我的課會失去它的記憶

Question

我有一個類，下面列出了兩種方法。我在一個函數中從另一個類中調用它們。在這個函數中，我新增了我的類，然後調用fireTorpedoContinued。在C＃中一切都會很好，但我開始考慮它。我沒有在任何地方保留課程，似乎沒有什麼能夠阻止它在火力魚雷和火炮繼續之間失去記憶。這個課程有任何東西嗎？還是我需要保留它？例如，execute函數類是否保留類？如果不存在，我會陷入麻煩？

- (void) fireTorpedoContinued 
{ 
    [self.torpedoData.explosionSprite stopAllActions]; 
    CCPlace *placeAction = [CCPlace actionWithPosition:_endPoint]; 
    CCShow *showAction = [CCShow action]; 
    CCCallFunc *callFunctionDeathCheck = [CCCallFunc actionWithTarget:self.deathCheckSelectorTarget selector:self.deathCheckSelector]; 
    CCFadeOut *fadeOutAction = [CCFadeOut actionWithDuration:1.0f]; 
    CCCallFunc *callfunctionAction = [CCCallFunc actionWithTarget:self.completedSelectorTarget selector:self.completedSelector]; 

    CCSequence *sequenceAction = [CCSequence actions:placeAction, showAction, callFunctionDeathCheck, fadeOutAction, callfunctionAction, nil]; 
    [self.torpedoData.explosionSprite runAction:sequenceAction]; 

} 

- (void) fireTorpedo 
{ 
    [self.torpedoData.torpedoSprite stopAllActions]; 
    CCPlace *placeAction = [CCPlace actionWithPosition:_startPoint]; 
    CCShow *showAction = [CCShow action]; 
    CCMoveTo *moving = [CCMoveTo actionWithDuration:2.0f position:_endPoint]; 
    CCHide *hideAction = [CCHide action];  
    CCAction *callCompletedFunction = [CCCallFunc actionWithTarget:self selector:@selector(fireTorpedoContinued)]; 

    CCSequence *sequenceAction = [CCSequence actions:placeAction, showAction, moving, hideAction, callCompletedFunction, nil]; 
    [self.torpedoData.torpedoSprite runAction: sequenceAction]; 
}
