如何取消分配CCLayer

我正在使用cocos2d爲iPhone製作box2d應用程序。我試圖將我的CCLayer從我的HelloWorldLayer切換到我的HomeScene，並且出現錯誤「線程1：程序接收到的信號：」EXC_BAD_ACCESS「。」當我嘗試在我的HelloWorldLayer的dealloc方法中調用[super dealloc]時，它給了我這個錯誤。請幫忙。這是我的.h和.mm如何取消分配CCLayer

@interface HelloWorldLayer : CCLayer 
{ 
    b2World *world; 
    Cannon *cannon1; 
    Cannon *cannon2; 
    Cannonball *cannonball1; 
    Cannonball *cannonball2; 
    float theMass; 
    float theMass2; 
    CCSprite *sunBack; 
    b2Vec2 cannon1Pos; 
    b2Vec2 cannon2Pos; 
    CCMenuItemSprite *pauseBut; 
    CCMenuItemSprite *playBut; 
    CCMenu *pauseMenu; 
} 
@property(nonatomic)b2Vec2 cannon1Pos; 
@property(nonatomic)b2Vec2 cannon2Pos; 

@property(nonatomic, retain)CCSprite *sunBack; 
@property(nonatomic, retain)Cannon *cannon1; 
@property(nonatomic, retain)Cannon *cannon2; 
@property(nonatomic, retain)Cannonball *cannonball1; 
@property(nonatomic, retain)Cannonball *cannonball2; 
@property(nonatomic, retain)CCMenu *pauseMenu; 

// returns a CCScene that contains the HelloWorldLayer as the only child 
+(CCScene *) scene; 
+(HelloWorldLayer *) sharedLayer; 
-(void)createMonkeys; 
-(void)restartGame; 
-(void)playGame; 
-(void)pauseGame; 
-(CCSpriteBatchNode*)getSpriteBatch; 
-(void)goToHome; 

@end

這裏是我的.mm，我取消分配

// on "dealloc" you need to release all your retained objects 
- (void) dealloc 
{ 
    // in case you have something to dealloc, do it in this method 
    delete world; 
    world = NULL; 
    [[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames]; 
    [cannon1 removeFromParentAndCleanup:YES]; 
    [cannon2 removeFromParentAndCleanup:YES]; 
    [cannonball1 removeFromParentAndCleanup:YES]; 
    [cannonball2 removeFromParentAndCleanup:YES]; 

    // don't forget to call "super dealloc" 
    [super dealloc]; 
}

的dealloc的你在你的圖層上調用發佈？很多Cocos對象都默認爲autorelase，所以如果你爲你的圖層調用removeChild，我相信這應該足以隱式地釋放它。 –

你可以試試這個，而不是你已經使用

-(void) dealloc 
{ 
delete world; 
world = NULL; 
cannon1 = NULL; 
cannon2 = NULL; 
cannonball1 = NULL; 
cannonball2 = NULL; 
[super dealloc]; 
}
