I have two views: View A and View B
我有两个视图：视图 A 和视图 B
I add a navigation bar to view A, after I used self.navigationController!.pushViewControllerto show view B.
在我用来self.navigationController!.pushViewController显示视图 B之后，我添加了一个导航栏来显示视图 A。

The Swift version of Vahan Babayan's answer, as you seem to use this language, is:
Vahan Babayan 的答案的 Swift 版本，正如您似乎使用这种语言一样，是：
let rightButtonItem = UIBarButtonItem.init(
title: "Title",
style: .Done,
target: self,
action: "rightButtonAction:"
)
self.navigationItem.rightBarButtonItem = rightButtonItem
The following method will be called on self:
将在 self 上调用以下方法：
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.
请注意，所有这些都可以使用 Storyboard以图形方式设置，方法是将 Bar Button Item 拖动到您的 Navigation Item 并右键单击以设置目标操作。
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:
Swift 3 和 4 发布后的一个小更新：编译器现在可以检查选择器名称，防止在以编程方式设置目标操作时出现拼写错误。所以一个人真的应该使用：
let rightButtonItem = UIBarButtonItem.init(
title: "Title",
style: .Done,
target: self,
action: #selector(rightButtonAction(sender:))
)

You can add the following code to your B controller's viewDidLoadmethod.
您可以将以下代码添加到 B 控制器的viewDidLoad方法中。
UIBarButtonItem *rightButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Title"
style:UIBarButtonItemStyleDone
target:self
action:@selector(rightButtonAction:)];
self.navigationItem.rightBarButtonItem = rightButtonItem;

- (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
}

Swift code to add a navigation bar button item:
添加导航栏按钮项的Swift代码：
Method 1(When you wanna use bar button system item)
方法一（当你想使用条形按钮系统项时）
navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
Method 2(When you wanna give your own title to button)
方法 2（当你想给自己的按钮标题时）
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:
从 iOS 5 开始，它允许您在导航栏的任一侧添加 1 个以上的按钮。像这样的东西：
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]

Add below code in viewDidLoad Method
在 viewDidLoad 方法中添加以下代码
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:
这会在右侧添加一个标题为 Flip 的按钮，该按钮调用该方法：
-(IBAction)flipView
