在Cocoa Touch中阅读.ppt（MS PowerPoint）文件 [英] Reading .ppt (MS PowerPoint) file in Cocoa Touch

问题描述

有什么想法如何读取Cocoa Touch中的.ppt文件？

Any idea how to read a .ppt file in Cocoa Touch ?

我试图在UIWebView中加载文件的内容，但是没有工作。
这是代码：

I tried to load the contents of the file in UIWebView but it didn't work. Here is the code :

[aWebView loadData:[NSData dataWithContentsOfFile:filePath]
          MIMEType:@"application/vnd.ms-powerpoint"
  textEncodingName:@"utf-8"
           baseURL:[NSURL fileURLWithPath:filePath]];

[powerWeb loadData:[NSData dataWithContentsOfFile:filePath]
          MIMEType:@"application/vnd.ms-powerpoint"
  textEncodingName:@"utf-8"
           baseURL:[NSURL fileURLWithPath:filePath]]; 

所有建议都非常感激。

感谢

推荐答案

UIWebView 用于以可以直接在浏览器中查看的格式显示Web内容。 它不知道如何显示PowerPoint文件 - 大多数应用程序不，因为它是一个专有的Microsoft格式。（我立即纠正 - 显然， UIWebView 确实知道如何显示PowerPoint文件和其他，如果它不工作，我建议尝试不同的MIME类型，例如 application / mspowerpoint 。）请记住，只需将文件加载到NSData中并不意味着任何其他人都可以传递该数据，从而知道如何解释字节。

UIWebView is for displaying web content, in a format you could view directly in a browser. It has no idea about how to display PowerPoint files — most applications don't, since it's a proprietary Microsoft format. (I stand corrected — apparently, UIWebView does know how to display PowerPoint files and others. If it's not working, I'd suggest trying a different MIME type, such as application/mspowerpoint.) Just remember that simply loading a file into an NSData doesn't mean that anyone else you pass that data to will know how to interpret the bytes.

您可以检查Microsoft是否提供了任何用于解析PPT文件的工具，或查看开源工具 - 例如，Google搜索经常转换为HTML。请注意，您的浏览器通常不会直接加载PowerPoint版本的文件。

You might check whether Microsoft offers any tools for parsing PPT files, or look around for open-source tools — for example, Google searches often convert to HTML. Just be aware that your browser is usually not loading a PowerPoint version of the file directly.
