Basic HTTP Authentication on iPhone

Question

I\'m trying to get a small twitter client running and I ran into a problem when testing API calls that require authentication.

My password has special characters in

Two things. Firstly you have to use the async methods rather than the synchronous/class method.

NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:req]
                                                               cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                           timeoutInterval:30.0];

// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

The authentication is managed by implementing this method in your delegate:

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;

And you'll probably also need to implement these methods too:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data;
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error;
- (void)connectionDidFinishLoading:(NSURLConnection *)connection;

Using the async method tends to give a better user experience anyway so despite the extra complexity is worth doing even without the ability to do authentication.
