Collector 1.2.0

You want to add pod 'Collector', '~> 1.2' similar to the following to your Podfile:

target 'MyApp' do
  pod 'Collector', '~> 1.2'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try Collector

Ruby and LINQ-inspired categories on NSArray. Fully tested and documented.

Contributions are welcome. Need something that isn't implemented? Send a pull request!

Features

A safe (prefixed) set of category methods on NSArray.
Fully tested (using the awesome Kiwi library). Take a look at the tests for simple usage examples.
Fully documented (method summaries are displayed when auto-complete is activated in Xcode 5+).

Overview

Using Collector, you get -ct_map:, -ct_reduce: and other Ruby-like methods that remove the need for a lot of array manipulation boilerplate. Eliminate duplicates using -ct_distinct, obtain the objects in a specified range using -ct_objectsInRange:, check if all objects in your array pass a given test using -ct_all:, -ct_any: and -ct_none:, and more.
Some nice extensions to work with NSNumber arrays: -ct_min, -ct_max, -ct_sum and more.
Quick and easy sorting.

API

Note: The following declarations might not be 100% up-to-date with the actual API Collector offers and are displayed here so you can get a feel for the library.
