我在tableViewCell中有一个具有动态高度的tableView以及其他具有动态高度和单元格比例宽度的ui组件。问题：渲染和滚动外部uitableview时，内部tableViewCells缩小。这是代码：
import UIKit
import WebKit
import SVProgressHUD
class DashboardProgramcell: UITableViewCell, UITableViewDataSource, UITableViewDelegate{
数据，此处为模型。
public var icerikModel:WMPIcerikModel?
static let ID:String = "DashboardProgramcell"
static let turCellPair = (tur: TurID.Program, cellId: ID)
var kListData: WMPArrayOfKatilimciModel?
单元格子视图。
//MainContainer
var container: UIView = {
var container = UIView()
container.translatesAutoresizingMaskIntoConstraints = false
return container
}()
//Left side
var leftContainer: UIView = {
var leftContainer = UIView()
leftContainer.translatesAutoresizingMaskIntoConstraints = false
return leftContainer
}()
var gSaat: UILabel = {
var gSaat = UILabel()
gSaat.translatesAutoresizingMaskIntoConstraints = false
gSaat.numberOfLines = 0
gSaat.font = UIFont.systemFont(ofSize: 11)
return gSaat
}()
var sure: UILabel = {
var sure = UILabel()
sure.translatesAutoresizingMaskIntoConstraints = false
sure.numberOfLines = 0
sure.backgroundColor = ColorHelper.mercury
sure.textAlignment = .center
sure.font = UIFont.systemFont(ofSize: 11)
return sure
}()
var ptad: UITextView = {
var ptad = UITextView()
ptad.textColor = .white
ptad.textAlignment = .center
ptad.isUserInteractionEnabled = false
ptad.isScrollEnabled = false
ptad.translatesAutoresizingMaskIntoConstraints = false
ptad.font = UIFont.systemFont(ofSize: 11)
ptad.textContainerInset = UIEdgeInsets.zero
ptad.textContainer.lineFragmentPadding = 0
return ptad
}()
//Right part
var rightContainer: UIView = {
var rightContainer = UIView()
rightContainer.translatesAutoresizingMaskIntoConstraints = false
return rightContainer
}()
var rightTopTextView: UILabel = {
var rightTopTextView = UILabel()
rightTopTextView.translatesAutoresizingMaskIntoConstraints = false
rightTopTextView.numberOfLines = 0
rightTopTextView.lineBreakMode = NSLineBreakMode.byWordWrapping
rightTopTextView.font = UIFont.systemFont(ofSize: 12)
rightTopTextView.backgroundColor = ColorHelper.arzPopup
return rightTopTextView
}()
这是内部tableView及其约束！
var kList: UITableView = {
var kList = UITableView()
kList.contentMode = .scaleAspectFit
kList.bounces = false
kList.bouncesZoom = false
kList.alwaysBounceVertical = false
kList.translatesAutoresizingMaskIntoConstraints = false
kList.tag = KListCell.TAG
kList.rowHeight = UITableView.automaticDimension
kList.estimatedRowHeight = UITableView.automaticDimension
kList.register(KListCell.self, forCellReuseIdentifier: KListCell.ID)
kList.tableFooterView = UIView(frame: .zero)
return kList
}()
var kListHeightConstraint:NSLayoutConstraint?
var rTopTextViewHeightConstraint:NSLayoutConstraint?

答案 0 :(得分：1)
首先更改此代码：
self.addSubview(container)
到
contentView.addSubview(container)
由于单元格中的视图是根布局，因此应将其添加到contentView中。
