问题描述

我想从AppDelegate全局更改整个应用程序的UINavigationBar颜色.为此,我这样做:

I want to change UINavigationBar color globally for the whole application from the AppDelegate. For it I do:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
UINavigationBar.appearance().tintColor = UIColor(red: 63, green: 172, blue: 236, alpha: 1)
}

但是,我不知道为什么,它不会改变导航栏的颜色.

but, I do not know why, it doesn't change the color of my Navigation bar.

我将导航栏连接为Editor > Embed In > Navigation Controller

如何为NavBar设置颜色?

How can I set the color for NavBar?

推荐答案

设置barTintColor

UINavigationBar.appearance().barTintColor = UIColor(red: 63.0/255.0, green: 172.0/255.0, blue: 236.0/255.0, alpha: 1.0)

我认为您忘了除以255

I think you forgot to divide with 255

用于关闭translucent.在您的第一个根控制器中,执行以下操作.

For turn off the translucent. In your first root controller do it as follows.

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController!.navigationBar.translucent = false
}

快捷键3:

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController!.navigationBar.isTranslucent = false
}

我的输出:
