iOS 8中的NavigationBar栏，色调和 Headers 文本颜色-Java 学习之路

142

状态栏中的背景文本仍为黑色 . 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()]

}

在 AppDelegate.swift 中，在 application(_:didFinishLaunchingWithOptions:) 中我提出以下内容：
```
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 = [NSAttributedStringKey.foregroundColor : UIColor.white]
```
对于 titleTextAttributes ，docs说：

您可以在文本属性字典中为 Headers 指定字体，文本颜色，文本阴影颜色和文本阴影偏移

我喜欢亚历克斯的回答 . 如果你想快速尝试一下 ViewController 确保你使用

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]
}

要普遍改变颜色，此代码应位于 NavigationController 的 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，您必须从 ViewController 引用 NavigationController 并在 ViewController 的 viewWillAppear 函数中写入类似的行 .

//在Swift 4中

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

要在 objective-c 中工作，我必须在 viewWillAppear 中将以下行放在我的CustomViewController中 .

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

对于 Swift2.x 这适用：

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

对于 Swift3.x ，这有效：

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

To do this job in storyboard (Interface Builder Inspector)

在 IBDesignable 的帮助下，我们可以为Interface Builder Inspector添加更多选项 UINavigationController 并在故事板上调整它们 . 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storyboard上设置UINavigationController的属性 .

如果要为整个应用程序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

Swift 4.1

将一个func添加到viewDidLoad

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
    }

对于 TitleText TitleText 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]

要么

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