NavigationBar bar, tint, and title text color in iOS 8
提问by AG1
The background text in the status bar is still black. How do I change the color to white?
状态栏中的背景文字仍然是黑色的。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()]
}

In AppDelegate.swift, in application(_:didFinishLaunchingWithOptions:)I put the following:
在AppDelegate.swift，在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]
(For Swift 4 or earlier use NSAttributedStringKeyinstead of NSAttributedString.Key)
（对于 Swift 4 或更早版本使用NSAttributedStringKey而不是NSAttributedString.Key）
For titleTextAttributes, the docssay:
对于titleTextAttributes，文档说：
You can specify the font, text color, text shadow color, and text shadow offset for the title in the text attributes dictionary
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

I like Alex's answer. If you want something quick to try out in a ViewControllermake sure you use
我喜欢亚历克斯的回答。如果你想快速尝试一些东西，请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
}

To change the color universally, this code should sit in the NavigationController's viewDidLoadfunction:
要普遍更改颜色，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()
}
}
To change it per ViewControlleryou would have to reference the NavigationControllerfrom the ViewControllerand write similar lines in that ViewController's viewWillAppearfunction.
要更改它，ViewController您必须引用NavigationControllerfromViewController并在 thatViewController的viewWillAppear函数中编写类似的行。

To work in objective-cI have to put the following lines in viewWillAppearin my CustomViewController.
要在objective-c 中工作，我必须viewWillAppear在我的CustomViewController 中添加以下几行。
[self.navigationController.navigationBar setBarTintColor:[UIColor whiteColor]];
[self.navigationController.navigationBar setTranslucent:NO];
For Swift2.xthis works:
对于Swift2.x，这有效：
self.navigationController?.navigationBar.barTintColor = UIColor.redColor()
For Swift3.xthis works:
对于Swift3.x，这有效：
self.navigationController?.navigationBar.barTintColor = UIColor.red

To do this job in storyboard (Interface Builder Inspector)
在故事板（Interface Builder Inspector）中完成这项工作
With help of IBDesignable, we can add more options to Interface Builder Inspector for UINavigationControllerand tweak them on storyboard. First, add the following code to your project.
在 的帮助下IBDesignable，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，将以下代码添加到您的项目中。
@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
}
}
}
Then simply set the attributes for UINavigationController on storyboard.
然后只需在情节提要上设置 UINavigationController 的属性。

If you want to set the tint color and bar color for the entire app, the following code can be added to AppDelegate.swift in
如果要为整个应用设置色调颜色和条形颜色，可以在 AppDelegate.swift 中添加以下代码
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)
