ccTouchesEnded已結束所有操作

Question

所以我一直有一些問題與cctouchesEnded當一觸之間結束它觸發了所有我的按鈕結束行動。我明白爲什麼會發生這種情況，但爲了解決這個問題，我不確定要做什麼。如果我要爲按鈕創建一個類併爲每個新按鈕創建一個新類的實例，那麼每個按鈕都將是分開的嗎？如果是的話，有沒有一個很好的例子來說明如何使用類在cocos2d中創建簡單的按鈕？任何幫助，將不勝感激。這是我目前如何使用按鈕。

我要張貼在一個項目中使用今年早些時候（cocos2d的，Objective-C的），「雙觸摸按鍵」的一個例子。您在創建時將其傳遞給CCNode（例如CCSprite），當您按下它並釋放它時，它將執行一系列操作（請參閱.mm文件）。它會執行向上和向下的選擇器（我正在使用它作爲一個火災按鈕...需要支持按下按鈕）。如果您需要這種方式，您應該可以修改它以執行單一操作。

DoubleActionButton.h

#import <Foundation/Foundation.h>

     // This button executes an action on the NODE, when the button is pressed down and when the 
     // button is released.

    dblBtn.position = ccp(leftEdge,botEdge); 
    [self addChild:dblBtn];
