ADBStateMachine 1.0.0

You want to add pod 'ADBStateMachine', '~> 1.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'ADBStateMachine', '~> 1.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try ADBStateMachine

ADBStateMachine 1.0.0

By
Alberto De Bortoli

A proper thread-safe state machine for Objective-C.

Simple usage:

import the files in the Classes folder in your project or install via CocoaPods adding pod "ADBStateMachine" to your Podfile
import ADBStateMachine.h in your class
create a state machine with the initial state and assign it to a property

self.stateMachine = [[ADBStateMachine alloc] initWithInitialState:@"Idle" callbackQueue:nil];

create transitions and add them to the state machine (the state machine will automatically recognize the new states)

ADBStateMachineTransition *t1 = [[ADBStateMachineTransition alloc] initWithEvent:@"start"
                                                                       fromState:@"Idle"
                                                                         toState:@"Started"
                                                                        preBlock:^{
                                                                            NSLog(@"Gonna move from Idle to Started!");
                                                                        }
                                                                       postBlock:^{
                                                                            NSLog(@"Just moved from Idle to Started!");
                                                                        }];

ADBStateMachineTransition *t2 = [[ADBStateMachineTransition alloc] initWithEvent:@"pause"
                                                                       fromState:@"Started"
                                                                         toState:@"Idle"
                                                                        preBlock:nil
                                                                       postBlock:nil];

[stateMachine addTransition:t1];
[stateMachine addTransition:t2];

process events like so

[stateMachine processEvent:@"start"];
[stateMachine processEvent:@"pause"];
