推荐答案

如果您在NSAttributedString中使用HTML字符串，也可能会崩溃，如

If you working with HTML strings in NSAttributedString it also may crash, as it said in docs:

不应从后台线程调用HTML导入器( 是，选项字典包含NSDocumentTypeDocumentAttribute 的值为NSHTMLTextDocumentType).它将尝试同步 与主线程，失败，并超时.从主叫 线程有效(但如果HTML包含引用，仍可能超时 外部资源，应不惜一切代价避免).的HTML 导入机制旨在实现诸如markdown之类的东西 (即文本样式，颜色等)，而不适用于常规HTML 导入.

The HTML importer should not be called from a background thread (that is, the options dictionary includes NSDocumentTypeDocumentAttribute with a value of NSHTMLTextDocumentType). It will try to synchronize with the main thread, fail, and time out. Calling it from the main thread works (but can still time out if the HTML contains references to external resources, which should be avoided at all costs). The HTML import mechanism is meant for implementing something like markdown (that is, text styles, colors, and so on), not for general HTML import.

无论如何，您应该提供崩溃的更多详细信息，以获得正确的答案.

Anyway you should provide more details for your crash to get correct answer.
