  configuration

The service configuration used to instantiate this service client.

@property (nonatomic, strong, readonly) AWSServiceConfiguration *configuration

Discussion

Warning: Once the client is instantiated, do not modify the configuration object. It may cause unspecified behaviors.

Declared In

AWSLambdaService.h

+ defaultLambda

Returns the singleton service client. If the singleton object does not exist, the SDK instantiates the default service client with defaultServiceConfiguration from [AWSServiceManager defaultServiceManager]. The reference to this object is maintained by the SDK, and you do not need to retain it manually.

+ (instancetype)defaultLambda

Return Value

The default service client.

Discussion

For example, set the default service configuration in - application:didFinishLaunchingWithOptions:

Swift

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let credentialProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "YourIdentityPoolId")
    let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: credentialProvider)
    AWSServiceManager.default().defaultServiceConfiguration = configuration

    return true
}

Objective-C

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
      AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1
                                                                                                      identityPoolId:@"YourIdentityPoolId"];

– addPermission:

Adds a permission to the resource policy associated with the specified AWS Lambda function. You use resource policies to grant permissions to event sources that use push model. In a push model, event sources (such as Amazon S3 and custom applications) invoke your Lambda function. Each permission you add to the resource policy allows an event source, permission to invoke the Lambda function.

For information about the push model, see Lambda Functions.

If you are using versioning, the permissions you add are specific to the Lambda function version or alias you specify in the AddPermission request via the Qualifier parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:AddPermission action.

- (AWSTask<AWSLambdaAddPermissionResponse*> *)addPermission:(AWSLambdaAddPermissionRequest *)request

Parameters

request

A container for the necessary parameters to execute the AddPermission service method.

Return Value

An instance of AWSTask. On successful execution, task.result will contain an instance of AWSLambdaAddPermissionResponse. On failed execution, task.error may contain an NSError with AWSLambdaErrorDomain domain and the following error code: AWSLambdaErrorService, AWSLambdaErrorResourceNotFound, AWSLambdaErrorResourceConflict, AWSLambdaErrorInvalidParameterValue, AWSLambdaErrorPolicyLengthExceeded, AWSLambdaErrorTooManyRequests, AWSLambdaErrorPreconditionFailed.

– updateEventSourceMapping:completionHandler:

You can update an event source mapping. This is useful if you want to change the parameters of the existing mapping without losing your position in the stream. You can change which function will receive the stream records, but to change the stream itself, you must create a new mapping.

If you are using the versioning feature, you can update the event source mapping to map to a specific Lambda function version or alias as described in the FunctionName parameter. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

If you disable the event source mapping, AWS Lambda stops polling. If you enable again, it will resume polling from the time it had stopped polling, so you don't lose processing of any records. However, if you delete event source mapping and create it again, it will reset.

This operation requires permission for the lambda:UpdateEventSourceMapping action.

- (void)updateEventSourceMapping:(AWSLambdaUpdateEventSourceMappingRequest *)request completionHandler:(void ( ^ _Nullable ) ( AWSLambdaEventSourceMappingConfiguration *_Nullable response , NSError *_Nullable error ))completionHandler

Parameters

request

A container for the necessary parameters to execute the UpdateEventSourceMapping service method.

completionHandler

The completion handler to call when the load request is complete. response - A response object, or nil if the request failed. error - An error object that indicates why the request failed, or nil if the request was successful. On failed execution, error may contain an NSError with AWSLambdaErrorDomain domain and the following error code: AWSLambdaErrorService, AWSLambdaErrorResourceNotFound, AWSLambdaErrorInvalidParameterValue, AWSLambdaErrorTooManyRequests, AWSLambdaErrorResourceConflict, AWSLambdaErrorResourceInUse.

– updateFunctionCode:

Updates the code for the specified Lambda function. This operation must only be used on an existing Lambda function and cannot be used to update the function configuration.

If you are using the versioning feature, note this API will always update the $LATEST version of your Lambda function. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:UpdateFunctionCode action.

- (AWSTask<AWSLambdaFunctionConfiguration*> *)updateFunctionCode:(AWSLambdaUpdateFunctionCodeRequest *)request

Parameters

request

A container for the necessary parameters to execute the UpdateFunctionCode service method.

Return Value

An instance of AWSTask. On successful execution, task.result will contain an instance of AWSLambdaFunctionConfiguration. On failed execution, task.error may contain an NSError with AWSLambdaErrorDomain domain and the following error code: AWSLambdaErrorService, AWSLambdaErrorResourceNotFound, AWSLambdaErrorInvalidParameterValue, AWSLambdaErrorTooManyRequests, AWSLambdaErrorCodeStorageExceeded, AWSLambdaErrorPreconditionFailed.
