IOS---Extension Programming Guide

When iOS 8.0 and OS X v10.10 were released, a whole new concept came to our eyes: Application extensions. As the name implies, app extensions allow developers to extend the app's custom features and content, allowing them to use the feature when using other apps. You can develop an application extension to perform certain tasks that users can perform in multiple contexts after they use the extension. For example, you provide an extension that allows users to share content to a social networking site, and users can post comments via app extensions when they are reading email messages or surfing the web. Or, if you provide an extension that shows the current score, then the user can put it in the notification center so that they can see the latest score when they open the Today view. You can even develop an extension that provides a custom keyboard that users can use instead of the keyboard that comes with the iOS system.
