我在swift 5中使用它，并为我工作

navigationItem.backBarButtonItem?.tintColor = UIColor(named: "uberRed")

    self.navigationController?.navigationBar.tintColor = UIColor.black // to change the all text color in navigation bar or navigation 
    self.navigationController?.navigationBar.barTintColor = UIColor.white // change the navigation background color
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.black] // To change only navigation bar title text color

你应该这样使用:

navigationController?.navigationBar.barTintColor = .purple
navigationController?.navigationBar.tintColor = .white

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 =

在swift 2.0使用中

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

在AppDelegate.swift中的didFinishLaunchingWithOptions函数中添加以下代码

var navigationBarAppearace = UINavigationBar.appearance()

navigationBarAppearace.tintColor = uicolorFromHex(0xffffff) // White color
navigationBarAppearace.barTintColor = uicolorFromHex(0x034517) // Green shade

// change navigation item title color
navigationBarAppearace.titleTextAttributes =[NSForegroundColorAttributeName:UIColor.whiteColor()]
