COOperation 0.0.3

Maintained by Gleb Novik.

You want to add pod 'COOperation', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'COOperation', '~> 0.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try COOperation

Your service implementation is a cooperation of your core components

COOperation is a component for organizing and structuring the code of your service layer with the help of NSOperation.

	Key Features
🏰	Design beautiful and reusable business logic
🙏	Follow the SOLID principles out of the box
🍏	Use the Compound Operations concept introduced by Apple at WWDC 2015 (Advanced NSOperations)
☑	Write unit and integration tests easily

COOperation is written in Objective-C with full Swift interop support. By the way, we are working on a Swift version!

Usage

Creating your "Chainable Operation"

import Foundation
import CompoundOperations

/// Chainable operation that performs network request
class NetworkRequestChainableOperation: ChainableOperationBase {

    /// Network client (Core-component)
    private let networkClient: NetworkClient

    init(networkClient: NetworkClient) {
        self.networkClient = networkClient

        super.init()
    }

    // MARK: Executing

    override func inputDataClass() -> AnyClass? {
        return NSURLRequest.self
    }

    override func processInputData(inputData: AnyObject?,
                                   completionBlock: ChainableOperationBaseOutputDataBlock) {

        let inputRequest = inputData as! NSURLRequest

        networkClient.performRequest(inputRequest) { (data, error) in
            completionBlock(data, error)
        }
    }
}

Creating your "Compound Operation"

    func obtainDataCompoundOperation(withResultBlock resultBlock: CompoundOperationResultBlock?) -> CompoundOperation {
        let networkRequestOperation = NetworkRequestChainableOperation(networkClient: NetworkClientImplementation())
        let deserializationOperation = DeserializationChainableOperation(deserializer: JSONDeserializer)

        let chainableOperations = [
            networkRequestOperation,
            deserializationOperation
        ]

        let operation = CompoundOperation.defaultCompoundOperation()
        operation.configureWithChainableOperations(chainableOperations,
                                                   resultBlock: resultBlock)

        return operation
    }

Using your "Compound Operation" in your services

    let compoundOperation = obtainDataCompoundOperation { (data, error) in
        // Process the result
    }

    queue.addOperation(compoundOperation) // OR compoundOperation.start()
