RACSubscriber Protocol Reference

Conforms to	NSObject
Declared in	RACSubscriber.h

Overview

Represents any object which can directly receive values from a RACSignal.

You generally shouldn’t need to implement this protocol. [RACSignal createSignal:], RACSignal’s subscription methods, or RACSubject should work for most uses.

Implementors of this protocol may receive messages and values from multiple threads simultaneously, and so should be thread-safe. Subscribers will also be weakly referenced so implementations must allow that.

Tasks

– sendNext: required method
– sendError: required method
– sendCompleted required method
– didSubscribeWithDisposable: required method

Instance Methods

didSubscribeWithDisposable:

Sends the subscriber a disposable that represents one of its subscriptions.

- (void)didSubscribeWithDisposable:(RACDisposable *)disposable

Discussion

A subscriber may receive multiple disposables if it gets subscribed to multiple signals; however, any error or completed events must terminate all subscriptions.
