Alex,
I can draw the text using NSString's drawing method. But I am not clear how to get the tapped String using touch point or GCRect. I don't any direct method to get the String by passing CGPoint or CGRect.
I was able to successfully implement this feature by creating CATextLayer for each word and put all the layers as a sublayer of UIView's layer object. When user tapped on this View, hitTest method would return the Layer which was tapped. Using the Layer Object i was able to get the tapped string.
Does this approach cause any performance or memory related issue. since i am creating CATextLayer object for each word.
Thanks
Sasikumar
