title: How do I utilize OpenLayer (OpenStreetMap) tiles in my mapview iOS 7
body: <p>I started researching maps recently and wanted to know how I could implement the tiles from OpenLayer (which is what I believe openstreetmap is displaying) over my MKMapView. The default sdk doesnt show enough detail for what I want to do. I could ping the servers for the tiles but I keep seeing warning about doing so. So my two problems are 1) how do i get the tiles from the openlayer and overlay them in my mapview and 2) is there a way of getting these tiles ahead of time and just storing them in my app? 
  I am only trying to map a small area (roughly 9 square miles worth). Any suggestions are appreciated</p>
