hey! I am trying to get the UIAttachmentBehavior class thingy to work and it doesn't can some one help?

this is my code

  • (void)viewWillAppear:(BOOL)animated { [super viewDidAppear:animated];

    UIAttachmentBehavior *attach = [[UIAttachmentBehavior alloc]initWithItem:self.imageView attachedToAnchor:self.view.center]; attach.frequency = 0.8; attach.damping = 0.2; attach.length = 7; [self.animator addBehavior:attach];

    UISnapBehavior *snap = [[UISnapBehavior alloc] initWithItem:self.imageView snapToPoint:self.view.center]; [self.animator addBehavior:snap];

}

and for the other bits I am really confused about how to start doing them! (I don't wanna break the app!)

Ben!
