我试图改变设置按钮的颜色为白色,但不能让它改变。

这两种方法我都试过:

navigationItem.leftBarButtonItem?.tintColor = UIColor.whiteColor()
navigationItem.backBarButtonItem?.tintColor = UIColor.whiteColor()

但没有变化,它看起来仍然是这样的:

我怎么把那个按钮变成白色?


当前回答

self.navigationController.navigationBar.tintColor = [UIColor whiteColor];

这适用于我,iOS 9.0+

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。

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

这段代码具有魔力。而不是红色,改变它作为你的愿望。

如果你在Settings视图控制器中已经有了后退按钮,你想改变Payment Information视图控制器上后退按钮的颜色为其他颜色,你可以在Settings视图控制器的prepareforsegue中这样做:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
    if segue.identifier == "YourPaymentInformationSegue"
    {
        //Make the back button for "Payment Information" gray:
        self.navigationItem.backBarButtonItem?.tintColor = UIColor.gray               
    }
}

斯威夫特

 override func viewDidLoad() {
     super.viewDidLoad()

 self.navigationController?.navigationBar.tintColor = UIColor.white
 }

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
}
