如何在iOS故事板中使用自定义字体来表示动态类型辅助功能大小 [英] How to honor Dynamic Type Accessibility Sizes with a custom font in an iOS storyboard

问题描述

如何使用

解决方案

虽然您无法同时指定自定义字体和通过Storyboard首选文本样式，以编程方式为自定义字体指定动态类型大小并不困难：

  let pointSize = UIFontDescriptor .preferredFontDescriptorWithTextStyle（UIFont TextStyleTitle1）.poi ntSize 
 let customFont = UIFont（name：Chalkboard SE，size：pointSize）
  

当您收到 UIContentSizeCategoryDidChangeNotification 时，请使用相同的代码更新标签的字体。

How can I use the dynamic type text style "Title 1" and set the font face to the built-in font Chalkboard SE for a UILabel in a storyboard?

I need to honor the Dynamic Type size in iOS (Apple has been encouraging this since iOS 7?) I also need to use the built-in font Chalkboard SE, which is not used by default for the "text styles" fonts. I am currently using a custom font as shown in the image, but need the font to change size in accordance with the user's Dynamic Type/Accessibility Sizes preference just as all the Text Styles fonts do. The best Text Styles option is Title 1, but the font/typeface is unacceptable.

解决方案

Although you can't specify both a custom font and a preferred text style via Storyboard, it's not difficult to programmatically specify a dynamic type size for your custom font:

let pointSize  = UIFontDescriptor.preferredFontDescriptorWithTextStyle(UIFont‌​TextStyleTitle1).poi‌​ntSize
let customFont = UIFont(name: "Chalkboard SE", size: pointSize)

When you receive a UIContentSizeCategoryDidChangeNotification, use the same code to update your label's font.
