如何更改UINavigationBar标题的字体和文本颜色 [英] How to change the font and text color of the title of UINavigationBar

问题描述

我想把标题的字体改成Avenir，我想把它变成白色。这是我在 viewDidLoad 方法中的代码：

  UINavigationBar.appearance ）.titleTextAttributes = [NSFontAttributeName：UIFont（name：Avenir，size：20）！] 
 UINavigationBar.appearance（）。titleTextAttributes = [NSForegroundColorAttributeName：UIColor.whiteColor（）] 
  

这段代码只改变标题的颜色，而不是字体。另外，我尝试在应用程序委托文件中实现这一点，但是这不起作用。

以下是我的UINavigationBar：

I希望标题也有Avenir的字体。

解决方案

我使用这个：

更新，这似乎也是需要的：

  self.navigationController？.navigationBar.barStyle = UIBarStyle.Black //然后我设置颜色使用：
 
 self.navigationController？.navigationBar.barTintColor = UIColor（红色：204/255，绿色：47/255，蓝色：40/255，alpha：1.0）//一个可爱的红色
 
 self.navigationController？.navigationBar.tintColor = UIColor.whiteColor（）//用于标题，按钮等
 
让navigationTitleFont = UIFont（name：Avenir ，大小：20）！ 
 
 self.navigationController？.navigationBar.titleTextAttributes = [NSFontAttributeName：navigationTitleFont] 
  

I want to be change the font of the title to Avenir, and I want to make it white. Here is my code in the viewDidLoad method:

UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: UIFont(name: "Avenir", size: 20)!]
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.whiteColor()]

This code only changes the color of the title, not the font. Additionally, I tried implementing this in the App Delegate File, but that did not work.

Here is what my UINavigationBar looks like:

I want the title to have a font of Avenir as well. How do I achieve this?

解决方案

I use this:

Update, it seems this is needed as well:

    self.navigationController?.navigationBar.barStyle       = UIBarStyle.Black // I then set the color using:

    self.navigationController?.navigationBar.barTintColor   = UIColor(red: 204/255, green: 47/255, blue: 40/255, alpha: 1.0) // a lovely red

    self.navigationController?.navigationBar.tintColor = UIColor.whiteColor() // for titles, buttons, etc.

    let navigationTitleFont = UIFont(name: "Avenir", size: 20)!

    self.navigationController?.navigationBar.titleTextAttributes = [NSFontAttributeName: navigationTitleFont]
