Can I adjust the baseline in an NSAttributedString without increasing the line height?

In the San Francisco font, brackets are a bit low if they surround numbers. An example from the app I'm making, using an NSAttributedString:

I'd like to increase the baseline for the brackets by a pixel or two, but when I do that using the NSBaselineOffsetAttributeName attribute, the line height is increased by two pixels as well. The text is inside a UITextView, and I really wouldn't like the line height to change. Is there anything I can do?


A possible way to do it is to force the maximum line height with NSParagraphAttributeName.

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init]; [style setMaximumLineHeight:maxHeightWanted]; NSDictionary *parenthesisAttributes = @{NSParagraphStyleAttributeName:style, NSBaselineOffsetAttributeName:@(baselineWanted), NSFontAttributeName:sameFontWithBiggerPointSize};
