* Introduces RKRequestCache for cacheing responses (supports ETag conditional GET, use cache if available, use cache on error, etc.) closes#75
* Updates to Three20 layer to eliminate need for intermediary TTTableItem classes closes#76
* Fixes to ensure iOS 3.x compatability:
* Switched compiler to Clang
* Updated conditional checks for UIBackgroundTask symbols to ensure runtime safety on iOS 3.x
* Removed unnecessary linkage against UIKit and CoreFoundation from library targets
* Fix for issue where RKRequest objects could become stuck in infinite loop within RKRequestQueue loadNextInQueue if you start
a request and then cancel immediately. On cancel only decrement loadCount if the request has start loading. refs #122
* Removed RestKit from inheritance hierarchy
* Mappings are implemented as concrete classes
* Mapper is much more flexible & powerful
* Much more robust error handling
* Serialization is reimplemented as an object mapping operation
* Added ability to serialize to JSON natively
* Reworked Core Data integration
* Simplified the codebase substantially
* Cleaned up remaining warnings about if (self = [super init])
* RKParamsExample - Highlights multi-part uploads
* RKRequestQueueExample - Working with the request queue
* RKBackgroundRequestExample - Examples of using the background policies for backgrounding requests
* RKReachabilityExample - Shows how to work with the reachability observer
* RKRelationshipMappingExample - Shows how to map related objects from JSON into an object graph
* RKCoreDataExample - Shows the basics of using RestKit's Core Data examples
Also rearranged dispatch of RKRequest delegate method for didStartLoad: to ensure requeue callbacks get invoked in a timely manner. refs #62
* Cleaned up various mismatches in method signatures that were preventing documentation generation
* Removed naked ampersands from comments as they cause XML parser failures during docset generation via appledoc
* Factored out display of alerts into RKAlert interface that hides the differences between UIKit and OS X Cocoa.
* Added macosx to supported platforms to enable build on OS X.
* Configured project to use conditional architectures to enable building on OS X and iOS from the same targets.
* Implemented a bare-bones OS X example app.
* Create `rake build` task for building RestKit against iOS and OS X SDK for quick testing.
Add a new class method that takes a directory parameter, and add a corresponding parameter to the private initializer. The other class methods pass nil for that new parameter. The value for the pathToStoreFile property is now calculated in the initializer, and stored in an instance variable.
Add RKManagedObjectStoreDelegate protocol and a delegate property. Right now, all of the notifications are of errors/failures. Some code has been restructured so that return values are always consulted BEFORE the error parameter is examined.
* Introduce RKObjectMappable#relationshipsToSerialize to define nested relationships to post
* New helper methods for working with relationship serializations.
* Extended Rails router to serialize nested objects according to Rails idioms
Introduces four modes for handling background requests:
* RKRequestBackgroundPolicyNone - The default behavior replicating pre-background behavior. No special action is taken with regards to backgrounding.
* RKRequestBackgroundPolicyCancel - On transition to the background, requests with this policy set will be cancelled automatically and the delegate informed.
* RKRequestBackgroundPolicyContinue - Requests with this policy will be continued in the background after the app has been transitioned.
* RKRequestBackgroundPolicyRequeue - Requests with this policy will be cancelled and then immediately placed onto the queue for processing the next time the app is returned to the foreground.
* Updates YAJL Parser not to raise an exception and crash when it encounters invalid JSON. The other parsers need to be aligned with this behavior and the delegate methods updated. See Pivotal Story: https://www.pivotaltracker.com/story/show/11925617
* Added requestDidCancel: delegate invocation for tracking cancellation of requests.
* Ensure that the request queue timer is cleared during indeterminate deferral of request loads.
