自动换行是否需要自定义表视图单元格?如果不是，这是怎么做到的

Question

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
       UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MCell" forIndexPath:indexPath];
switch (indexPath.row) {
    case 0:
        cell.textLabel.text = @"My Policies";
        cell.textLabel.textColor = [UIColor redColor];
        ***cell.textLabel.numberOfLines = 0;***
        break;
    case 1:
        cell.textLabel.text = @"Payment Info";
        cell.textLabel.textColor = [UIColor redColor];
        break;
    case 2:
        cell.textLabel.text = @"Policy Notes";
        cell.textLabel.textColor = [UIColor redColor];
        break;
    case 3:
        cell.textLabel.text = @"Events";
        cell.textLabel.textColor = [UIColor redColor];
        break;
    default:
        cell.textLabel.text = @"Docs";
        cell.textLabel.textColor = [UIColor redColor];
        break;
}

      return cell;
}

Answer 1

不，没有必要，您可以通过将numberOfLines从 textLabel 设置为 0 来轻松换行，它会自动自动换行内容。

cell.textLabel.numberOfLines = 0;
