UIWebView in iOS app cannot see JavaScript when loaded through File Sharing

Question

In my iOS app, I have a way for the User to install a zip file through iTunes/Apps Tab/File sharing. The zip file contains HTML/CSS/JavaScript. The app unzips the file and index.html file is loaded in a UIWebView. This works fine.

I know when you add JavaScript files along with HTML/CSS files into the Resources folder in XCode, before compiling you need to move the JavaScript files from the Compile Resources folder into the Copy Bundle Resources folder or the HTML cannot find the JavaScript file.

For the resources that I am loading through iTunes File Sharing, it appears that the HTML files cannot find the JavaScript files. What else do I need to do when adding the files through File Sharing in order for the HTML to use the JavaScript file?

TIA, Linda

I would guess the baseURL parameter of whichever UIWebView load method you're using to display the HTML content is being set incorrectly. I would try setting baseURL to the file URL pointing to the folder containing the unzipped assets, perhaps using NSBundle's - (NSURL *)URLForResource:(NSString *)name withExtension:(NSString *)extension method, or something similar.
