Service Locator for Objective C

Overview

Implementation of Service Locator design pattern for Objective C.

Usage

Register your service for protocol(s) implicitly or explicitly:

[NLServiceLocator registerService:myService];
[NLServiceLocator registerService:myService forProtocol:@protocol(NLSampleService)];

Retrieve services later when you need them by referencing protocol that it conforms and was used for implicit or explicit registration:

id<NLSampleService> myService = [NLServiceLocator serviceForProtocol:@protocol(NLSampleService)];

Done. Enjoy your nicely developed, loosely coupled architecture with an opportunity to replace service by its alternatives in a runtime. Just use it to make your code more managable, or simplify testing by providing mock services with couple of code lines.
