我用过tableview（摸索）。 对于每个部分，我需要从表格视图的每个部分中选择一个单元格。
选择单元格后，我滚动表格视图，然后缺少所选单元格。如何更正... 这是我的代码：-
let questionsModel = questionViewModel.titleForHeaderInSection(atsection:indexPath.section)
print(questionsModel.buttontype)
questionViewModel.button = questionsModel.buttontype
cell.setOptions(Options1: questionViewModel.datafordisplay(atindex: indexPath))
print("Section \(indexPath.section), Row : \(indexPath.row)")
if questionViewModel.button == "2"{
self.selected = 1
cell?.imagebutton.setImage(UIImage(named: "radio_uncheck.png"), for: .normal)
cell.setOptions(Options1: questionViewModel.datafordisplay(atindex: indexPath))
questionViewModel.imagename = "2"
}
else if questionViewModel.button == "1"{
cell?.imagebutton.setImage(UIImage(named: "checkbox_uncheck.png"), for: .normal)
}
else if questionViewModel.button == "3"{
self.selected = 1
/////smileys/////////.................
// cell?.imagebutton.setImage(UIImage(named: "radio_uncheck.png"), for: .normal)
cell.setSmileyRating(Options:questionViewModel.datafordisplay(atindex: indexPath))
questionViewModel.imagename = "3"
}
else if questionViewModel.button == "4"{
self.selected = 1
// print(cell.floatRatingView.rating)
// cell?.imagebutton.setImage(UIImage(named: ""), for: .normal)
cell.setStarRating(Options:questionViewModel.datafordisplay(atindex: indexPath))
questionViewModel.imagename = "4"
}
else if questionViewModel.button == "5"{
self.selected = 1
cell.setOtherOptions(Options:questionViewModel.datafordisplay(atindex: indexPath))
questionViewModel.imagename = "2"
}
if (cell.question.text == "rating_star") {
cell.RatingaddCell = {[weak self] in
if let i = self?.tableview.indexPath(for: $0) {
// print(i)
print("the Selected button is \(cell.tagSelected ?? "")")
print(i)
cell.setStarRating(Options:(self?.questionViewModel.datafordisplay(atindex: indexPath))!)
print(cell.floatRatingView.rating)
let model = self?.questionViewModel.datafordisplay(atindex: indexPath)
print(model?.values ?? "")
print(cell.floatRatingView.rating)
print("Section \(indexPath.section), Row : \(indexPath.row)")

self?.tableview.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)

如何使选定的单元格留在那里？
