Question

我的UITableView有一个自定义单元格，我将显示项目名称like this"below image"的第一个字符

所以我的问题是如何创建它如何通过json从名称数据提取中获取第一个字母选择。

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ProjectTabTableViewCell
   cell.colorViewOutlet.layer.cornerRadius = 25.0
    let projectLst = projectList[indexPath.row]



    let str = projectLst.NameEN



    print(str?.characters.first?.description ?? "");
    projectNameFirst = [str?.characters.first?.description ?? ""]
    print(projectNameFirst)
    cell.wordsLabel?.text = projectNameFirst[indexPath.row]

    cell.nameLabel?.text = projectLst.NameEN
    cell.colorViewOutlet.backgroundColor = .random

    return cell
}

Answer 1

从代码

下面的字符串使用中获取第一个字符

if(isset($_POST['submit']))
{
    foreach($_POST['award_allocations'] as $award_code => $student_codes) {
        printf("Award code: %s allocated to Student codes: %s\n",
            $award_code,
            implode(', ', $student_codes)
        );
    }
    $lock = isset($_POST['lock']) ? true : false;
}

希望这会对你有所帮助
