使用 AsyncDisplayKit 包装嵌套的 ASStackLayoutSpec

Question

将嵌套 ASStackLayoutSpec 与 AsyncDisplayKit 结合使用我正在努力实现这一目标

所以我正在创建一个带有头像的垂直 ASStackLayoutSpec 和另一个带有用户名、时间戳和文本的水平 ASStackLayoutSpec

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)
}

但是结果不是我想的那样

看起来文本变得无穷大，没有正确换行。时间戳也可能在右边出界的某个地方。

我尝试了 .alignItems 和 .justifyContent 的不同组合，但无法正常工作。

您需要在方法layoutSpecThatFits:

中设置您消息节点的width

let messageWidth = UIScreen.main.bounds - (leftSpacing + rightSpacing)
message.style.width = ASDimension(unit: .points, value: messageWidth)

Answer 2

试试这些属性：

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