Adam Block - Off the Rails: Why it's Time to Go Beyond 'MVC' for Cocoa

Looking for Contract Work? Email [masked] for details.

This month Adam Block will be presenting his talk "Off the Rails: Why it's Time to Go Beyond 'MVC' for Cocoa Development". The talk will cover how the MVC pattern is implemented in Cocoa, and why it breaks down at the UIViewController. Adam will review the VC's weaknesses -- code reuse, separation of concerns, testing -- before talking about how ditching MVC and rethinking iOS projects in terms of Model-View-ViewModel can help developers escape the VC trap. 

Adam is an iOS engineer and leads the product team at Breeze, which brings mobile software-as-a-service to home service pros like plumbers, locksmiths, and handymen.

Interested in Speaking or Hosting NSMeetup? 

Please reach out to Steve Derico if you are interested. We are looking for hosts for upcoming events with seating for at least 100 people, in the San Francisco city limits. Every month, we meet for some tech talks and free beer. iOS developers can present their newest project/library and then we'll have an hour of networking and drinks. Topics will stay specific to Objective-C and iOS. Open-source projects are highly encouraged.

We cannot hold the door open for everyone once the talk has started. You must be RSVP'd to enter the event.

    For those who didn't see, the most recent issue of includes an article by Ash Fuller on MVVM. It's a very clear articulation of a number of themes I covered in my talk.

    Great talk! I was wondering if anyone has experimented with using a centralized routing (perhaps based on a url scheme) similar to rails' routes.rb? This would give you the added benefit of being able to support deep linking (for example from a push notification) right out of the box.

      we use JLRoutes to map URLs to VCs. We also use it to forward arguments (you can call other methods in the handler)

    The repo with sample code from last night presentation is here:

    To expand on what I was referencing last night, I made a repo showing how you can do KVO on the contents of an array (like what objects are inserted at what indexes)

    This will allow you to avoid having an 'updateList' int that you increment, and b/c you get the index of the updated object, you can property implement UITableView methods like `insertRowsAtIndexPaths:withRowAnimation:`

    Haven't used this in awhile, so its worth exploring to see if there are some bad edge cases or something.

    This topic is fascinating and very timely. Really looking forward to this. To anyone else who is generally interested in the topic, Fowler's essay on GUI architectures is a good survey:
