How to write multiple lines in a label
提问by Lea Cohen
I have a XIB file of type View XIB. In it I have a View controller, and in the View controller I have a label.
I have long text that I want to break, but it doesn't - it gets truncated.
I tried this solution- I did it in the attribute window - but it doesn't help.
我有一个查看 XIB 类型的 XIB 文件。在其中我有一个视图控制器，在视图控制器中我有一个标签。
我有很长的文本想要打破，但它没有 - 它被截断了。
我尝试了这个解决方案- 我在属性窗口中做到了 - 但它没有帮助。

You could use a TextView and disable the Editableand User Interaction Enabledoptions in IB.
您可以使用 TextView 并禁用IB 中的Editable和User Interaction Enabled选项。

use this
用这个
myLabel.lineBreakMode = UILineBreakModeWordWrap;
if you are worried about backwards compatibility use this because the comand i mentioned before was introduced in iOS 6.0
如果您担心向后兼容性，请使用它，因为我之前提到的命令是在 iOS 6.0 中引入的
myLabel.numberOfLines = 0;

I have been running into a similar problem. I started out with a label, but wanted multi-lines and a UITextViewworked great for this, at first. Because I am using a third party library (MBProgressHUD) to handle stuff like progress messages and what not, I had thread problems when trying to update a UITextViewand show the progress message at the same time.
我遇到了类似的问题。我从一个标签开始，但UITextView起初想要多行并且非常适合这个。因为我使用第三方库 ( MBProgressHUD) 来处理诸如进度消息之类的东西，所以我在尝试更新 aUITextView并同时显示进度消息时遇到了线程问题。
So I went back to UILabelwhich actually didn't have thread problems. I found a property to allow a specific number of lines of my choosing, and had to create the label big enough to display those lines. The downfall to this approach is that I don't get the context menus like Copy, Paste, etc. but more importantly I'm not running into thread problems. I can always embed this into a UIScrollViewin the future if I so choose.
所以我回到UILabel实际上没有线程问题的地方。我找到了一个属性来允许我选择特定数量的行，并且必须创建足够大的标签来显示这些行。这种方法的缺点是我没有得到像复制、粘贴等这样的上下文菜单，但更重要的是我没有遇到线程问题。UIScrollView如果我愿意，我可以随时将其嵌入到 a中。

You could check out my category for UILabel on GitHub. https://gist.github.com/1005520

This lets you resize the height of the label to accommodate the content.
这使您可以调整标签的高度以适应内容。

From the Attiribute inspector, choose LineBreaks->Word Wrap option when you have selected the lablel. Also increase the number of lines Label->Lines.
选择标签后，从属性检查器中选择 LineBreaks->Word Wrap 选项。还要增加 Label->Lines 的行数。
