Answer 1

Try using a QuickLook Framework which is an amazing feature given by Apple. If you have seen this that when you select ANY FILE on MAC System and click SPACE BAR then you will a quick preview of your file it may be any thing... *.pdf, *.doc, *.docx or any thing... Even if you have not installed those softwares for same files you will get a PREVIEW for those files...

QuickLook framework also gives same functionality... Please go through some of the links for the same..

Answer 2

You need to supply something to baseURL:. For example:

[webView loadData:requestData MIMEType:@"application/msword" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@"http://localhost/"]];

Works for me now.

Answer 3

Not all of those formats (docx) are supported. This looks like the official word. In the example Apple does not specify a mime type.

This question suggests that you must use an NSURLRequest instead of loadData.

Edit:

As far as I have seen, you cannot directly pass data to loadData for these types.

The easy work around is to write to a temporary file. You can delete it in webViewDidFinishLoad or, technically, as soon as the the file has been opened.

The hard work around is to use NSURLCache. You should be able to implement a custom NSURLCache and have WebKit use it via setSharedURLCache. Your cache would basically know how to get your local encrypted files and pretend that they are cached. I have not tried this, but I think it is your best bet. This approach may be blocked just like loadData is.

Answer 4

Try it on an iPhone instead of Simulator
