iOS 8中的NavigationBar栏,色调和标题文本颜色

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]
    //nav?.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.orange] // swift 4.2
}

要普遍地改变颜色,此代码应坐在NavigationController的viewDidLoad功能:

class NavigationController: UINavigationController, UIViewControllerTransitioningDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

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

若要更改每个ViewController你就必须引用NavigationController从ViewController写在类似线ViewController的viewWillAppear功能.

在AppDelegate.swift,application(_:didFinishLaunchingWithOptions:)我把以下内容:

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NSAttributedStringKey,文档说:

您可以在文本属性字典中为标题指定字体,文本颜色,文本阴影颜色和文本阴影偏移

//在Swift 4中

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

要在objective-c中工作,我必须viewWillAppear在我的CustomViewController中添加以下行.

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

对于Swift2.x,这适用于:

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

对于Swift3.x,这适用于:

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

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
`

导航barTintColor和tintColor已设置

在storyboard中完成此工作(Interface Builder Inspector)

借助于IBDesignable我们,我们可以为Interface Builder Inspector添加更多选项,UINavigationController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storyboard上设置UINavigationController的属性.

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

更新了swift 4

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