cocoapodsセットアップからSwiftyJSON動作確認まで

Posted at

cocoapods インストール

sudo gem update --system
sudo gem install cocoapods

一度ターミナルを開き直す

pod --version
pod setup

参考
http://www.slideshare.net/taichikanako/swift-47934385

プロジェクトで初期設定

cd プロジェクトのディレクトリ
pod init

Podfileが作成されている

SwiftyJSONを使うようにPodfileを修正

https://github.com/SwiftyJSON/SwiftyJSON で書き方を見ながら

# Uncomment this line to define a global platform for your project
# platform :ios, '6.0'

use_frameworks!
pod "SwiftyJSON", ">= 2.2"

target 'MyHttp' do
end

target 'MyHttpTests' do
end

ライブラリのインストール

pod install

Xcodeで
Product > Buildで一度ビルドする.
やらないと、この後のimport SwiftyJSONでエラーになる。

実装

iPhoneでボタンをタッチするとJSONを読み込むというサンプル

ViewController.swift
import UIKit
import SwiftyJSON

class ViewController: UIViewController {

    @IBAction func StartButton(sender: AnyObject) {
        var toJSON: JSON =  ["name": "Jack", "age": 25]
        println(toJSON)
        
        var jsonString = "{\"あああ\": 25}"
        var dataFromString = jsonString.dataUsingEncoding(NSUTF8StringEncoding)
        var json = JSON(data: dataFromString!)
        println(json["あああ"])
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}
