iOS Question

Is it possible to adjust the baseline in NSAttributedString?

I'd like to slightly modify the y position of a character in an

NSAttributedString
. I know I can subscript (or superscript) using the attribute dictionary:

@{(id)kCTSuperscriptAttributeName: @(-1)}


Unfortunately the shift caused by this is too large in my case. I'm looking for an option to adjust the baseline in 1-point steps.

The attributed string will be displayed in a
UIButton
using
-setAttributedTitle:forState:
.

Answer

As of iOS 7 the NSBaselineOffsetAttributeName attribute has been added.
