Wrapping nested ASStackLayoutSpec with AsyncDisplayKit

Using nested ASStackLayoutSpec with AsyncDisplayKit I am trying to achieve this

enter image description here

So I am creating a vertical ASStackLayoutSpec with avatar and another horizontal ASStackLayoutSpec with the user name and timestamp and text

override func layoutSpecThatFits(_ constrainedSize: ASSizeRange) -> ASLayoutSpec {
    // HEADER with username and timestamp
    let spacer = ASLayoutSpec()
    spacer.style.flexGrow = 1
    let headerStackSpec = ASStackLayoutSpec.horizontal()
    headerStackSpec.spacing = 2
    headerStackSpec.alignItems = .baselineFirst
    headerStackSpec.children = [userNode, spacer, timestampNode]

    // CONTENT - HEADER and text
    let contentStackSpec = ASStackLayoutSpec.vertical()
    contentStackSpec.spacing = 2
    contentStackSpec.children = [headerStackSpec, messageNode]

    // MAIN - avatar and CONTENT
    let mainStackSpec = ASStackLayoutSpec.horizontal()
    mainStackSpec.spacing = 9
    mainStackSpec.children = [avatarNode, contentStackSpec]

    return ASInsetLayoutSpec(insets: UIEdgeInsets(top: 2, left: 10, bottom: 2, right: 10), child: mainStackSpec)
}

But the result is not what I expected

It looks like the text goes to infinity, not properly wraping. The timestamp is also probably somewhere far away on the right out of bounds.

I tried different combinations of .alignItems and .justifyContent but I cannot get it to work.

Solution

  • try these properties:

    contentStackSpec.style.flexShrink = 1
messageNode.style.flexShrink = 1
contentStackSpec.children = [headerStackSpec, messageNode]
