解决方法
导出捆绑文档时,应将其压缩为ZIP文件.您可以使用与文档格式相同的扩展名保存ZIP文件,但显然这意味着您的应用程序需要同时处理文件类型的未压缩和压缩变体.我向Apple Developer Technical Support提出了类似的问题,他们回答了以下问题：
The Mail activity does not accept NSURLs pointing to bundles/packages. In order to share a package-type document,you must compress it into a zip archive. Pass either the URL of the archive or an NSData object containing the archive data as the activity item.
