您要执行的操作正是Core Text为您执行的操作.实际上，Core Text是如何 UITextView知道如何包装文本.因此，您可以询问Core Text，就像UITextView一样，换行符在哪里.请参阅我的答案中的示例代码-它比您尝试做的要简单得多且更可靠.

What you are asking to do is exactly what Core Text does for you. Indeed, Core Text is how UITextView knows how to wrap text. So you can ask Core Text where the line breaks are, just as UITextView does. See the example code in my answer - it's a lot simpler and more reliable than what you're trying to do.
