iOS 8中的UITextView崩溃，属性字符串包含表

在iOS 8中（甚至可能在iOS 7/7.1中），iOS上的NSAttributedString添加了呈现文本表的功能。此API不在iOS上，但不在iOS上。但是，通过将包含表的HTML传递给用户，可以在iOS上创建包含文本表的属性字符串

属性字符串已正确创建，但当我尝试使用

UITextView

呈现字符串时，会引发此异常：

<NSATSTypesetter: 0x7f8900faec90>: Exception *** -[NSConcreteTextStorage attribute:atIndex:effectiveRange:]: Range or index out of bounds raised during typesetting layout manager <NSLayoutManager: 0x7f8902e13440>

我认为这是苹果方面的一个错误，并试图创建一个最小的项目来重现这个问题，但无法做到。在我的测试项目中呈现完全相同的属性字符串效果很好，但在我的应用程序中仍然不起作用，这让我相信可能我做错了什么。在没有表的情况下呈现属性化字符串效果很好，这是一个特定于呈现表的问题。还有其他人遇到过类似的问题吗
