¿Hay algún Tutorial Restkit 2.0 como raywenderlich?

Question

estoy aprendiendo restiit api. Encontré un muy buen tutorial de Raywenderlich restkit. Pero está integrado con Restkit 0.10.1. Y quiero aprender un RestKit-0.20.0-pre6. Si alguien tiene un buen tutorial como este en iOS. Por favor comparte. Gracias por adelantado.

Answer 1

¡Hice una pregunta similar y logré resolverlo justo cuando alguien me dio la respuesta! ¡Típico!

Answer 2

Encontré el siguiente código para trabajar con RestKit 0.20.

El otro código que se encuentra en el tutorial de RayWenderlich para Location.m, Location.m, Venue.m y Venue.h aún debe estar bien.
