OData SDK Components and APIs

The iOS OData SDK provides the means to easily build an app which relies on the OData protocol and the additions made by SAP.

OData SDK - iOS

The following figure shows the main components of the OData SDK on iOS.

The iOS version of the OData SDK is presented as static libraries and header files. (Custom dynamic libraries are not allowed on iOS.)

The OData SDK for iOS includes a set of core iOS libraries acting independently from each other. Each core library has well-defined responsibilities and provides APIs for OData parsing, caching, persistence, keychain, certificate management, and so on.

The full list of APIs and their descriptions are available after the installation of Sybase Unwired Platform at the following location within your installation folder:SUP_HOME MobileSDK22\OData\iOS\docs

The libraries are provided in binary form as .a files, along with the public headers containing the APIs and the input/output structures. As a prerequisite, the public headers and the libraries must be available as separate binaries for release and debug, or merged using the lipo tool.

• SDMParser
  The SDMParser library provides APIs to convert OData XML payloads to native Objective-C objects and structures (arrays, dictionaries).
• SDMCache
  The SDMCache is a programming interface that provides in-memory cache for quick data access. Its APIs allow adding, removing and searching items stored in the cache. The cache also acts as a central, shared storage, avoiding the need to pass frequently used data between view controllers.
• SDMPersistence
  The SDMPersistence library provides APIs to persist data to the device's physical storage.
• SDMConnectivity
  The Connectivity library exposes APIs required to set up and start HTTP requests, and retrieve the payloads. For crossing a company firewall for enterprise use cases, you need to use Sybase Unwired Platform. Therefore, the connectivity component in the OData SDK offers a connection to Sybase Unwired Platform by default. For development and demo purposes, the SDK also provides a possibility to use HTTP or HTTPS.
• SDMSupportability
  The SDMSupportability library provides functionality for logging, tracing and performance measurement.
