LROptional

A simple NSObject category to simplify sending optional messages to objects.

Installation

1. Using CocoaPods

   Add LROptional to your Podfile:

   pod 'LROptional'
   

   Run the following command:

   pod install
   

2. Manually

   Clone the project or add it as a submodule. Drag NSObject+LROptional.h/m folder to your project.

Usage

If you happen to write a lot of this

if ([obj respondsToSelector:@selector(aMessage)])
    [obj aMessage];

You can now replace that with this

[obj.lr_optional aMessage];

Getting rid of conditionals always feels good, but take into account that the second version is slower due to runtime hackery.

Requirements

LROptional requires either iOS 6.0 or Mac OS X 10.8 and ARC.

You can still use LROptional in your non-arc project. Just set -fobjc-arc compiler flag in every source file.
