Release: AWS SDK for iOS 0.2.2

The awsBrowser (AWSiOSDemo) now contains demos for making Async requests. The code to make the Async request works the same for all services but only requests to S3 and SimpleDB are shown. Async requests require the use of a delegate that implements the AmazonServiceRequestDelegate protocol. In the sample application, the request delegates are named: S3RequestDelegate and SdbRequestDelegate.
The following samples show the creation and assignment of the delegate to a request object.

                S3RequestDelegate s3Delegate = [[S3RequestDelegate alloc] init];
            
                AmazonS3Client *s3 = [[AmazonS3Client alloc] initWithAccessKey:@"Access Key Here" withSecretKey:@"Secret Key Here"];
                S3CreateBucketRequest *cbr = [[[S3CreateBucketRequest alloc] initWithName:@"Your Bucket Name Here"] autorelease];
                [cbr setDelegate:s3Delegate];
                
                [s3 createBucket:cbr];  // Statement returns nil immediately.
             

                SdbRequestDelegate sdb = [[SdbRequestDelegate alloc] init];
                
                AmazonSimpleDBClient *sdbClient = [[AmazonSimpleDBClient alloc] init];
                SimpleDBSelectRequest *selectRequest = [[[SimpleDBSelectRequest alloc] initWithSelectExpression:selectExpression] autorelease];
                [selectRequest setDelegate:sdbDelegate]; 
                
                [sdb select:selectRequest]; // Statement returns nil immediately.
            

• didReceiveResponse: Sent when body data has been read. May be called multiple times.
• didReceiveData: Sent when body data has been read. May be called multiple times.
• didCompleteWithResponse: Sent when the entire response has been read and processed. The object sent to this method is the same object returned when making a non-asynchronous request.
• didSendData: Sent when the request transmitted data.
• didFailWithError: Sent when there was a basic failure with the underlying connection.
• didFailWithServiceException: Sent when the service responded with an error message.

• Bucket names can include '+' symbols in the name, but the '+' symbol does not get replaced in URL encodings and can result in spaces in bucket names instead.
• It is possible to create an object with a key which includes characters that are not valid XML characters, which will cause an error in the response to the AmazonS3Client listObjects method. Refer to http://docs.amazonwebservices.com/AmazonS3/2006-03-01/index.html?UsingKeys.html for guidelines on Amazon S3 keys.
