I've just published my iOS and Mac OS library for asynchronous image downloading, aptly named AsyncImageDownloader, to CocoaPods.

With CocoaPods installed, setting up your project with the library is easy. Create a file called 'Podfile' in the root of your project, and enter the following contents depending on which platform you're developing for:

# For iOS
platform :ios, '5.0' # 5.0 and up is supported
pod 'AsyncImageDownloader', '~> 1.0.0'

# For Mac OS
platform :osx
pod 'AsyncImageDownloaderOSX', '~> 1.0.0'

With that done, run pod install from the root of your project, and then simply import AsyncImageDownloader:

#import <AsyncImageDownloader.h>

If you run into any trouble, check out CocoaPods.org, and for a tutorial on how to use AsyncImageDownloader, check out this post.
