UINavigationController how to set title
提问by grilix
I have a Controller/View for a generic list of items, that can be extended for displaying a custom list.. Listing and navigation works fine.. but I can't change the title of UINavigationController. In the generic Controller:
我有一个通用项目列表的控制器/视图，可以扩展以显示自定义列表.. 列表和导航工作正常.. 但我无法更改 UINavigationController 的标题。在通用控制器：
- (void)viewDidLoad
{
[super viewDidLoad];
[self.view addSubview: navigationController.view];
}
- (void)setNavigationTitle: (NSString *)title
{
NSLog(@"set title: %@", title); // this works
self.navigationController.title = title; // Nothing works here
}
Then, the extended class does..
然后，扩展类做..
- (void)viewDidLoad
{
[super viewDidLoad];
[self setNavigationTitle: @"Custom list"];
}
The navigationBar still have "Item" as title :(
导航栏仍然有“项目”作为标题:(

In your UIViewControllerthere is a titleproperty and it is that property that will be displayed by the NavigationController. So when pushing a new UIViewControlleronto the navigation stack set the title of that UIViewControllerto whatever is appropriate.
在您的中UIViewController有一个title属性，该属性将由NavigationController. 因此，当将新内容推UIViewController送到导航堆栈时，请将其标题设置UIViewController为适当的值。
In your case it looks like it would be:
在您的情况下，它看起来像：
[self setTitle:@"WhateverTitle"];

For those looking for a Swift solution:
对于那些寻找 Swift 解决方案的人：
class CustomViewController: SuperViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.title = "My Custom Title"
}
}
The titleneeds to be set on the UIViewControllerand not on the UINavigationControllerembedding the view controller.
的title需要被所设定的UIViewController，而不是在UINavigationController嵌入视图控制器。

用
self.title = @"yourTitle";

Swift
迅速
title = "whateverTitle". It's a UIViewControllerinstance property ; invoke anytime.
title = "whateverTitle". 这是一个UIViewController实例属性；随时调用。
From the documentation:
从文档：
Declaration
var title: String? { get set }Discussion
Set the title to a human-readable string that describes the view. If the view controller has a valid navigation item or tab-bar item, assigning a value to this property updates the title text of those objects.
宣言
var title: String? { get set }讨论
将标题设置为描述视图的人类可读字符串。如果视图控制器具有有效的导航项或选项卡栏项，则为该属性赋值会更新这些对象的标题文本。

I know its old thread but thought of sharing this Set the 'self.title' in 'init' method in UIVIewControler derived class, This worked for me!!
我知道它的旧线程，但想到在 UIVIewControler 派生类中的“init”方法中设置“self.title”，这对我有用！
