iphone - ゲームのプレイ後にアレイをリセットしますか?

Question

私は xcode を使用して iOS でクイズを作成しました。現在、配列から 20 個のランダムな回答を生成するクイズです。ボタンを押して回答が正しいかどうかを確認するときにラベルのテキストを制御します。回答もランダムに生成され、同じテキストで複数の回答がないようにしました。私の問題は、質問がされたときに、配列内のオブジェクトのテキストを「削除」に変更することです。しかし、クイズを行った後にもう一度スタートを押すと、配列には「削除」という文字列を持つ20個のオブジェクトがあります。私の質問は次のとおりです。配列を通常のオブジェクトにリセットするにはどうすればよいですか? ここに私の完全なコードがあります。コメントを無視してください。

ゲームの開始時にarrEuropeのコピーを作成し、ゲームの再開時に復元するか、他の配列を使用して質問に削除済みのマークを付けます。私は個人的にオプション2を使おうとします。

score 0 · Accepted Answer

2 つのオプションが表示されます。

あなたは再び初期化行を呼び出します...

String *arrEurope[][2] =

{

    {@"Eifel.jpg",@"Paris"},
    {@"NotreDame.jpg",@"Paris"},...

または、配列に 3 番目の行を追加し、そこに「削除済み」(私は「使用済み」と呼びます) パラメータを配置します。最後のケースでは、配列をもう一度繰り返して、「削除」を「アクティブ」に戻すことができます
