    <p>I am working on a game and I would like to add a proper slicing feature in it.. so when a sprite sliced, 2 new sprites should be created.. please check <a href="http://cdn1.raywenderlich.com/wp-content/uploads/2012/05/ccc_cutdiagram.png" rel="nofollow noreferrer">here</a></p> <p>At the moment, I am just reducing the size and duplicating the sprites.. Something like this.. Thanks in advance.. </p> <pre><code> - (BOOL) sliceSprite: (Sprite *) sprite withPath: (UIBezierPath *) slicePath { CGSize size = sprite.size; size.width /= 2; size.height /=2; sprite.size = size; sprite.sliced = YES; Sprite *newSprite = [[Sprite alloc] initWithImage: sprite.image]; newSprite.position = sprite.position; newSprite.size = size; newSprite.sliced = YES; newSprite.inView = YES; newSprite.xVelocity = SLICE_SPEEDUP * sprite.yVelocity; newSprite.yVelocity = SLICE_SPEEDUP * sprite.xVelocity; newSprite.angularVelocity = -SLICE_REVUP * sprite.angularVelocity; [sprites addObject: newSprite]; [newSprite release]; sprite.angularVelocity = SLICE_REVUP * sprite.angularVelocity; sprite.xVelocity = -SLICE_SPEEDUP * sprite.xVelocity; sprite.yVelocity = -SLICE_SPEEDUP * sprite.yVelocity; return YES; } - (void) sliceSpritesInSwipePath { CGRect swipeRect = [swipePath bounds]; for (NSUInteger i = 0; i &lt; [sprites count]; i++) { Sprite *sprite = [sprites objectAtIndex: i]; if ([sprite intersectsWithPathInArray: swipePoints inRect: swipeRect]) if ([self sliceSprite: sprite withPath: swipePath]) { [self resetSwipe]; if (![sliceSound isPlaying]) [sliceSound play]; break; } } </code></pre> <p>}</p>

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.
