Set of Objective-C functions for working with asynchronous blocks

Async

Async is a set of functions for working with asynchronous blocks in Objective-C.

Getting Started

Project/AsyncTests.xcodeproj contains a simple set of tests that demonstrate how to use the library.

Usage

• Include Async.h in your project.
• All Async functions are class-level methods on the Async object.
• Sets of blocks are passed in as an NSArray.
• These blocks always have success and failure callback blocks which conclude the asynchronous function.
• Blocks may additionally receive and return a parameter depending on the method used
• All Async functions have a final success and failure block. If any one block fails, failure() will be called. If not, succcess() is called

Async Functions

• series: run a set of blocks in sequential order
• parallel: run a set of blocks in parallel
• eachSeries: runs a block in series with every item in an array
• eachParallel: runs a block in parallel with every item in an array
• mapParallel: runs a block in parallel with every item in an array, collecting all the return values
• mapSeries: runs a block in series with every item in an array, collecting all the return values
• repeatUntilSuccess: repeat a block until it succeeds or maxAttempts is reached
• waterfall: run a set of blocks in series, passing the return value of a block to the next block

async's Issues

do not allow multiple success calls

mapParallel with empty block array never calls success

Add 'each'

[Async eachParallel:...] and [Async eachSeries:...] would be useful instead of abusing [Async map...] to get the behavior

publish version 0.2.0 on cocoapods

Any insights about when it's planned to publish version 0.2.0 on cocoapods? It has few bug fixes that will be nice to have :)
