CGFloat DegreesToRadiansText(CGFloat degrees) {return degrees * M_PI / 180;};
CGContextSelectFont (context, "Helvetica", 60, kCGEncodingMacRoman);
CGContextSetCharacterSpacing (context, 10);
CGContextSetTextDrawingMode (context, kCGTextFill);
CGContextSetGrayFillColor(context, 0.0, 1.0);
CGAffineTransform myTextTransform = CGAffineTransformRotate(CGAffineTransformScale(CGAffineTransformIdentity, 1.f, -1.f ),(DegreesToRadiansText (-90));
CGContextSetTextMatrix (context, myTextTransform);
CGContextShowTextAtPoint (context, 100, 200, "Quartz 2D", 9);

Taken from Here.

Basically you set the text matrix to a custom transform matrix and then draw. You may want to do a CGContextSave prior to transforming and a CGContextRestore when finished drawing the text.
