Multi page PDF with CoreText
===

I'm using CoreText to produce a PDF document which contains a series of `NSAttributedString`'s so I create a `CTFrameSetterRef` and give it a frame covering the whole page and then loop through using `CTFrameDraw` to draw the text checking the result of `CTFrameGetVisibleStringRange` to detect when to start a new page. This works great but how can I tell where the text ended? For example the text may stop halfway down the final page and I want to draw some images below. How can I get the position the text ended at?

    CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString((CFAttributedStringRef)notesAttrString);
    do {
        CTFrameRef frame = CTFramesetterCreateFrame(framesetter, currentRange, path, NULL);
        if( frame ) {
            CTFrameDraw(frame, context);

            if( currentRange.location < CFAttributedStringGetLength((CFAttributedStringRef)notesAttrString) ) {
                 UIGraphicsBeginPDFPage();
            } else {
                complete = YES;
            }
        }
    } while( !complete );
