    copied!<p>I'm trying to get a small twitter client running and I ran into a problem when testing API calls that require authentication.</p> <p>My password has special characters in it, so when I try to use the following code it doesn't work.</p> <pre><code>NSString *post = [NSString stringWithFormat:@"status=%@", [status stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@:%@@%@/statuses/update.json", username, password, TwitterHostname]]; [request setURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLResponse *response; NSError *error; [NSURLConnection sendSynchronousRequest:request returningResponse:&amp;response error:&amp;error]; </code></pre> <p>I started looking into base64 and putting the authentication into the headers. I found <a href="http://www.dribin.org/dave/blog/archives/2006/03/12/base64_cocoa/" rel="noreferrer">Dave Dribin's</a> post on his base64 implementation, and it seemed to make sense. However when I tried to use it the compiler started complaining about how it couldn't find the openssl libraries. So I read that I needed to link in the libcrypto library, but it doesn't seem to exist for iphone.</p> <p>I've also read people saying that apple won't allow apps that use crypto libraries, which doesn't make sense to me.</p> <p>So now I'm kinda stuck and confused. What's the easiest way to get basic authentication into my app?</p> <p>Cheers</p>
