对于不等高cell的自适应有xib和纯代码方式
参考https://www.jianshu.com/p/2f161f6a310f
- xib和 AutomaticDimension配合使用
- xib和计算高度
- Frame布局和计算高度
- YYKit + CountHeight
- AsyncDisplayKit + CountHeight
这里我也同样采用Frame布局和计算高度
将所有子控件的frame封装在model里并计算高度，图片计算逻辑看代码,以下代码只是暂时粗糙的写个简单demo，只是主要实现逻辑

同样评论回复cell的高度计算
class PXSCommentFrame: NSObject {
var textFrame:CGRect?
var height:CGFloat = 0
var maxW:CGFloat?
var comment:PXSComment? {
didSet {
let textH = self.comment?.text?.getStringHeight(width: kScreenWidth-70, font: 12)
self.textFrame = CGRect.init(x: 10, y: 0, width: kScreenWidth-70, height: textH ?? 0)
height = textH ?? 0
}
}
}
