How to make text in a UITableViewCell wordwrap?
提问by Sheehan Alam
I have a grouped UITableView with a few sections. The text in some of the cells can get quite long, I was wondering how I could make the text word-wrap?
我有一个包含几个部分的分组 UITableView。某些单元格中的文本可能会很长，我想知道如何使文本自动换行？

eg
例如
textLabel.numberOfLines = 0;
You can set this to a fixed number of lines if you prefer. It may be a good idea to set the lineBreakMode, and you will probably need to implement:
如果您愿意，可以将其设置为固定的行数。设置 lineBreakMode 可能是个好主意，您可能需要实现：
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
using:
使用：
NSString sizeWithFont:constrainedToSize:

You'll have the specify the number of lines the text will use. Setting it to zero will wrap it automatically.
您将指定文本将使用的行数。将其设置为零将自动包装它。
cell.textLabel.numberOfLines=0; // line wrap

set numberOfLines > 1 on your label and set an appropriate lineBreakMode as well. You might need to modify the frame of the label to have enough space. You can do this in tableView:willDisplayCell:forRowAtIndexPath: of your table view delegate.
在标签上设置 numberOfLines > 1 并设置适当的 lineBreakMode。您可能需要修改标签的框架以获得足够的空间。您可以在 tableView:willDisplayCell:forRowAtIndexPath: 的表格视图委托中执行此操作。

It looks like this question Custom Cell Height, right? I don't really get what word-wrap do, but I assume that you want to change the cell size according to the text length, is that right? So you can look at the above question and answer
看起来像这个问题Custom Cell Height，对吧？我真的不明白自动换行的作用，但我假设您想根据文本长度更改单元格大小，对吗？所以你可以看看上面的问答
