Getting wrapped height from CoreText (Core Text->General)
You're drawing wrapped text in a simple rectangle in CoreText, and you want to figure out the height of it. (fixed width, flexible height).
CTFramesetterRef fsetter = CTFramesetterCreateWithAttributedString (attrString);
CFRange fitRange;
CGSize frameSize =
CTFramesetterSuggestFrameSizeWithConstraints (fsetter,
CFRangeMake (0, 0),
NULL, // frame attributes
CGSizeMake (rect.size.width,
CGFLOAT_MAX),
&fitRange);
fitRange is the range of characters that fit in. Given a height of CGFLOAT_MAX, this should be the entire string. frameSize is the width and height the text will be wrapped in. A { 0, 0} range means to use the whole string.
