Swift中的UINavigationBar文本颜色 [英] UINavigationBar Text Color in Swift

问题描述

如何在Swift中更改UINavigationBar的颜色?

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

大多数在线事情都说要做类似的事情:

Most things online say to do something like:

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

我翻译为

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

但是它不起作用.我已经更改了背景和按钮的颜色，但是文本的颜色没有改变.有什么想法吗?

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

推荐答案

使用NSForegroundColorAttributeName作为键，而不是"NSForegroundColorAttributeName"字符串.

Use NSForegroundColorAttributeName as key, not "NSForegroundColorAttributeName" string.

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