表视图很多

Question

我使用tableView仅显示文字。在单元格内部，我使用动态高度UITextView和linkDetection，html文本转换为attributedString。

我正在解析html文本到我的model类中的归属文本：

if let nodeValue = dict["blurb_link"]{
    blurb_link = nodeValue as? String
    let attrString = NSMutableAttributedString(attributedString: (blurb_link?.html2AttributedString)!)
    atr_blurb_link = attrString
}

html2AttributedString extension String中的attributedString从html文本返回textViewBlurbLink.attributedText = model.atr_blurb_link 。

我通过以下方式在细胞亚类中填充我的细胞，

tableView

但是正在发生的问题是，无论何时加载新单元格，tableview都会停留一小段时间，这会使TSNetworkManager.getDataFor(Request: dataRequest, success: {response in //print(response.responseObject!) let model = TSLatestModel.init(WithDictionary: response.responseObject as? [String : Any]) completion(model) tblLatest.reloadData() }, failure: {error in onError(error) }) 滚动有点不稳定且令用户感到不安。

没有图像，没有视频在单元格内没有繁重的任务，可能导致生涩的滚动。请告诉我这种生涩和打嗝滚动的可能原因是什么？

编辑：

我的单元格布局是：

收到回复后，我已经在下面填写了tableView：

cellForRowAtIndexPath

和let modelLatestDetails = model?.data![indexPath.section].items![indexPath.row] cell.setupCellData(model: modelLatestDetails!)

内

setupCellData

在tableViewCell子类textView内，我将文字设置为model class。

EDIT2：

这是我class TSLatestModel: TSModelBase { var data : [LatestListModel]? override init(WithDictionary dictionary: [String : Any]?) { super.init(WithDictionary: dictionary) if let dict = dictionary{ if let nodeValue = dict["data"] { data = [LatestListModel]() for latest in nodeValue as!

Answer 1

可能出现的问题：

1. 单元格布局。我需要看看，如何制作布局并重复使用单元格。
2. 同时解析数据和绘制单元格。 您需要在（tableView.datasource = self or tableView.reloadData()）之前创建所有数据。因此，在重新加载tableView之前，必须准备好[AttributedString]。不要解析cellfoRowAtIndexPath。
中的数据

此外，在单元生命周期内检查tableView为每个单元格调用cellfoRowAtIndexPath一次。
