オブジェクトを作成してObjective-Cで使用するにはどうすればよいですか?

ゲームにBuildboxを使用しています。カスタムリワード広告を実装しました。問題は、リワード動画が開いているときにゲーム音楽が続くことです。ビデオを見た後にミュートまたはミュートを解除したい。

Javaは知っていますが、Objective-CとCocos2dxは得意ではありません。

Objective-Cでオブジェクトを作成し、そのメソッドを使用するにはどうすればよいですか?

Java Equality:

AudioEngine audio = new AudioEngine(); 

audio.pauseAll();

Objective-Cでこのコードを実行するにはどうすればよいですか?

私は問題を解決しました。 AdIntegratorクラスでミュートおよびミュート解除するには、以下を使用します。

これにより、すべてのサウンドがミュートされます。

PTAdController::shared()->setMusic(false);

これにより、すべてのサウンドのミュートが解除されます。

PTAdController::shared()->setMusic(true);
