【iOS】Dropbox iOS13対応

Last updated at Posted at 2020-04-01

#はじめに
・iOS13用にDropboxを対応したところ、ハマったので備忘録として記載。

#環境
xcode11.0
swift 5.0.1
iOS13

#これまで
・チュートリアル通りに進むと

AppDelegate.swift
  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
      if let authResult = DropboxClientsManager.handleRedirectURL(url) {
          switch authResult {
          case .success:
              print("Success! User is logged into Dropbox.")
          case .cancel:
              print("Authorization flow was manually canceled by user!")
          case .error(_, let description):
              print("Error: \(description)")
          }
      }
      return true
  }

と記載していた。
iOS13ではSceneDelegate.swiftに移譲された為、変更が必要になる。

#これから
・SceneDelegate.swiftへ以下を記載。

SceneDelegate.swift

    func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>)
    {

      // コールバックで来たURLの取得
      guard let url = URLContexts.first?.url else {
          return
      }

      if let authResult = DropboxClientsManager.handleRedirectURL(url) {
          switch authResult {
          case .success:
              print("Success! User is logged into Dropbox.")
          case .cancel:
              print("Authorization flow was manually canceled by user!")
          case .error(_, let description):
              print("Error: \(description)")
          }
      }
      return
  }

#まとめ
・iOS13とそれ以前のiOSを対応させるように作成した為、AppDelegateが原因であることに気づくのに時間がかかった。
大型アップデート後の情報収集は怠ってはならない教訓になりました。
