AWS v2 SNS on iOS - createPlatformEndpoint: request

I have a push running when I set the endpoint in the SNS console. I now move on to creating an iOS app to create an endpoint. Then subscriptions.

The problem is that it BFTask *task = [sns createPlatformEndpoint:request];

returns, task.result is zero, not AWSSNSCreateEndpointResponse*

. BTW, task.error is also null.

From the .h file:

• @return An instance of BFTask. If successful, task.result will contain an instance of AWSSNSCreateEndpointResponse. If it fails, task.error may contain an NSError with domian AWSSNSErrorDomain and the following error code: AWSSNSErrorInvalidParameter, AWSSNSErrorInternalError, AWSSNSErrorAuthorizationError, AWSSNSErrorNotFound.

Amazon has not yet created examples for SNS in SDK v2. So I am also looking for someone who can have examples of creating endpoints and subscribing with SDK v2.

After starting the application, I call my method from:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [self awsStartWithDeviceToken:deviceToken];
} 

      

        
        
        
      

    

Code:

- (void)awsStartWithDeviceToken:(NSData *)deviceToken {

    // Get a hex string for the NSData deviceToken
    // http://stackoverflow.com/questions/7520615/how-to-convert-an-nsdata-into-an-nsstring-hex-string
    NSUInteger dataLength = [deviceToken length];
    NSMutableString *deviceTokenString = [NSMutableString stringWithCapacity:dataLength*2];
    const unsigned char *dataBytes = [deviceToken bytes];
    for (NSInteger idx = 0; idx < dataLength; ++idx) {
        [deviceTokenString appendFormat:@"%02x", dataBytes[idx]];
    }

    // Set the log level
    [AWSLogger defaultLogger].logLevel = AWSLogLevelVerbose;

    // Login
    AWSStaticCredentialsProvider *credentialsProvider = [AWSStaticCredentialsProvider credentialsWithAccessKey:AWS_ACCESSKEY secretKey:AWS_SECRETKEY];
    AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWS_REGION credentialsProvider:credentialsProvider];
    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

    // Create SNS Client
    //AWSSNS *sns = [[AWSSNS new] initWithConfiguration:configuration];
    AWSSNS *sns = [AWSSNS defaultSNS];

    // Create an Application Endpoint
    AWSSNSCreatePlatformEndpointInput *request = [AWSSNSCreatePlatformEndpointInput new];
    request.token = deviceTokenString;
    request.platformApplicationArn = AWS_APP_ARN;
    request.customUserData = [NSString stringWithFormat:@"Operation:%@ Alias:%@ Name:%@ Model:%@ (%@:%@)",
                            [self getOperation], [self getNotifyAlias], [UIDevice currentDevice].name, [UIDevice currentDevice].model,
                            [UIDevice currentDevice].systemName, [UIDevice currentDevice].systemVersion] ;
    BFTask *task = [sns createPlatformEndpoint:request];
}

      

        
        
        
      

    

Here's a description of the task:

• task.result = (id) 0.0
• task.error = (NSError *) nil

Here is the verbose log output:

No error returns, I'm at a loss what went wrong ... Ideas?

** Update to use async completion blocks **

    // Async call to create the platform endpoint
    [[[sns createPlatformEndpoint:request] continueWithSuccessBlock:^id(BFTask *task) {
        // success
        [self awsCreateTopicsAndSubscriptionsForEndpoint:task.result];
        return nil;
    }] continueWithBlock:^id(BFTask *task) {
        // failed
        if (task.error) {
            NSLog(@"Error: %@", task.error);
        }
        return nil;
    }];
}
