+
+UIExtensionContentSession是[UIExtensionAbility](js-apis-app-ability-uiExtensionAbility.md)加载界面内容时创建的实例对象，当UIExtensionComponent控件拉起指定的UIExtensionAbility时，UIExtensionAbility会创建UIExtensionContentSession对象，并通过[onSessionCreate](js-apis-app-ability-uiExtensionAbility.md#uiextensionabilityonsessioncreate)回调传递给开发者。一个UIExtensionComponent控件对应一个UIExtensionContentSession对象，提供界面加载，结果通知等方法。每个UIExtensionAbility的UIExtensionContentSession之间互不影响，可以各自进行操作。
