async's Introduction

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.

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

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
