Loading pdf file from iPhone Documents folder into a UIWebView

Question

I'm currently trying to include the ability for my App to download a "pdf" file from the web,... display the image in a UIWebView,.. save it to the iPhone,... and later redisplay it in the same UIWebView while "off line". I've been able to do everything but get the web view to load/display the stored pdf file. The App finds the .pdf file...
Here's the path it finds in the Simulator...
Image File Path: /Users/FCR/Library/Application Support/iPhone Simulator/User/Applications/8E29ACDF-4A56-4AC2-BFA0-C4F8E00E1481/Documents/AD_K EWR.pdf
... but I'm not much into html and can't seem to come up with a url scheme to load the image. I've tried several attempts using the URL... "file:///" ... but so far haven't been able to get the file (which is in the iPhone's Documents folder) to display. I seem to be about one line short of a workable solution.
Can anyone offer a bit of code (help) to accomplish this seemingly easy task of displaying it in the UIWebView?... It would be much appreciated!

Can you please post the code snippet used to download and save the PDF to the iPhone? I did not know you could do that.

Ed,... Here's the code ... I've cut and pasted from a couple different routines, but you should get the point...

- (BOOL)downloadPDF:(NSString *)pdfFileName
// Download a (pdf) file
BOOL success = NO;
NSString *urlStr = \[NSString stringWithFormat:@"http://... web path to file .../%@", pdfFileName\];
if(urlStr)
NSURL *PDF_URL = \[NSURL URLWithString:urlStr\];
NSMutableData *receivedData = \[NSData dataWithContentsOfURL: PDF_URL\];
if(receivedData)
success = YES;
NSLog(@"PDF downloaded... Save it to file: %@",pdfFileName);
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
if (paths.count > 0)
NSString *documentsDirectory = \[paths objectAtIndex:0\];
NSString *filePath = \[documentsDirectory stringByAppendingPathComponent: pdfFileName\];
if(\[receivedData writeToFile:filePath atomically:YES\])
success = YES;
NSLog(@"Saved file: %@",filePath);
else
NSLog(@"Failed to save PDF to: %@",filePath);
return success;
}
