Scalable solution for geocoding on iOS
===

I'm working on an iOS app that pulls events from Google Calendar and subsequently generates pins on a map for each event (based on what the event creator fills in for "Location"). The user can select a date range (today, this week, this month, etc.) and see all the events taking place near them over that period.

**Problem 1:** The app is for my local university, so a majority of the locations will be buildings on campus. These buildings have inconsistent addresses that are often difficult to find, so it would be good if the location "Foo Hall" would result in a pin on that building. Google Maps is capable of doing this, however Apple Maps has no knowledge of the buildings on my school campus.

**Problem 2:** In an ideal situation, thousands of students would be using this app. Each time they open the app, they could be viewing dozens of pins. Therefore, I'm worried that I may be pushing the limits imposed by Google's geocoding API (definitely the 2500 request limit, and maybe even the 100,000 request limit for the Business API).

**So my question is...** what would be the best solution for these two problems? Should I create a local database for building names and map them to coordinates? Or is there a way I can overcome the limitations of Google's Geocoding API? Is there a better solution I'm not thinking of?

Thanks for any help!
