I am trying to use Helvetica Condensed font in my app. I've overcome problems with it's vertical alignment, by adjusting ascender (as described in this answer).
However, I also have problems with horizontal alignment - the text in UILabel keeps shifting right a bit when text is aligned left (the "length" of the shift depends on how much text is in the label).
I believe it could be solved using the same technique but I don't know which parameter I should adjust.
