RubyMotion Pairing #1 - Fixing Pods, Target/Action, UITableViews, and more with Murtuza Kutub

The MotionInMotion RubyMotion pairing sessions are focused on doing one-on-one training with developers who are new to RubyMotion, and recording them so other newcomers can learn from it. In this session we work through an error when working with cocoapods due to Command Line Tools not being setup, and then go through some of the basic concepts of iOS development like views, target-action, table views, and delegates & data sources. If you’re not interested in the part at the beginning where we’re fixing the error in cocoapods, skip ahead to 22m 20s in. [more inside]
