# Shift

Shift is just a tiny category that adds a cute little state machine to NSObject. It's also a little bit of a learning project

that turns out to be a little bit useful at times.

## Usage:

It's very simple to use, there really isn't a lot to it.

```objective-c

#import "NSObject+Shift.h"

// First we create an object.

NSString *string = @"Hello world";

// Set a state for it.

string.shiftState = @"inactive";

// Setup some callbacks when that state changes.

[string on:@"active" do:^(id self) {

  NSLog(@"I have become active");

}];

[string before:@"active" do:^(id self) {

  NSLog(@"Going to print this before i become active");

}];

[string after:@"inactive" do:^(id self) {

  NSLog(@"Going to print after state has changed");

}];

[string when:@"inactive" transitionsTo:@"active" do:^(id self) {

  NSLog(@"OMG, My state is transitioning to!!");

}];

[string when:@"active" transitionsFrom:@"inactive" do:^(id self) {

  NSLog(@"OMG, My state is transitioning from!");

}];

string.shiftState = @"active";
