Ios 单击tableView后隐藏xib的自定义UITableViewCell

我正在尝试使用UITableView以编程方式构建一个带有自定义单元格的tableView，而不使用故事板，但在我完成教程并尝试运行我构建的自定义单元格应用程序之后

自定义单元格显示，但单击tableView后，自定义单元格将隐藏

有人能检查一下我是否遗漏了什么吗？ 或者将xib与编程生成的tableView一起使用是错误的

    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        homeTableView.register(CusTableViewCell.nib, forCellReuseIdentifier: CusTableViewCell.identifier)

        setupTableView()

    }

        let viewModel = HomeViewModel()
        homeTableView.delegate = viewModel
        homeTableView.dataSource = viewModel

        homeTableView.rowHeight = 100

该问题与对

viewModel

的引用较弱有关

将

viewModel

变量放入控制器类，如下所示：

类HomeViewController{
var viewModel:HomeViewModel！
...
func setupTableView（）{
self.viewModel=HomeViewModel（）
...
}
}

是的，你是对的，这是相关的，但在我将viewModel变量更改为

var viewModel:HomeViewModel之后单元格即使未单击也会停止显示，但当我尝试将委托和数据源扩展直接添加到HomeViewController并将表数据源和委托连接到self时，它工作正常？但是使用
fileprivate let viewModel=ProfileViewModel（）
工作正常，谢谢
