ios - ASCellNode 内部水平布局显示错误

Question

我使用 AsyncDisplayKit 编写了这段代码：

override open func layoutSpecThatFits(_ constrainedSize: ASSizeRange) -> ASLayoutSpec {

    let horizonTitleDate = ASStackLayoutSpec(direction: .horizontal, spacing: 5, justifyContent: .start, alignItems: ASStackLayoutAlignItems.start, children: [title,space, datetime])
    let verticalMess = ASStackLayoutSpec(direction: .vertical, spacing: 5, justifyContent: .start, alignItems: ASStackLayoutAlignItems.start, children: [horizonTitleDate, desc])
    let horizonMess = ASStackLayoutSpec(direction: .horizontal, spacing: 5, justifyContent: .start, alignItems: ASStackLayoutAlignItems.start, children: [avatar, verticalMess])


    //desc.style.width = ASDimensionMake(constrainedSize.max.width - 100)
    desc.style.alignSelf                 = .stretch
    desc.style.flexGrow                  = 1.0
    desc.style.flexShrink                  = 1.0
    verticalMess.style.alignSelf         = .stretch
    verticalMess.style.flexGrow          = 1.0
    horizonTitleDate.style.alignSelf     = .stretch
    let insets  = UIEdgeInsetsMake(5, 5, 5, 5)
    return ASInsetLayoutSpec(insets: insets, child: horizonMess)

}

我得到这个：

可以看到，黄色的TextNode，比cellNode大，而且不会变成2行，纵向模式下是这样的：

如果我只绘制没有头像的垂直布局，我会获得正确的视图：

怎么了？谢谢！

我没看到flexShrink。verticalMess尝试添加这一行：

    verticalMess.style.flexShrink                  = 1.0
