ASIHTTPRequest UIWebView load documents - iphone

Question

What is the best way to view documents (pdf,doc,xls) using AsiHttpRequest and UIWebView??? I tried the following, but the UIWebView is displaying the html:
NSString * baseURL = #"http://xxxxxx/open-api/v1/";
NSString * itemRef = #"item/133/attachment/test.pdf";
NSString *urlString = [NSString stringWithFormat:#"%#%#", baseURL, itemRef];
NSURL *url = [NSURL URLWithString:urlString];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setUsername:#"xx"];
[request setPassword:#"xx"];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
[self.webView loadHTMLString:[request responseString] baseURL: [request url]];
}
else {
NSLog(#"Error: %#", error );
}
AsiHttpRequest is required for setting Basic Authentication and Header Values... Thanks!

Well, to be fair, you're telling it to display HTML, so the result isn't really unexpected :-)
You'd need to download the pdf file locally:
NSString *tmpLocation = // some temporary file location
[request setDownloadDestinationPath:tmpLocation]];
[request startSyncronous];
then view it in UIWebView:
NSURL *url = [NSURL fileURLWithPath:tmpLocation];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
