私はあなたのアドワイズが必要です:私は2つのクラスを持っています.最初に2番目のオブジェクトを初期化し、次のような2番目のクラスの関数を使用したいと思います:

最初のクラスでは、2番目のオブジェクトを初期化します

self.keys = [KeyLayer node];
self.keys.position = CGPointMake(-0.f, -0.f);
[self addChild:self.keys z:1];

そして、次のようなself.keysオブジェクトに2番目のクラスのclose関数を適用したい:

[self.keys.sprite self.keys.close];

しかし、それは機能しません

セカンドクラス

#import <Foundation/Foundation.h>
#import "cocos2d.h"

@interface KeyLayer : CCLayer  {

    CCLabelTTF *_label;
    CCAction *_actionOpen;
    CCAction *_actionClose;
    CCSprite *_sprite;
    CCAnimation *_animation;

}
@property (nonatomic, retain) CCSprite *sprite;
@property (nonatomic, retain) CCAction *actionOpen;
@property (nonatomic, retain) CCAction *actionClose;
@property (nonatomic, retain) CCAnimation *animation;
@property (nonatomic, retain) CCLabelTTF *label;

まず第一に、これはオブジェクトのメソッドを呼び出す方法ではありません。

[self.keys.sprite self.keys.close]; // even if self.keys.close was defined this is not how you call it

さて、スプライトで closeKey を呼び出したいと思うので、次のようにして簡単に実行できます。

[self.keys closeKey]; // self.keys is your object and closeKey is the method you desire to call on your object.
