Summary:
iOS 9 added a number of APIs to allow 3rd party (non-Apple) apps to accept text input from the user as response to a notification (see API header below).

ANCS is currently only capable of delivering notifications to the user. It can also take one, predefined action on them ("Clear"). Now that iOS 9 allows apps to accept textual responses, it's time for ANCS to take the next step as well and provide a way for users to input a textual response into an ANCS-enabled accessory and have ANCS relay it to the right app.

The relevant, newly added iOS 9.0 beta 1 APIs:

UIUserNotificationActionBehavior (from UIUserNotificationSettings.h)

typedef NS_ENUM(NSUInteger, UIUserNotificationActionBehavior) {
    UIUserNotificationActionBehaviorDefault,        // the default action behavior
    UIUserNotificationActionBehaviorTextInput       // system provided action behavior, allows text input from the user
} NS_ENUM_AVAILABLE_IOS(9_0);


UIKIT_EXTERN NSString *const UIUserNotificationTextInputActionButtonTitleKey NS_AVAILABLE_IOS(9_0);
UIKIT_EXTERN NSString *const UIUserNotificationActionResponseTypedTextKey NS_AVAILABLE_IOS(9_0);

// The behavior of this action when the user activates it.
@property (nonatomic, assign, readonly) UIUserNotificationActionBehavior behavior NS_AVAILABLE_IOS(9_0);
// Parameters that can be used by some types of actions.
@property (nonatomic, copy, readonly) NSDictionary *parameters NS_AVAILABLE_IOS(9_0);


And from UIApplication.h:

- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void(^)())completionHandler NS_AVAILABLE_IOS(9_0);
- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forLocalNotification:(UILocalNotification *)notification withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void(^)())completionHandler NS_AVAILABLE_IOS(9_0);
