Instead of telling what I was trying to do, I decided to show. I was trying to implement the map view that Airbnb did in their iOS app. But I couldn't find the way that they put different prices for each location. Do I need to create the annotation image server-side and push the image to application and show it? Or should I create it in the application side? Since I don't have enough reputation points to put images in here, here is the link of the Airbnb's view.

Thank you.
