Developing with the Extensibility Framework
The Extensibility Framework is an SDK for iOS applications, providing to developers the ability to add or replace screens or subviews, change navigation patters, update the data model, add custom actions, and so on. You can use it when developing new applications, but you can also extend existing applications with little effort; you need not recompile and redistribute the apps.
- Declarative structural extensibility define the UI layout, navigation patterns, data bindings, event handling, context passing, value formatting, undo behavior, and so on via configuration.
- Adaptive data management the framework is independent of the data model, because the data is abstracted. It provides a ready-to-use datasource adapter, which manages conversions between OData and the generic data format, but you can also implement custom data source adapters for other data formats.
- Integrated OData facade the SDMDataSource library is a wrapper that you can use on top of the SAP Mobile Platform Connectivity and OData management libraries. A set of simple APIs replace the usual coding required to manage network requests, parse and cache OData feeds, and to perform additional tasks that are related to online and offline OData handling.
- Customization points the framework exposes a set of protocols and delegates, so you can replace or decorate the default behavior based on your project’s needs. For example, you can implement delegates to create a view or a custom control, fix data validation issues, intercept actions fired by controls, modify the look and feel of UI elements, and so on.
- Support for Localizable Demo Data The framework provides support for localized demo data, which allows apps to start in offline mode, lets customers look at an app without requiring a connection.
- Skinnable UI elements (via MAF Reusable Components) the Mobile Application Framework (MAF) includes reusable components that fulfill the product standards of globalization, usability, and accessibility.
- Value, currency, date, time, and address formatting (via MAF Reusable Components) define the data to be formatted in the configuration XML to format and localize them based on different criteria, such as the device locale, the country code, or international prefixes for phone numbers.
- Advanced logging and error handling the framework includes meaningful log messages that precisely indicate the root cause of any problems, for example, by identifying any inappropriate values or parameters in the layout configuration XML file.
