Objective c 开关函数中的预期表达式错误-目标-C

我正在学习开关函数，所以我更改了if和else语句，如下所示：

但它给了我“预期表达式”的错误

为什么?

//这个是正确的

if (indexPath.section == 0) {
    cell.textLabel.text = FileANames[indexPath.row];
    cell.detailTextLabel.text = FileADetails[FileANames[indexPath.row]];
}

else if (indexPath.section == 1) {
    cell.textLabel.text = FileBNames[indexPath.row];
    cell.detailTextLabel.text = FileBDetails[FileBNames[indexPath.row]];
}

else if (indexPath.section == 2) {
    cell.textLabel.text = FileCNames[indexPath.row];
    cell.detailTextLabel.text = FileCDetails[FileCNames[indexPath.row]];
}

return cell;
}

谢谢。

应该是这个

switch (indexPath.section) {

    case 0:  {
        cell.textLabel.text = FileANames[indexPath.row];
        cell.detailTextLabel.text = FileADetails[FileANames[indexPath.row]];
        break;
    }

    case 1: {
        cell.textLabel.text = FileBNames[indexPath.row];
        cell.detailTextLabel.text = FileBDetails[FileBNames[indexPath.row]];
        break;
    }

    case 2: {
        cell.textLabel.text = FileCNames[indexPath.row];
        cell.detailTextLabel.text = FileCDetails[FileCNames[indexPath.row]];
        break;
    }

default: break;
}

return cell;

不要像这样执行

返回操作。同时执行
中断操作
。谢谢！现在可以了。@Xcode初学者-没关系，请将其标记为已回答
switch (indexPath.section) {

    case 0:  {
        cell.textLabel.text = FileANames[indexPath.row];
        cell.detailTextLabel.text = FileADetails[FileANames[indexPath.row]];
        break;
    }

    case 1: {
        cell.textLabel.text = FileBNames[indexPath.row];
        cell.detailTextLabel.text = FileBDetails[FileBNames[indexPath.row]];
        break;
    }

    case 2: {
        cell.textLabel.text = FileCNames[indexPath.row];
        cell.detailTextLabel.text = FileCDetails[FileCNames[indexPath.row]];
        break;
    }

default: break;
}

return cell;
