UIWebView does not open ms word (doc) and ms excel (xls) files

I am developing an application for iPad using Xcode 3.2.5 iOS SDK 4.2. For this application, you need to open PDF, DOC and XLS files and view them to the user.

I am trying to open them using a UIWebView control. Only PDF files open. When opening a DOC or XLS, I got a black blank view. This happens in Simulator and Device.

What am I doing wrong?

Here is the code:

-(void)prepareToShow:(NSString*)filePath fileType:(NSString*)fileType request:(NSURLRequest*)request{

UIWebView *webView = (UIWebView*)self.view;
self.actualFilePath = filePath;

NSLog(@"File Path %@",filePath);

NSString *mimeType = @"";
if ([fileType caseInsensitiveCompare:@"PDF"]==NSOrderedSame){
    mimeType = @"application/pdf";
} else  if ([fileType caseInsensitiveCompare:@"DOC"]==NSOrderedSame){
    mimeType = @"application/msword";
} else  if ([fileType caseInsensitiveCompare:@"XLS"]==NSOrderedSame){
    mimeType = @"application/vnd.ms-excel";
}

[webView loadData:[NSData dataWithContentsOfFile:filePath] MIMEType:mimeType textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@"http://www.google.com"]];

}

To download words or Excel or PDF documents you need physical path document file. this means that the file should saved in document or temporary directoryor may be in application bundle.

//now use file path to load in webview
[yourWebView loadRequest:[NSURLRequest requestWithURL:[NSURL  fileURLWithPath:yourFilePath]]];
