UIDocumentInteractionController-读取文档时出错 [英] UIDocumentInteractionController - Error while reading the document
问题描述
我使用UIDocumentInteractionController在应用程序中预览文档。但是,有时文档显示得很好,而其他时候,交互控制器会显示一条消息读取文档时出错。我知道这与文档无关,因为同一文档有时会显示,有时却不会。
I preview docs in my app using a UIDocumentInteractionController. However, sometimes documents show fine, other times the interactioncontroller displays a message "Error while reading the document". I know it is not an issue with the document, because the same document sometimes shows and sometimes doesn't.
重新启动设备可以暂时解决此问题-因此,这似乎是内存问题,但奇怪的是我没有收到任何内存警告。请问如何使它可靠地工作的任何想法?
Restarting the device solves this problem temporarily - so it would appear to be a memory issue, but strangely I am not getting any memory warnings. Any ideas on how to get this to work reliably please?
注意:
- 文档交互控制器预览被关闭,
控制器在完成时释放,以确保不会在内存中保留先前的预览 - 我在使用quicklook控制器时遇到了相同的问题
推荐答案
经过大量测试,看来此问题仅限于iPad1。唯一的解决方法是重新启动。
After much testing it appears this issue is limited to iPad 1. The only workaround is a restart.
