TSTextMapper

This solution is overwhelmed and overcomplicated. It works but system it is doing it and TextKit has all needed API.

Few classes allow you to map a text inside UILabel and make the text inside tappable, means it adds the ability to detect which word is tapped. It’s both very simple and powerful.

Demo movie tstextmapper.mov is attached in the repo and available on youtube.

How-To

1. Create TSTextMapper.
2. Select one of the few methods how text mapper should work mapTextAndMakeAllTappable or mapTextWithTappableRanges
3. Call textForPoint method when you want to get a word.

---

• mapTextAndMakeAllTappable method makes all text tappable.

• mapTextWithTappableRanges method makes tappable text only in passed ranges.

• textForPoint method returns TSTextProxy. It contains property value.

Debug

If you noticed that something may be wrong with detecting touches (word is not selected or not this word is selected) you can check few things:

• In TSTextMapper is debug method and it's commented inside map method. Put a breakpoint on line debugView.snapshot() in debug method. Method is called for the first time when UILabel is touched.
• In TSTextAnalizer is debug method and it's commented inside mapLines method. Uncomment it. It's called when UILabel is touched for the first time. Entire text should be printed out and the text should be presented in lines the same like it looks inside UILabel.
• In TSTextRefDetector there is debug method which is commented in textRefs method. Uncomment it. All words and whitespaces should be printed out.
