iOS SDK API reference
The complete API reference for the Knock iOS SDK.
In this section, you'll find the documentation for the classes and methods available in the iOS SDK.
Knock
#The top-level Knock class. This is a shared instance to interact with the SDK's API methods.
Knock.shared.setup()
#Sets up the shared Knock instance. Make sure to call this as soon as you can. Preferably in your AppDelegate.
Params
The public API key for the Knock environment.
The Knock APNs channel id that you plan to use within your app.
Optional startup options to configure your Knock instance.
KnockAppDelegate
#This class serves as an optional base class designed to streamline the integration of Knock into your application. By inheriting from KnockAppDelegate in your AppDelegate, you gain automatic handling of Push Notification registration and device token management, simplifying the initial setup process for Knock's functionalities.
The class also provides a set of open helper functions that are intended to facilitate the handling of different Push Notification events such as delivery in the foreground, taps, and dismissals. These helper methods offer a straightforward approach to customizing your app's response to notifications, ensuring that you can tailor the behavior to fit your specific needs.
Override any of the provided methods to achieve further customization, allowing you to control how your application processes and reacts to Push Notifications. Additionally, by leveraging this class, you ensure that your app adheres to best practices for managing device tokens and interacting with the notification system on iOS, enhancing the overall reliability and user experience of your app's notification features.
Key Features:
- Automatic registration for remote notifications, ensuring your app is promptly set up to receive and handle Push Notifications.
- Simplified device token management, with automatic storage of the device token, facilitating easier access and use in Push Notification payloads.
- Customizable notification handling through open helper functions, allowing for bespoke responses to notification events such as foreground delivery, user taps, and dismissal actions.
- Automatic message status updates, based on Push Notification interaction.
KnockInAppFeedViewModel
#KnockInAppFeedViewModel manages the state and behavior of the in-app feed. It handles data fetching, user actions, state updates, and feed configuration.
This class is used with our KnockInAppFeedView component, but it can also be used independently if you would like to build your own UI.
Properties
#Holds the current feed data.
Identifies the tenant associated with the current feed.
The currently active filter for displaying feed items.
Available filter options for customizing feed display.
Actions available at the top of the feed interface, such as archiving or marking all as read. If set to nil, this view will be hidden.
Configuration options for feed.
Publisher for feed item button tap events.
Publisher for feed item row tap events.
Methods
#Connects to the feed and subscribes to new message events.
Refreshes the feed using the original filter options.
Loads additional feed items when the end of the list is reached.
Determines if there are more pages of feed content that need to be fetched.
Archives a specific feed item.
Archives all items within the specified scope.
Marks all items in the feed as read.
Marks all unseen items as seen.
Marks message as interacted. Typically used when user taps on an item.
Called when a user performs a horizontal swipe action on a row item.
Called when a user taps on one of the action buttons at the top of the list.
Examples
#Authentication
#Knock.shared.isAuthenticated()
#Convenience method to determine if a user is currently authenticated for the Knock instance.
Returns: Bool
Params
Whether Knock should also check to make sure user has a user token. Only required when using a Knock prod environment.
Knock.shared.signIn()
#Sets the userId and userToken for the current Knock instance. If the device token and pushChannelId were set previously, this will also attempt to register the token to the user that is being signed in. This does not get the user from the database nor does it return the full User object. You should consider using this in areas where you update your local user's state.
Params
The Knock user ID to make requests against.
Example
Knock.shared.signOut()
#Sets the userId and userToken for the current Knock instance back to nil. If the device token and pushChannelId were set previously, this will also attempt to unregister the token to the user that is being signed out so they don't receive pushes they shouldn't get. You should call this when your user signs out
- Note: This will not clear the device token so that it can be accessed for the next user to login.
Example
User Management
#Knock.shared.getUserId()
#Fetch the userId that was set from the Knock.shared.signIn method.
Returns: String?
Knock.shared.getUser()
#Returns the current user's profile stored in Knock. https://docs.knock.app/api-reference/users/get
Returns: Knock.User
Knock.shared.updateUser()
#Updates the current user's profile in Knock. https://docs.knock.app/api-reference/users/get
Returns: Knock.User
Params
The User object that you want to set for the current user.
Channels/Push Notifications
#Knock.shared.getUserChannelData()

Knock.shared.updateUserChannelData()
#Updates the channel data for the current user on the channel specified with channelId.
Params
The channel ID to update the channel data for.
The data to update for the channel data.
Returns: Knock.ChannelData
Knock.shared.getApnsDeviceToken()
#Returns the apnsDeviceToken that was set from the Knock.shared.registerTokenForAPNS. If you use our KnockAppDelegate, the token registration will be handled for you automatically.
Returns String?
Knock.shared.registerTokenForAPNS()
#Registers an Apple Push Notification Service token so that the device can receive remote push notifications. This is a convenience method that internally gets the channel data and searches for the token. If it exists, then it's already registered and it returns. If the data does not exists or the token is missing from the array, it's added. If the new token differs from the last token that was used on the device, the old token will be unregistered.
You can learn more about APNs here.
