title: How to find if two google map routes are being intersected in an IOS project
body: <p>I want to achieve the following and I am unaware whether it is possible or not. I am having two points on a road (imagine like a finishing line - they are the two edges of the pavements - they are in a straight line) and I want to check whether a user's route has passed between these points.</p>
  
  <p>So I thought, I can do something like this:</p>
  
  <ol>
  <li>get the route between these two points (they are quite near - the road is 20 m wide at most)</li>
  <li>get the users route</li>
  <li>check if these routes are interecting, if there is any crossing between them.</li>
  </ol>
  
  <p>If it was pure geometry, it would be easy. I am having two lines and I want to know if there is any intersection between them.</p>
  
  <p>I want to use the following in an IOS project, if it makes any difference. For example, I thought that maybe there is a programmatically way of drawing the MKPolylines and see if there is intersection. I do not want to see it visually, I just need it programmatically.</p>
  
  <p>Is it possible? Can you suggest me anything else?</p>
