    <p>I am making a box2d app for the iphone using cocos2d. I am trying to switch my CCLayer going from my HelloWorldLayer to my HomeScene and I get an error "Thread 1: Program received signal: "EXC_BAD_ACCESS"." It gives me that error when I try to call [super dealloc] in my dealloc method for my HelloWorldLayer. Please Help. Here is my .h and .mm</p> <pre><code>@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 </code></pre> <p>Here is my .mm where I deallocate</p> <pre><code>// 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]; } </code></pre>

    1. COAre you calling release on your layer? Many Cocos objects pretty much default to being autorelase so if you call say removeChild for your layer I believe that should be enough to deallocate it implicitly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
