World of Tanks Assistant （WOT Assistant）とWorld of Warplanes Assitant （WOWP Assistant）は、プレイヤーがゲーム内の統計を監視し、戦闘パフォーマンスを友人と比較し、技術的なヘルプ情報にオフラインでアクセスできるようにするコンパニオンアプリケーションです。
WOWP Assistantは比較的最近（2013年11月）登場し、World of Tanksのバージョンは2013年初めにゼロから書き直されました。これは、新しいWargaming Public APIへの移行と同時に行われました。 AssistantとAPI の相互作用のためにiOSライブラリを開発する最も技術的に興味深い側面が、開発者にとって有用であり、Wargaming Developers Contestコンテストの参加者のインスピレーションの源になることを願っています。
必要条件
ライブラリの主な高レベルの要件は、クライアントアプリケーションコードを簡素化するための使いやすさと、支援を提供したり、日常的なタスク（データキャッシングなど）を完全に解決したりする能力です。 以下では、プロジェクトの機能要件と非機能要件のリストを形式化しようとしました。
- 柔軟なデータキャッシング
- 「部分的な」応答のサポート。
- 要求チェーンを処理する便利な方法
- アプリケーションに統合する便利な方法。
- テストによる最大コードカバレッジ。
使用済みのサードパーティソリューション
これらの要件の実装の詳細に戻る前に、使用したライブラリを簡単に説明する価値があります。
AFNetworking
AFNetworkingは、ネットワークデータを操作するための事実上のライブラリ標準です。 その「汎用性」には多くの不要な機能もありますが、独自の機能を作成しないことにしました。
ReactiveCocoa
このライブラリは、iOSの世界に機能的な反応色をもたらします（ Habréの記事 ）。 現在、アシスタントアプリケーションで積極的に使用されています。 最初の段階では、API操作の個別のユニットとして要求を記述する便利な方法のように思えました（これが必要な理由は、以下の要求チェーンのセクションで説明します）。
マントル
iOS Githubチームの別のライブラリ。これにより、データモデルのレイヤーを大幅に簡素化できます。つまり、Webサービスの応答を解析します（READMEの例は非常に参考になります）。 ボーナスとして、すべてのオブジェクトが自動的にサポートを受けます。
