    <p>I just download DynamicsCatalog.xcodeproj from the apple developer portal but I'm getting this error:</p> <p>No visible @interface for 'UIAttachmentBejavior' decleares the selector initwititem</p> <p>on this line:</p> <pre><code>UIAttachmentBehavior *attachmentBehavior = [[UIAttachmentBehavior alloc] initWithItem:self.square1 point:attachmentPoint attachedToAnchor:squareCenterPoint]; </code></pre> <p>in APLAttachmentsViewController.m</p> <p>This the context of that line:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; UIDynamicAnimator* animator = [[UIDynamicAnimator alloc] initWithReferenceView:self.view]; UICollisionBehavior* collisionBehavior = [[UICollisionBehavior alloc] initWithItems:@[self.square1]]; CGPoint squareCenterPoint = CGPointMake(self.square1.center.x, self.square1.center.y - 100.0); CGPoint attachmentPoint = CGPointMake(-25.0, -25.0); /* By default, an attachment behavior uses the center of a view. By using a small offset, we get a more interesting effect which will cause the view to have rotation movement when dragging the attachment. */ UIAttachmentBehavior *attachmentBehavior = [[UIAttachmentBehavior alloc] initWithItem:self.square1 point:attachmentPoint attachedToAnchor:squareCenterPoint]; collisionBehavior.translatesReferenceBoundsIntoBoundary = YES; // Show visually the attachment points self.redSquare.center = attachmentBehavior.anchorPoint; self.blueSquare.center = CGPointMake(25.0, 25.0); [animator addBehavior:attachmentBehavior]; self.animator = animator; self.attachmentBehavior = attachmentBehavior; } </code></pre> <p>Any of you knows why or how can I fix this demo code?</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.
