I'm trying to draw rich-text with images in iOS. I succeed, but there is a serious problem. I used CTRunDelegate to initiate space for each images, but the space only defined in horizontal. I could not specify vertical space size. Because getAscent/getDescent callback functions are not working. (getWidth is working.)
I used code like described in here: http://stackoverflow.com/questions/3246002
What's wrong with my code? Is this a bug?
