我在这里只找到一个答案。我的问题是我不使用Character
,除了String
是-字符集合。我尝试将其设置为String
。
let name = String(array[indexPath.section][indexPath.row])
但是出现相同的错误无法将类型为'Character'的值分配为类型为'String?'。
这是我的手机:
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"]
}
这里是我的控制器:
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
}
您仅应使用name
来获得indexPath
所需的row
,
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]
