How to make UILabel text appear with "..." at the end when text is longer than label's width
提问by Polis
My issue is with a UILabel.
我的问题是一个UILabel.
The text it holds is much longer than the actual width of the UILabel. So I would like it to appear with "..." at the end to denote that there's more text.
它保存的文本比 UILabel 的实际宽度长得多。所以我希望它以“...”结尾，表示还有更多的文字。
I played around with horizontal content hugging priority (made it less than 251) but it doesn't seem to make a difference.
我玩过水平内容拥抱优先级（使其小于 251），但似乎没有什么区别。
Right now it just chops the text when the width fills up.
现在它只是在宽度填满时切割文本。
Any ideas?
有任何想法吗？

4) Check it by giving a text of more content size than label size.
4）通过提供比标签大小更大的内容大小的文本来检查它。
