objective c - Get word from tap in UITextView

Question

I'm trying to get a word from a tap. The following function's sender is from the UIGesture on the UITextView, sentence.

- (IBAction)printWordSelected:(id)sender {
    NSLog(@"Clicked");

    CGPoint pos = [sender locationInView:self.view];
    UITextView *_tv = sentence;

    NSLog(@"Tap Gesture Coordinates: %.2f %.2f", pos.x, pos.y);

    //eliminate scroll offset
    pos.y += _tv.contentOffset.y;

    //get location in text from textposition at point
    UITextPosition *tapPos = [_tv closestPositionToPoint:pos];

    //fetch the word at this position (or nil, if not available)
    UITextRange * wr = [_tv.tokenizer rangeEnclosingPosition:tapPos withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];

    NSLog(@"WORD: %@", [_tv textInRange:wr]);
}

This is what I already have, but it prints the word out as NULL

Answer 1

"Try changing pos to pos = [sender locationInView:_tv] and then remove the pos.y adjustment. – rmaddy"
