是否可以制作带有某些字符的NSString作为下标和上标？
[英]Is it possible to make an NSString with some characters as subscripts and superscripts?
问题描述
My app will have chemistry formulas (CO3^2-, H2O, etc), so some of the text in my app will need to have subscripts and superscripts. 
我的应用程序将具有化学式（CO3 ^ 2-，H2O等），因此我的应用程序中的某些文本将需要具有下标和上标。 Is it possible to do this with NSStrings, or is there an alternative/easier way to go about this? 是否可以使用NSStrings执行此操作，或者是否有其他替代方法/更轻松的方法来执行此操作？
