   You would grab the renderer object off of the CKTextComponentView, and then ask for the text checking result at the point the user touched (https://github.com/facebook/componentkit/blob/master/ComponentTextKit/TextKit/CKTextKitRenderer%2BTextChecking.h#L27).

   Also, please see issue #74

   @ocrickard
   I think it's my bad explain. I had implemented follow issue #74. I can see the text username highlight when I touch on it but the sender is the CKTextComponent with all attributed string (not only the username).
   Example:

   • All text is "abc had do something".
   • I touch on text "abc" and it's highlight.
   • The function 'doSomething:' is fired but the sender is the CKTextComponent "abc had do something."

   What's wrong with my code in viewAttributes:
   {CKComponentActionAttribute(@selector(doSomething:), CKUIControlEventTextViewDidTapText) }

   How can I get the touched text "abc"?

   You would change your doSomething: method to look something like this instead:

   - (void)doSomething:(CKTextComponent *)sender withEvent:(UIEvent *)event
   {
     CKTextComponentView *view = self.component.viewContext.view; // Assumes the tap is being handled by your CKComponentController
     CKTextKitRenderer *renderer = view.renderer;
     UITouch *touch = [[event allTouches] anyObject];
     CGPoint point = [touch locationInView:view];
     NSTextCheckingResult *result = [renderer textCheckingResultAtPoint:point];
     // Profit.
   }
