Bus transportation is a safer and more eco-friendly mode of transportation for Richmond residents to use while enjoying the city's great culture and local events.

The 2BNB app launched in August 2011 and has had two minor and one major version updates. The newest version fully supports iOS 6 routing with the new Maps app and adds an iPad user interface. Over 20,000 riders have safely traveled throughout the Richmond Metro area using the 2BNB app.

2BNB communicates with a RESTful backend with JSON over HTTP. It heavily uses UIApperance and MapKit for its user interface and Google Directions to provide the data for iOS 6 routing.

This application is not affiliated with 2BNB, but is offered as an aid to riders who want to use the service.

  • RT @beccadax: @fbartho @grynspan os_unfair_lock was designed for ObjC and is super-awkward to use from Swift because in Swift, the `&` operator is allowed to create a temporary copy, and locking a *copy* of a lock is useless. You have to allocate and manipulate it through UnsafePointers to prevent copying. 19 days ago
