Release: AWS SDK for iOS 1.3.2

Signature Version 4 will enable AWS to support future growth and evolution of the AWS business. This release of the AWS SDK for iOS uses Signature Version 4 for the Auto Scaling, Amazon CloudWatch and Amazon DynamoDB.

For more information about AWS Signature Version 4, go to Signature Version 4 Signing Process in the AWS Documentation.

Now you can set an Amazon SNS topic for bounce or complaint notifications by verified domain or email address and receive them in a simple JSON format. This release of the AWS SDK for iOS supports the Bounce and Complaint Notifications for the Amazon Simple Email Service.

For more information about Bounce and Complaint Notifications, go to Bounce and Complaint Notifications in the AWS Documentation.

The Token Vending Machine sample client has better error handling logic.

While the rest of the AWS SDK for iOS still support iOS versions 4.1 and later, the AWS Core Data Persistence Framework only supports iOS versions 5.0 and later.

There is a known issue with the AmazonLogger in "verbose mode" in iOS5.1 with release builds (AdHoc/AppStore distributions). The latest version of AWS SDK for iOS has a fix and we recommend including the following code segment to prevent your app from crashing:

            #ifdef DEBUG
                [AmazonLogger verboseLogging];
            #else
                [AmazonLogger turnLoggingOff];
            #endif
        

Uploading large objects to Amazon S3 using 3G can fail frequently. Upgrading your iOS device to v4.3 helps reduce the failure rate. We are actively working with Apple to find a resolution to this problem.

Users may also refer to the following Article as a work around to uploading larger files over 3G.

• 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.
