UINavigationBar Text Color in Swift

问题

How would I go about changing the color of the UINavigationBar in Swift?

Most things online say to do something like:

[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

Which I translated to

let titleDict: NSDictionary = ["NSForegroundColorAttributeName": UIColor.whiteColor()]
self.navigationController.navigationBartitleTextAttributes = titleDict
//self is referring to a UIViewController

But it doesn't work. I already changed the background and button colors, but the text color doesn't change. Any ideas?

回答1:

Use NSForegroundColorAttributeName as key, not "NSForegroundColorAttributeName" string.

let titleDict: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
self.navigationController.navigationBar.titleTextAttributes = titleDict

You can also change all UINavigationController appearances in your app within the AppDelegate.swift file. Just put the following code within the application:didFinishLaunchingWithOptions function:

var navigationBarAppearace = UINavigationBar.appearance()

navigationBarAppearace.tintColor = UIColor.YourNavigationButtonsColor()  // Back buttons and such
navigationBarAppearace.barTintColor = UIColor.YourBackgroundColor()  // Bar's background color

navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.YourTitleColor()]  // Title's text color
