It works without story boards.

blocks|key|612855|text|在界面生成器或故事板中有一种简单的方法可以做到这一点。在父View+Controller中，只需将导航项目的属性"Back+Button“设置为您想要的任何标题。下面是一个示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|612856|​|612857|📷|atomic|offset|length|612858|612859|Villian的酒馆视图将有"+Back“作为Back+Button标题，就像我们刚刚在父级导航控制器(Best+Bar)的属性检查器中设置的一样。|612860|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/dc1ef123e4b28709130e049fe81e1eda.png|imageAlt^0|0|0|0|1|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@$G|X|H|Y|1|Z]]|A|$]]|$1|I|3|C|5|6|7|10|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|11|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S|T|-4]]]]

There is an easy way of doing that in Interface Builder or Storyboarding. In the parent View Controller, just set the attribute "Back Button" of the navigation item to whatever title you want. Here is an example:

<img src="https://i.stack.imgur.com/KWJoL.png" alt="Set Back Button Title of child view controller form parent view controller">

Villian's Tavern View will have "Back" as Back Button Title, like we just set in the attributes inspector of the parent's navigation controller (Best Bars).

Note:The back button belongs to the previous view controller, not the one currently presented on screen.
To modify the back button you should update it before pushing, on the view controller that initiated the segue:

You can achieve this by using <code>titleView</code> of <code>navigationItem</code>

Swift 3 Answer

• Create one extension for <code>UINavigationItem</code> as Below

<pre><code>extension UINavigationItem {
 func customTitle(title: String) {
 let titleLabel = UILabel()
 titleLabel.text = title
 titleLabel.textColor = UIColor.white
 titleLabel.textAlignment = .center
 titleLabel.sizeToFit()
 titleView = titleLabel
 }
}
</code></pre>

• In your controllers <code>viewDidLoad</code> do the following

<pre><code>override func viewDidLoad() {
 super.viewDidLoad()
 // Do any additional setup after loading the view.
 title = "Text For Back Button"
 navigationItem.customTitle(title: "Title for your view controller")
}
</code></pre>

blocks|key|397062|text|尝试下面的代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|397063|[self.navigationItem+setValue:@[@"customTitle",@""]+forKey:@"abbreviatedBackButtonTitles"];|code-block|syntax|javascript|397064|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Try Below Code :

<pre><code>[self.navigationItem setValue:@[@"customTitle",@""] forKey:@"abbreviatedBackButtonTitles"];
</code></pre>

blocks|key|613165|text|在Xcode12中，UINavigationItem具有backButtonTitle属性|type|unstyled|depth|inlineStyleRanges|entityRanges|data|613166|var+backButtonTitle:+String?+{+get+set+}|code-block|syntax|javascript|613167|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In Xcode 12 UINavigationItem has the backButtonTitle property
<pre><code>var backButtonTitle: String? { get set }
</code></pre>

I have a <code>UIViewController</code> and I'm navigating from my first view controller to second view controller and I want to change the name of the button shown on the <code>navigationcontroller</code> for going back ....

<pre><code>SecondViewController *secondController = [[SecondViewController alloc]
 initWithNibName:nil
 bundle:NULL]; 
[self.navigationController pushViewController:secondController animated:YES];
</code></pre>

now in the second <code>viewcontroller</code> I want change the name of the button in the <code>navigationController</code>.

How to change the UINavigationController back button name?

Swift

我有一个UIViewController，我正在从我的第一个视图控制器导航到第二个视图控制器，我想更改navigationcontroller上显示的按钮的名称，以便返回...SecondViewController *secondController = [[SecondViewController alloc]
