WARN: WARNING ITMS-90737: "Invalid Document Configuration.
Document Based Apps should support either the Document Browser (UISupportsDocumentBrowser = YES) or implement Open In Place (LSSupportsOpeningDocumentsInPlace = YES/NO).
Visit https://developer.apple.com/document-based-apps/ for more information."
如果你的app中有用到UIDocumentInteractionController来打开文件，需要在info.plist中设置UISupportsDocumentBrowser为YES
