Two pieces of software related to previewing iOS specific format files are QuickLook and Combine PDF pages in Automator action/contacts/Resources/join. py script, which is self-contained with a rich tool library in the apple iOS system. The QuickLook tool and the scripts described above can be used to preview various types of files such as photos and other pictures, plain text, rich text, PDF files, Microsoft Office documents, web Pages, and Pages, Keynote, Number of iOS systems. However, the precondition is that the preview of the iOS specific format file is required to be completed under the iOS operating system, and thus the requirement for previewing the iOS specific format file under the non-iOS system cannot be met.

In addition, web browser, WeChat, and like applications have been well supported in a variety of operating systems, including iOS, while viewing PDF formatted files. For example, a local PDF file may be opened directly with a web browser, WeChat, or the like application software to preview the content therein. However, these applications are not supported for iOS specific format files such as Pages, Keynote, Number, etc.

Based on the situation, the invention provides a technology for conveniently and quickly previewing files in the specific iOS format on the non-iOS system, namely, the script service mentioned above is called on the non-iOS system, so that the files in the specific iOS format can be previewed in multiple platforms, and the embarrassment that the files in the specific iOS format cannot be opened on operating system computers such as Windows and Linux is solved. After the user newly uploads the iOS specific format files such as Pages, Keynote, Number and the like, the invention converts the iOS specific format files into PDF files by utilizing the technology and makes cache, thereby avoiding repeated conversion of the same files. When the user wants to preview these iOS specific format files, the system directly transmits the corresponding address of the converted PDF file to the corresponding front-end application software, thereby achieving the purpose of previewing iOS specific format files such as Pages, Keynote, Number, and the like.
