問題
この前、ここの記事 のようにビルド環境を分けようとしてたが、環境を分けるだけで環境別に変数を設定したりするのは一つ一つ書かないといけなかったので、あまりも効率的ではなっかたからもっといい方法があるだろうと思って調べた結果をまとめる。
ソリューション
例えば、Railsにはymlファイルに環境別に変数を設定したり、environmentsフォルダーにconfigの設定をするようにXCodeにもPlistファイルに設定して使う。前の記事 に続いてセッティングしたら良いと。
使い方
1. info.plistを編集
2. Environment.plistを追加
plistの新規作成
3. AppDelegateに設定

import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
let bundle = NSBundle.bundle()
// Configuration取得
let configuration = bundle.infoDictionary!["Configuration"]
// Configurations.plist読み込み
let path = bundle.pathForResource("Environments", ofType: "plist")
let configurations = NSDictionary(contentsOfFile: path!)
// URL取得
let variables = configurations?.objectForKey(configuration!) as! [String : AnyObject]
let urlStr = variables["URL"]
(略)

// Do any additional setup after loading the view, typically from a nib.
self.webView.delegate = self
let initialUrl = NSURL(string: self.appDelegate.urlStr)
let request = NSURLRequest(url:initialUrl as! URL)
self.webView.loadRequest(request as URLRequest)
webView.scrollView.isScrollEnabled = true
}
