HelloWorldLayerのinitメソッドでこれらすべての行を書き込む代わりに：

 CCTintTo* tint1 = [CCTintTo actionWithDuration:2 red:255 green:0 blue:0];
 CCTintTo* tint2 = [CCTintTo actionWithDuration:2 red:0 green:0 blue:255];
 ....
 CCSequence* sequence = [CCSequence actions:tint1, tint2, nil];
 [label runAction:sequence];

ラベルの色を永久に変更しようとしましたが
、行き詰まりました。整数x、y、zを処理する関連コマンド+を配置する場所がわかりません。update
メソッドでランダム化プロセスを実行しようとしましたが、ラベルへのアクセス、アイデアはありますか？

色合いを毎回ランダムにしたい場合は、CCTintTo内で直接使用することはできませんCCRepeatForever。CCTintToアクションごとに RGB 値を再ランダム化する必要があります。したがって、ブロックを使用してランダム化プロセスをアクション内に埋め込む必要があります。方法は次のとおりです。

// do this in init method

__block void (^changeTint)(CCNode*) = [[^(CCNode *node) {
    GLubyte x = (integer_t)(CCRANDOM_0_1()*255), y = (integer_t)(CCRANDOM_0_1()*255), z = (integer_t)(CCRANDOM_0_1()*255);
    [node runAction:[CCSequence actionOne:[CCTintTo actionWithDuration:2 red:x green:y blue:z]
                                      two:[CCCallBlockN actionWithBlock:changeTint]]];
} copy] autorelease];

changeTint(label);

CCRepeatForeverアクションを見るべきです。名前が示すように、指し示すアクションを永遠に繰り返します。したがって、色を変更している update メソッドを削除し、以前のコードに戻って、それをアクションCCSequenceに埋め込む必要があります。CCRepeatForever

CCTintTo* tint1 = [CCTintTo actionWithDuration:2 red:255 green:0 blue:0];
CCTintTo* tint2 = [CCTintTo actionWithDuration:2 red:0 green:0 blue:255];
....
CCSequence* sequence = [CCSequence actions:tint1, tint2, nil];
CCAction* repeat  = [CCRepeatForever actionWithAction:sequence];
[label runAction:repeat];
