我只是想知道...是否可以检查特定用户是否已检查特定城市？
例如，如果 John 之前曾在伦敦和巴黎的一些餐厅登记入住，是否可以从我的应用程序中测试 John 是否去过伦敦或巴黎的某些地方？
谢谢！

Sure, within reason.
- The user authenticates via OAuth2
- You produce a number of recents to the checkin history https://developer.foursquare.com/docs/users/checkins.html - will probably need to use offset and limit to explore ALL of their check-ins
- You will want to write an algorithm to figure out what 'city' means to you - perhaps X miles within the lat/long of the city center? For more detail, use a GeoCode API such as Google's or Bing's http://msdn.microsoft.com/en-us/library/ff701713.aspx
