iphone - List saved files in iOS documents directory in a UITableView?

I have set up the following code to save a file to the documents directory:

NSLog(@"Saving File...");

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reddexuk.com/logo.png"]];
AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:request] autorelease];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"logo.png"];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Successfully downloaded file to %@", path);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

[operation start];

However, I wish to add each file to a UITableView when it is successfully saved. When the file in the UITableView is tapped, I'd like a UIWebView to navigate to that file (all offline).

Also - how can I just get the filename and ending such as "logo.png" instead of http://www.reddexuk.com/logo.png?

How can I do this?

Here is the method I use to get the content of a directory.

-(NSArray *)listFileAtPath:(NSString *)path
{
    //-----> LIST ALL FILES <-----//
    NSLog(@"LISTING ALL FILES FOUND");

    int count;

    NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:NULL];
    for (count = 0; count < (int)[directoryContent count]; count++)
    {
        NSLog(@"File %d: %@", (count + 1), [directoryContent objectAtIndex:count]);
    }
    return directoryContent;
}
