ARC が ARC を蹴っている
cocos 2d をインストールしましたが、ARC を使用したかったので不満でした。よくわからないという問題が発生しています。
Instruments は、GraphicsManager オブジェクトへの参照が 5 つあると言っていますが、そのうちの 4 つしか結論付けることができません。これらの多くを作成してリリースする必要があります。
クラス "RowManager" (CCLayer) は、クラス "GraphicsManager" (CCNode) を呼び出して、これらのオブジェクトを作成します。RowManager はそのメソッドを呼び出して、セレクターを介してオブジェクトを移動します: [self schedule:@selector(row:) interval:.01]
最後に、オブジェクトがポイントに到着すると、メソッド「row1Finished」が呼び出され、オブジェクトへの参照をもう 1 つ作成してから、オブジェクトを呼び出して (死ぬ) 自身の子を削除します。
3 つのアニメーションすべてを停止し、オブジェクトを RowManager から切り離して非表示にすることができますが、dealloc メソッドはまだそれ自体を呼び出しません。私は何を間違っていますか？
arc 以外の cocos2d テンプレートを変換するには、次の手順に従いました。
