    <p>In my code i've always used <code>spriteA = (__bridge CCSprite *) bodyA-&gt;GetUserData(); //where spriteA is a CCSprite and bodyA is a b2Body.</code> I use it to get whatever sprite is linked to bodyA. My problem is, how do I do this the other way around? I have a sprite and I want to find out what b2Body is linked to it. How do I do this?</p> <p><strong>Edit</strong></p> <p>I don't know wether I set it up right or not, but I'm trying to remove all b2bodies (and sprites) in an array called row4 once there are no more blue objects (objects in row4BlueArray) Here is part of the code in my tick method:</p> <pre><code>//Find the sprite for the b2Bodies else if (bodyA-&gt;GetUserData() != NULL &amp;&amp; bodyB-&gt;GetUserData() != NULL) { spriteA = (__bridge CCSprite *) bodyA-&gt;GetUserData(); spriteB = (__bridge CCSprite *) bodyB-&gt;GetUserData(); contactPositionX = spriteA.position.x; contactPositionY = spriteB.position.y; //If sprite is a member of row 4 (tag 400) if (spriteA.tag == 400 &amp;&amp; spriteB.tag == 8) { [self createExplosionBlue]; [self addTileScore]; [self removeChild:spriteA cleanup:YES]; [self removeChild:spriteB cleanup:YES]; NSLog(@"row 4 count: %d",row4BlueArray.count); //Remove object from another array [row4BlueArray removeLastObject]; toDestroy.insert(bodyA); toDestroy.insert(bodyB); [self unschedule:@selector(tick:)]; ballCount = 0; //if that array is empty, then remove all objects from this array (row4) if (row4BlueArray.count == 0) { for (b2Body * b = _world-&gt;GetBodyList(); b != NULL; b = b-&gt;GetNext()) { Box2DSprite * sprite = (__bridge Box2DSprite*) b-&gt;GetUserData(); b2Body * spriteBody = sprite.body; //not sure how to remove all bodies in an array (row4)` } } } </code></pre>

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.
