README
# 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";
