#StackKit

StackKit is a Cocoa framework used to interact with the Stack Exchange API (used by Stack Overflow, Super User, Server Fault, Stack Exchange, and related websites).

It is developed by Dave DeLong. Significant contributions (suggestions, enhancements, etc) have been made by Alex Rozanski, Brock Woolf, Can Berk Güder, Tobias Klonk, and Cory Kilger.

##Current Progress

About 85% of the API is implemented. Chances are it will work, but if it doesn't, please file a bug!

##Using the API

This framework can be used with Mac OS and iPhone OS applications.

###Mac Use the provided StackKit.xcodeproj file to build StackKit as a framework for inclusion in your Mac application.

###iPhone/iPod touch/iPad Use the provided StackKitMobile.xcodeproj file to build StackKit as a static library for inclusion in your mobile application. You must add -ObjC and -all_load to your Other Linker Flags section of your build settings. This ensures that the Categories in StackKit will be loaded with the static library.

###Running the unit tests Change the target to "Unit Tests" and then choose "Build and Run". The StackKit project is set up to only run the tests from the executable (so that they can be debugged), and not during compilation.

##The future

As the API is released and updated by the Stack Overflow team, we will be able to provide an underlying StackKit implementation for such features.

##Endpoint table

The following conventions are being used in this list: Any predicate attribute that begins with "SK" is implied to be a Key Path. Any predicate with a keypath should be constructed in the following format: @"%K = %@", SKSomeKeyPath, someValue##SKQuestionOwner = (123, 456)(123, 456)(tags)(badges)42 = aPropertyaProperty = 42keyNSSortDescriptorNSSortDescriptor * sortByName = [[NSSortDescriptor alloc] initWithKey:SKUserDisplayName ascending:YES];

The symbol can be either a string, a number, or an object of the appropriate type. If the keypath is asking (for example) for a tag, the value can be either the tag's name or an SKTag object. In many cases, you may also pass an array or set of objects of the appropriate type in order to "OR" them together. For example, this predicate will request all questions created either one of the two users: (where is an array or set). A value inside parenthesis (Example: , , etc) denotes a collection (array) of objects. This collection can be a collection of ID's, names, or objects (as appropriate). Keypaths must always be the left expression of a predicate. While is a valid predicate, StackKit would require it to be of the form: . This may change in the future. The values listed as sort values are to be used as the of an . For example:
