ASCollectionNode have a
inverted property of type
BOOL that when set to
YES, will automatically invert the content so that it’s layed out bottom to top, that is the ‘first’ (indexPath 0, 0) node is at the bottom rather than the top as usual. This is extremely covenient for chat/messaging apps, and with AsyncDisplayKit it only takes one property.
When this is enabled, developers only have to take one more step to have full inversion support and that is to adjust the
contentInset of their
ASCollectionNode like so:
CGFloat inset = [self topBarsHeight]; self.tableNode.view.contentInset = UIEdgeInsetsMake(0, 0, inset, 0); self.tableNode.view.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, inset, 0);
See the SocialAppLayout-Inverted example project for more details.
