我尝试detailTextLabel
在 tableView 中为 my 设置一个字符串,但它正在返回nil
。我读过其他帖子,我不是第一个,但我不明白我的情况出了什么问题。我正在使用 Swift 4。
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: UITableViewCell = {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") else {
return UITableViewCell(style: UITableViewCellStyle.value1, reuseIdentifier: "Cell")
}
return cell
}()
let filtersRow: Bool = (currentSearchType == .all && indexPath.section == 0)
var titleText: String = ""
if filtersRow == true {
titleText = "Filters"
var detailText: String = ""
if currentFilters.count == 0 {
detailText = "None"
}
else if currentFilters.count == 1 {
detailText = currentFilters.first!
}
else {
detailText = "\(currentFilters.count)"
}
cell.textLabel?.text = titleText /// -> shows 'Filters' as expected
cell.detailTextLabel?.text = detailText /// -> shows nothing
print("Detail text: \(cell.detailTextLabel?.text)") --> returns nil
print("cell.textLabel? \(String(describing: cell.textLabel))") /// --> Optional(<UITAbleViewLabel...>)
print("cell.detailTextLabel? \(String(describing: cell.detailTextLabel))") /// ---> nil
cell.accessoryType = .disclosureIndicator
cell.accessoryType = .disclosureIndicator
return cell
}

我获取单元格的方式肯定有问题,但我在另一个 viewController 中做了同样的事情,而且进展顺利......有人会有想法吗?
