iOS 8中的NavigationBar栏，色调和标题文本颜色

Question

状态栏中的背景文字仍为黑色。如何将颜色更改为白色？

// io8, swift, Xcode 6.0.1 
override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.navigationBar.barTintColor = UIColor.blackColor()
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orangeColor()]

}

Answer 1

在 AppDelegate.swift 中，application(_:didFinishLaunchingWithOptions:)我提出以下内容：

UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]

（对于Swift 4或更早版本，请使用NSAttributedStringKey代替NSAttributedString.Key）

对于titleTextAttributes，docs说：

  

您可以指定字体，文本颜色，文本阴影颜色和文本   文本属性字典中标题的阴影偏移

我喜欢亚历克斯的回答。如果您想在ViewController中快速尝试一下，请确保使用

viewWillAppear()
override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    var nav = self.navigationController?.navigationBar
    nav?.barStyle = UIBarStyle.Black
    nav?.tintColor = UIColor.white
    nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]
    //nav?.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.orange] // swift 4.2
}

Answer 3

要普遍改变颜色，此代码应位于NavigationController viewDidLoad函数中：

class NavigationController: UINavigationController, UIViewControllerTransitioningDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Status bar white font
        self.navigationBar.barStyle = UIBarStyle.Black
        self.navigationBar.tintColor = UIColor.whiteColor()
    }
}

要根据ViewController进行更改，您必须引用NavigationController中的ViewController并在ViewController viewWillAppear中写出类似的行功能。

Answer 4

//在Swift 4中

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

Answer 5

要在 objective-c 中工作，我必须在我的CustomViewController中将viewWillAppear中的以下行放入。

[self.navigationController.navigationBar setBarTintColor:[UIColor whiteColor]];
[self.navigationController.navigationBar setTranslucent:NO];

对于 Swift2.x ，这可行：

self.navigationController?.navigationBar.barTintColor = UIColor.redColor()

对于 Swift3.x ，这有效：

self.navigationController?.navigationBar.barTintColor = UIColor.red

Answer 6

在故事板（Interface Builder Inspector）中执行此作业

借助IBDesignable，我们可以为UINavigationController的Interface Builder Inspector添加更多选项，并在故事板上进行调整。首先，将以下代码添加到项目中。

@IBDesignable extension UINavigationController {
    @IBInspectable var barTintColor: UIColor? {
        set {
            navigationBar.barTintColor = newValue
        }
        get {
            guard  let color = navigationBar.barTintColor else { return nil }
            return color
        }
    }

    @IBInspectable var tintColor: UIColor? {
        set {
            navigationBar.tintColor = newValue
        }
        get {
            guard  let color = navigationBar.tintColor else { return nil }
            return color
        }
    }

    @IBInspectable var titleColor: UIColor? {
        set {
            guard let color = newValue else { return }
            navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: color]
        }
        get {
            return navigationBar.titleTextAttributes?["NSForegroundColorAttributeName"] as? UIColor
        }
    }
}

然后只需在故事板上设置UINavigationController的属性。

如果要为整个应用设置色调颜色和条形颜色，可以将以下代码添加到AppDelegate.swift中

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

    var navigationBarAppearace = UINavigationBar.appearance()

    navigationBarAppearace.tintColor = UIColor(red:1.00, green:1.00, blue:1.00, alpha:1.0)
    navigationBarAppearace.barTintColor = UIColor(red:0.76, green:0.40, blue:0.40, alpha:1.0)
    navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
    return true
`

Navigation barTintColor and tintColor is set

更新了swift 4

override func viewDidLoad() {
    super.viewDidLoad()
        self.navigationController?.navigationBar.tintColor = UIColor.blue
        self.navigationController?.navigationBar.barStyle = UIBarStyle.black
}

Answer 9

在Swift 4.1和Xcode 9.4.1中

self.navigationItem.title = "your name"
let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
navigationController?.navigationBar.titleTextAttributes = textAttributes

Answer 10

Swift 4

let el = await page.$x('//*[@id="readium-right-panel"]/ul/li[1]');

Answer 11

Swift 4.1

向viewDidLoad添加func

override func viewDidLoad() {
  super.viewDidLoad()

  setup()
}   

在setup()函数中添加：

func setup() {

        navigationController?.navigationBar.prefersLargeTitles = true
        navigationController?.navigationBar.barStyle = .blackOpaque
        navigationItem.title = "YOUR_TITLE_HERE"
        navigationController?.navigationBar.barTintColor = .black
        let attributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
        navigationController?.navigationBar.largeTitleTextAttributes = attributes
    }

Answer 12

在Swift 4.2版中将导航栏标题的文本颜色设置为白色：

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

Answer 13

Swift 5.1

仅复制并粘贴到ViewDidLoad()中，并根据需要更改其大小。 复制和粘贴之前，在屏幕顶部添加导航栏。

navigationController?.navigationBar.titleTextAttributes = [ NSAttributedString.Key.font: UIFont(name: "TitilliumWeb-Bold.ttf", size: 16.0)!, NSAttributedString.Key.foregroundColor: UIColor.white]

如果它不起作用，则可以尝试仅更改其文本颜色

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

Answer 14

对于TitleText处NavigationBar的自定义颜色，这里是Swift 3的简单和简短代码：

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

或

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

Answer 15

阿尔伯特答案的快速4.2版本-

UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor : UIColor.white]

Answer 16

在Swift 3中，这有效：

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

Answer 17

在Swift 4.2中

var nav = self.navigationController?.navigationBar
nav?.barStyle = UIBarStyle.Black
nav?.tintColor = UIColor.white
nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]

Answer 18

快速浏览Swift 3.2（不是Swift 4.0）

    self.navigationController?.navigationItem.largeTitleDisplayMode = .always
    self.navigationController?.navigationBar.prefersLargeTitles = true
    self.navigationController?.navigationBar.largeTitleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

    // unconfirmed but I assume this works:
    self.navigationController?.navigationBar.barTintColor = UIColor.white
    self.navigationController?.navigationBar.barStyle = UIBarStyle.black
