Text UINavigationBar文本颜色在Swift中

如何在Swift中更改

UINavigationBar

的颜色

大多数在线活动都会说：

[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

我翻译成

let titleDict: NSDictionary = ["NSForegroundColorAttributeName": UIColor.whiteColor()]
self.navigationController.navigationBartitleTextAttributes = titleDict
//self is referring to a UIViewController

---

但它不起作用。我已经改变了背景和按钮的颜色，但是文本的颜色没有改变。有什么想法吗？

使用

NSForegroundColorAttributeName

作为键，而不是

“NSForegroundColorAttributeName”

字符串

let titleDict: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
self.navigationController.navigationBar.titleTextAttributes = titleDict

---

您还可以在

AppDelegate.swift

文件中更改应用程序中的所有

UINavigationController

外观。只需将以下代码放入

应用程序：didFinishLaunchingWithOptions

函数：

var navigationBarAppearace = UINavigationBar.appearance()

navigationBarAppearace.tintColor = UIColor.YourNavigationButtonsColor()  // Back buttons and such
navigationBarAppearace.barTintColor = UIColor.YourBackgroundColor()  // Bar's background color

navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.YourTitleColor()]  // Title's text color

---

信誉：Swift 2.0

self.navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor : UIColor.white]

---

Swift 3+

self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]

Swift 4.0

self.navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor : UIColor.white]

我喜欢：

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
      let navigationBarAppearace = UINavigationBar.appearance()
      navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

     return true
   }

---

Swift 3

UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.white], for: .selected)
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.black], for: .normal)

Swift 4.x：

UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]

---

Swift 4.2

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]

---

Swift 5.1:

    let titleDict: NSDictionary = [NSAttributedString.Key.foregroundColor: UIColor.white]
    navigationController?.navigationBar.titleTextAttributes = titleDict as? [NSAttributedString.Key : Any]

---

根据Swift 1.2更新，语法需要如下

let titleDict:NSDictionary=[NSForegroundColorAttributeName:UIColor.whiteColor（）]self.navigationController！。navigationBar.titleTextAttributes=标题ICT为[NSObject:AnyObject]

根据Swift 2.2:

让标题ICT:NSDictionary=[NSForegroundColorAttributeName:UIColor.whiteColor（）]self.navigationController！。navigationBar.titleTextAttributes=标题为？[String:AnyObject]

有效，谢谢！令人难以置信的可怕，虽然你不能简单地设置一个出口或风格在IB。。。我发现导航控制器很难定制，所以我最终制作了自己的顶栏：/谢谢！工作正常。感谢您在色调/条形色调旁边发表评论，这帮助我意识到我做错了什么，从而结束了我的头撞墙循环D
