Proton is a utility framework for Cocoa and Cocoa Touch that provides tools useful for building a powerful model layer.
- A simple and extensible system for bindings, suitable for use on iOS and for replacing Cocoa Bindings on OS X
- Components to make Core Data easier to use, including:
PROCoreDataManager, to manage all the resources associated with a single database
- Support for copying managed objects between contexts
- Support for encoding and decoding managed objects to and from property lists
- Convenience methods on
NSManagedObjectContextso callers have to write less code
- A class for key-value observing that makes it easier to manage the observation of many different objects or key paths
- A couple macros to check key paths at compile time (i.e., fail to build when an invalid key path is used)
- Higher-order functions (map, filter, fold) for all built-in collection classes
- Extensions to
NSUndoManagerto support blocks and make it simpler to manage undo groupings
PROFuture, an extremely fast and simple implementation of block-based futures
All of the above features are unit tested, to validate the typical use cases and detect any future breakage.
Proton has been built with the Model-View-ViewModel architectural pattern in mind. The
PROViewModel abstract class can serve as a base for any application-specific view model layer.
All dependencies can be retrieved by running
git submodule update --init --recursive from the top level of the repository.
- Xcode projects in the repository are configured using prebuilt xcconfigs
- The unit tests for Proton are written using Specta and Expecta
- Logging is implemented using the CocoaLumberjack logging framework
- Parts of libextobjc and SafeDispatch are used in Proton (but are already present in the repository)
