MBImageConstants is a simple XCode 5 precompile script that generates precompiler defines corresponding to image sets found in a project's assets. It allows autocompletion for image names and protects against typos.

Requirements

Script works with XCode 5 and project using Images.xcassets to store images. It is a Ruby script so it needs Ruby installed on the build machine.

Installation

Installation is divided at three steps. First, add proper line to your project's Podfile:

pod 'MBImageConstants', :git => 'https://github.com/bananita/MBImageConstants.git', :tag => '0.2.0'

Next, you have to add a new phase to your Project's Build Phases between Check Pods Manifest.lock and Compile Sources. It is simple invocation of ruby with MBImageConstants script:

ruby ${PODS_ROOT}/MBImageConstants/imageconsts.rb ${SRCROOT}

Third, the last step is inserting import to your application prefix file (.pch):

#ifdef __OBJC__
...
#import <MBImageConstants/MBImageConstants.h>
...
#endif

That's all! You can build your project now.

Using

Constants for all image sets will be created with 'image_' prefix. For example:

UIImage* background = [UIImage imageNamed:image_Background];
