你可以通过点击storyboard上的空白区域并在右边的工具栏中选择“Show the file inspector”来改变全局色调，你会在工具栏的底部看到“global tint”选项。

你应该加上这一行

 self.navigationController?.navigationBar.topItem?.backBarButtonItem?.tintColor = .black

你只有一个选择把你的后退按钮藏起来，用你自己来做。 然后设置它的颜色。

我这样做了:

self.navigationItem.setHidesBackButton(true, animated: true)
let backbtn = UIBarButtonItem(title: "Back", style:UIBarButtonItemStyle.Plain, target: self, action: "backTapped:")
self.navigationItem.leftBarButtonItem = backbtn
self.navigationItem.leftBarButtonItem?.tintColor = UIColor.grayColor()

你可以通过点击storyboard上的空白区域并在右边的工具栏中选择“Show the file inspector”来改变全局色调，你会在工具栏的底部看到“global tint”选项。

这段代码更改箭头的颜色

self.navigationController.navigationBar.tintColor = UIColor.whiteColor();

如果这不起作用，请使用下面的代码:

self.navigationBar.barStyle = UIBarStyle.Black
self.navigationBar.tintColor = UIColor.whiteColor()

Swift 3 Notes

UIColor.whiteColor()和类似的被简化为UIColor.white

此外，许多以前的隐式可选项已被更改为显式，因此您可能需要:

self.navigationController?.navigationBar =

对于Swift 2.0，要更改导航栏的色调颜色，标题文本和后退按钮的色调颜色更改，请使用AppDelegate.swift中的以下命令

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  // Override point for customization after application launch.


    //Navigation bar tint color change

    UINavigationBar.appearance().barTintColor = UIColor(red: 42/255.0, green: 140/255.0, blue: 166/255.0, alpha: 0.5)

    //Back button tint color change

    UINavigationBar.appearance().barStyle = UIBarStyle.Default
    UINavigationBar.appearance().tintColor =  UIColor(red: 204/255.0, green: 255/255.0, blue: 204/255.0, alpha: 1)

    //Navigation Menu font tint color change

    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor(red: 204/255.0, green: 255/255.0, blue: 204/255.0, alpha: 1), NSFontAttributeName: UIFont(name: "OpenSans-Bold", size: 25)!]//UIColor(red: 42/255.0, green: 140/255.0, blue: 166/255.0, alpha: 1.0)

    UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent


    return true
}
