I've been searching high and low and can't figure out how to do this. Lets say I have a string like this:
NSString *string = @"&foo !foo";
What I'm trying to do is differentiate between the two foos (sounds funny haha) inside a text view. When I click on one, I want to know which (& or !) comes before it. Here's how I'm getting the word:
UITapGestureRecognizer *recognizer = (UITapGestureRecognizer *)sender;
UITextView *TV = (UITextView*)recognizer.view;
CGPoint location = [recognizer locationInView:TV];
location.y += TV.contentOffset.y;
UITextPosition *tapPosition = [TV closestPositionToPoint:CGPointMake(location.x, location.y)];
UITextRange *textRange = [TV.tokenizer rangeEnclosingPosition:tapPosition
withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];
NSString *tappedWord = [TV textInRange:textRange];
I can't figure out how to get the previous character. TV.tokenizer
UITextGranularityCharacter
only gets the closest letter, not the symbol. Any solutions for this?
