self:
func rightButtonAction(sender: UIBarButtonItem)
Note that all this can be set graphically using a Storyboard, by dragging a Bar Button Item to your Navigation Item and right-clicking to set a target-action.
A small update since Swift 3 and 4 are out: the compiler can now check selector names, preventing typos when setting up target-action programatically. So one should really use:
let rightButtonItem = UIBarButtonItem.init(
title: "Title",
style: .Done,
target: self,
action: #selector(rightButtonAction(sender:))
)

Answer 2

You can add the following code to your B controller's viewDidLoad method.
UIBarButtonItem *rightButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Title"
style:UIBarButtonItemStyleDone
target:self
action:#selector(rightButtonAction:)];
self.navigationItem.rightBarButtonItem = rightButtonItem;

Answer 3

- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *rightBtn = [[UIBarButtonItem alloc]initWithTitle:#"Right Button" style:UIBarButtonItemStyleDone target:self action:#selector(rightBtnClick)];
self.navigationItem.rightBarButtonItem = rightBtn;
}
-(void)rightBtnClick{
// code for right Button
}

Answer 4

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

Answer 5

Swift code to add a navigation bar button item:
Method 1 (When you wanna use bar button system item)
navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
Method 2 (When you wanna give your own title to button)
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Add", style: .plain, target: self, action: #selector(addTapped))
From iOS 5 onwards, it allows you to add more than 1 button on either side of a navigation bar. Something like this:
let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
let display = UIBarButtonItem(title: "Display", style: .plain, target: self, action: #selector(playTapped))
navigationItem.rightBarButtonItems = [add, display]

Answer 6

Try this code for Swift UI :
.navigationBarItems(
leading:
HStack {
Button("About") {
print("About tapped!")
}
Button("Call") {
print("Call tapped!")
}
},
trailing:
HStack {
Button("Settings") {
print("Settings tapped!")
}
Button("Contacts") {
print("Contacts tapped!")
}
}
)
