ios - NSAttributedString EXC_BAD_ACCESS KERN_INVALID_ADDRESS 崩溃

Question

我在我的代码中使用了 NSAttributedString。我有时会遇到以下崩溃。

Crashed: com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000000114f2841 Raw 0 libobjc.A.dylib
objc_msgSend + 5 15 UIFoundation
-[NSAttributedString(NSAttributedStringUIFoundationAdditions) initWithData:options:documentAttributes:error:] + 116

有人可以帮我解决这个问题吗？。提前致谢。

如果您在 NSAttributedString 中使用 HTML 字符串，它也可能会崩溃，如 docs 中所述:

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，您应该提供有关崩溃的更多详细信息以获得正确答案。
