AUTHENTICATE YOUR PLAYER: AMAZON COGNITO

//Create and configure Cognito credentials provider

AWSCognitoCredentialsProvider *credentialsP = [AWSCognitoCredentialsProvidercredentialsWithRegionType:AWSRegionUSEast1 accountId:@"0123456789” identityPoolId:@”us-east-1:beeeeeef-beef-beef-beef-beef” unauthRoleArn:@"arn:aws:iam::0123456789:role/Unauth” authRoleArn:@"arn:aws:iam::0123456789:role/Auth"];

//Set Cognito as default credentials provider for all AWS service calls

AWSServiceConfiguration *configuration = [AWSServiceConfigurationconfigurationWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsP];

[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
