準備

開発環境

PC: MacOS X 10.9.4
Xcode: Version 6.1
Ruby: 2.1.3
Rails: 4.1.6

Cocoapodsのインストール

$ rbenv exec gem install cocoapods

プロジェクトディレクトリへ移動

$ cd /path/to/your/xcode/project

Podfileの作成

$ vi Podfile

platform :ios, "7.0"
pod 'AFNetworking', '~> 2.0'
pod "AFNetworkActivityLogger", "~> 2.0"

Cocoapodsのインストール

$ pod setup
Setting up CocoaPods master repo

Fast-forward

  ・・・中略・・・

From https://github.com/CocoaPods/Specs

   ce725a5..4bf3048  master     -> origin/master
Setup completed

外部ライブラリ(AFNetworking等)のインストール

$ pod install
Analyzing dependencies
Downloading dependencies
Installing AFNetworkActivityLogger (2.0.3)
Using AFNetworking (2.4.1)
Generating Pods project
Integrating client project

[!] The use of implicit sources has been deprecated. To continue using all of the sources currently on your machine, add the following to the top of your Podfile:

    source 'https://github.com/CocoaPods/Specs.git'

プロジェクトを開く

Xcodeを起動して、.xcodeprojではなく、.xcworkspaceのプロジェクトファイルを開く。

コーディング

ロギング設定

AppDelegate.swift

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        //ロギング開始
        AFNetworkActivityLogger.sharedLogger().level = .AFLoggerLevelDebug
        AFNetworkActivityLogger.sharedLogger().startLogging()

        return true
    }
}

通信処理

FirstViewController.swift

class FirstViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        NSLog("AFNetwork Starts First Page!!!")

        //リクエスト
        let manager:AFHTTPRequestOperationManager = AFHTTPRequestOperationManager()
        let serializer:AFJSONRequestSerializer = AFJSONRequestSerializer()
        manager.requestSerializer = serializer
        manager.GET("http://localhost:3000/members.json", parameters: nil,
            success: {(operation: AFHTTPRequestOperation!, responsobject: AnyObject!) in
                        println("Success!!")
                        println(responsobject)
                     },
            failure: {(operation: AFHTTPRequestOperation!, error: NSError!) in
                        println("Error!!")
                     }
        )

    }
}
