download

We might face a situation when we need to add action on tapping a particular word from a string on the iPhone screen like a link or a hashtag etc. Now though we can easily add a UITapGestureRecognizer on a UITextView or UILabel, finding the exact tapped word is tricky. Here is how to do this (using UITextView and UILongPressGestureRecognizer) :

i) Add gesture recognizer to text view

  1. UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longPressResponse:)];
  2.     [textViewDescription addGestureRecognizer:longPress];

ii) Handle gesture recognizer

  1. – (void)longPressResponse:(UILongPressGestureRecognizer *)recognizer {
  2.     if (recognizer.state == UIGestureRecognizerStateBegan) {
  3.         CGPoint location = [recognizer locationInView:textViewDescription];
  4.         NSString *tappedWord = [self wordAtPosition:CGPointMake(location.x, location.y)];
