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
