In writing my first iOS app, I found myself reaching out in a few areas of self-discovery regarding the Cocoa Touch framework and what it's capable of, especially in how it compares to Ruby and it's standard library (which is what I've been used to for the past few years of my life). I've grown to love Ruby mixins and monkey-patching, and was delighted to learn that Objective-C has something quite similar: categories. ClassName+CategoryName.{h,m} is all you need, and you can define new class/static and instance methods on an Objective-C class.

One of my other strong preferences is for the Markdown format, and thus I snagged one of the more popular C-based implementations of Markdown (named [Sundown][sun]) and wrote a category around UIWebView for effortlessly displaying a parsed file. This was all made possible in the first place by [an awesome post on Stack Overflow][sta] on using Sundown with Objective-C.

Pundit has a helper method policy_scope that can be used in controllers and views that basicaly a class finder. It is equivalent to:

@posts = policy_scope(Post)
@posts = PostPolicy::Scope.new(current_user, Post).resolve

Using the helper is a nice approach because you dont have to remember what Scope class you need. This is all fine and well on a world where the app is single teanant or the auth logic to reslove scopes needs no other context but the user and the resource that is being requested.

In our world almost all requests are nested under a company context and require a current user to determine membership role to present certain data.
