如何将自定义字体和权重（样式）设置为UInavigationbar标题

Question

如何为UINavigationBar标题设置自定义字体名称和自定义字体粗细（字体样式）？

Answer 1

将UIFontDescriptor用作Font Name和Font Size

UIFontDescriptor.fontDescriptorWithSymbolicTraits字体样式（Bold，Italic，...）

Swift 2.x：

let fontDec = UIFontDescriptor(name: "FontName", size: 20)
fontDec.fontDescriptorWithSymbolicTraits(.TraitBold)
let font = UIFont(descriptor: fontDec, size: 20)

self.navigationBar.titleTextAttributes = [
    NSFontAttributeName: font,
    NSForegroundColorAttributeName: UIColor.redColor()]

  

可能是性能问题。

Answer 2

Try this code. Swift 3x

This could be a better approach to set nanvigationBar title font and Style.

    navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.ANY COLOUR, NSFontAttributeName:UIFont(name:"FontName-FontStyle", size: ANY SIZE)!]

Some Font Styles:

    Regular,Bold,BoldItalic,CondensedBlack,CondensedBold,Italic,Light,LightItalic,Thin,ThinItalic,UltraLight,UltraLightItalic

Note: Font style varies from font to font!

Answer 3

快速4倍：

let newFont = UIFont（名称：“ FontName”，大小：15） newFont？.fontDescriptor.withSymbolicTraits（.traitBold）
