I am currently using the drawAtPoint method but I would like to specify a global opacity (transparency) to draw the string. Is there a way to do this or should I scan the whole string and make the changes to each character color individually by using the colorWithAlphaComponent method?

You could draw the string to an intermediate image and composite that image with the desired opacity onto the target image.
