I see for NSAttributedString has a specific attribute for superscript, but I can't find one for subscript. What is the general practice for using NSAttributedString to create a subscript character?

推荐答案

尝试具有负值的NSSuperscriptAttributeName 。

以替换字符串中的[0123456789]字符。

Failing that, the hard way would be to replace [0123456789] characters with [₀₁₂₃₄₅₆₇₈₉] in the string.
