'subscript(_:)'不可用：不能用 Int 下标字符串 (Swift 5)

Question

我在这里只找到了一个答案。我的问题是我没有使用Character，除了这就是String- 字符集合。我尝试将其设为String可视化;

let name = String(array[indexPath.section][indexPath.row])

但我得到同样的错误无法将"字符"类型的值分配给类型"字符串？

这是我的单元格：

struct SectionStrings {
let sections = ["Stuff", "More Stuff", "Best Stuff"]
}
struct ArrayStrings {
let array = ["Little Stuff", "Bigger Stuff", "Biggest Stuff"]
}
struct DetailArrayStrings {
let detailArray = ["Teeny Stuff", "Teentsie Weentsie Stuff", "Invisible Stuff"]
}

这是我的控制器：

let sections = SectionStrings().sections
var array = ArrayStrings().array
let detailArray = DetailArrayStrings().detailArray
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: reuseIdentifier, for: indexPath) as! SettingsCell
let name = array[indexPath.section][indexPath.row] // errors here
cell.textLabel?.text = name
cell.textLabel?.font = UIFont.boldSystemFont(ofSize: 17)
cell.textLabel?.textColor = .white
let detailName = detailArray[indexPath.section][indexPath.row] // and here
cell.detailTextLabel?.text = detailName
cell.detailTextLabel?.font = UIFont.systemFont(ofSize: 15)
cell.detailTextLabel?.textColor = .white
cell.detailTextLabel?.numberOfLines = 0
cell.selectionStyle = .none
cell.backgroundColor = .black
return cell
}

Answer 1

您应该仅获得使用rowindexPath所需的name，如下所示，

let name = array[indexPath.row]
cell.textLabel?.text = name
cell.textLabel?.font = UIFont.boldSystemFont(ofSize: 17)
cell.textLabel?.textColor = .white
let detailName = detailArray[indexPath.row]
