我在6Plus上出现这样的问题，原因在于center位置不对了，我只需要垂直方向。所以我修改了一下： UIAttachmentBehavior *spring = [[UIAttachmentBehavior alloc] initWithItem:attribute attachedToAnchor:attribute.center]; ---> UIAttachmentBehavior *spring = [[UIAttachmentBehavior alloc] initWithItem:attribute attachedToAnchor:CGPointMake(self.collectionView.bounds.size.width/2, attribute.center.y)]; 和： item.center = center; ---> item.center = CGPointMake(self.collectionView.bounds.size.width/2, center.y);
