TransitionKit is a small Objective-C library providing a block-based API for implementing state machines on iOS and Mac OS X. It supports arbitrary states and events with transition callbacks, NSCopying/NSCoding compliance, and runtime validation of misconfigurations.
Use cases
- implement a state machine in an iOS app
- model object lifecycle states like message read/unread
- manage complex state transitions in Objective-C code
- add transition callbacks and guards to app state logic
- archive and copy state machines with NSCoding
When to choose
- you are building an Objective-C iOS or macOS app that needs finite state machine semantics
- you want a lightweight, dependency-free state machine library with block callbacks
- you need strongly enforced transitions with runtime validation
When to avoid
- you are writing Swift and prefer a Swift-native state machine library
- your project no longer targets legacy iOS/OS X versions supported by this 2017-era release
- you need distributed or hierarchical statecharts rather than simple flat state machines
