Xcode path resources in Cordova structure - objective-c

Question

how can I change in Xcode this line
NSString *filePath = [[NSBundle mainBundle] pathForResource:(#"%#",[command.arguments objectAtIndex:0]) ofType:#"pdf"];
to look in Phonegap (cordova) file structure for the PDF like:
~/Library/Caches
or
~/Docuemnts

I don't have a definite answer for you, but I believe the cordova-plugin-file plugin is where the answer will be found. I have only limited experience with it, but it looks like you would be looking for the following paths:
cordova.file.cacheDirectory = '~/Library/Caches'
cordova.file.documentsDirectory = '~/Documents'
From the cordova documentation, it looks like you'll be trying to get a DirectoryEntry from the window object, and then use a DirectoryReader to iterate over the contained files. There may be a search, but I don't know the API well enough beyond the basics.
var bundleDocs = window.resolveLocalFileSystemURL(cordova.file.documentsDirectory);
var bundleDocsReader = bundleDocs.createReader();
bundleDocsReader.readEntries(
function success(files) { // iterate over files and do stuff },
function error(err) { // respond to error }
);
Hope that helps!
NOTE: The direct API references for DirectoryEntry and DirectoryReader link to the Cordova 3.0 documentation because the Cordova 5.1 documentation for plugins is awful.
