You should start by investigating the functionality for getting touch input from the Unity documentation. Here's a good place to start:

Try writing the code yourself and ask specific questions if you encounter difficulties.

 

You should actually start with proper thread title like "How do I do ......" instead of just "How?". Keep that in mind in the future.
