DerpKit is a scattered set of categories of functionality that should have been included in Apple's frameworks. It is meant to be unit-tested and have code that is fairly isolated, such that code in here could be extracted for other purposes. The guiding principle is that the code must be simple and widely applicable to be included.

Features

Foundation:

• Block-based KVO
• Percent-encoding on strings
• Base64-encoding on strings and data
• Generating random strings
• Generating HMAC-SHA1 signatures
• Moving UTF8 data between strings and data
• Block-based filtering and mapping on arrays and dictionaries

UIKit:

• View visibility control on view controllers
• Automatic view resizing based on keyboard presence

Usage

The three ways to include DerpKit are:

• Include as a submodule and include as a static library
• Add to the project via CocoaPods
• Pull individual files into your project

DerpKit is based on ARC.
