code to open .docx in iphone webView
===

I'm new in iPhone, I'm trying to open .docx file in UIwebView, I wrote the following code

    NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"Arabic literature" 
                                                                  ofType:@"docx"]; 
    NSURL *url  = [NSURL fileURLWithPath:urlAddress];
    NSURLRequest *requestObj  = [NSURLRequest requestWithURL:url];
    
    NSData *data = [NSData dataWithContentsOfFile:urlAddress];
    
    //[_webView loadRequest:requestObj];
    [_webView loadData:data MIMEType:@"application/vnd.ms-word" textEncodingName:@"UTF-8" baseURL:nil];

but it gives me the following exception:

    DiskImageCache: Could not resolve the absolute path of the old directory.
    Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'

consider that I copied the file "Arabic literature.docx" in Supporting files.
how can I solve this exception??
