Events

The Didomi SDK triggers various events to notify you that the user has taken some action (changed their consent status, open the preferences screen, etc.) or that an important event has happened.

This section describes what events are available and how to subscribe to them.

addEventListener

Add an event listener to catch events triggered by the SDK. Events listeners allow you to react to different events of interest. This function is safe to call before the ready event has been triggered.

Requires SDK to be initialized

No.

Parameters

Name	Type	Description
eventListener	EventListener	The event listener. An instance of a subclass of EventListener

Returns

Nothing

Example

Swift

let didomiEventListener = EventListener()

didomiEventListener.onConsentChanged = { event in
    // The consent status of the user has changed
}

didomiEventListener.onHideNotice = { event in
    // The notice is being hidden
}

didomiEventListener.onShowNotice = { event in
    // The notice is being shown
}

Didomi.shared.addEventListener(listener: didomiEventListener)

Objective-C

DDMEventListener *didomiEventListener = [[DDMEventListener alloc] init];

[didomiEventListener setOnConsentChanged:^(enum DDMEventType event) {
    // The consent status of the user has changed
}];

[didomiEventListener setOnHideNotice:^(enum DDMEventType event) {
    // The notice is being hidden
}];

[didomiEventListener setOnShowNotice:^(enum DDMEventType event) {
    // The notice is being shown
}];

[didomi addEventListenerWithListener:didomiEventListener];

Event types

This section presents a comprehensive list of the event types exposed by the Didomi SDK and usage examples.

onConsentChanged

Triggered when a consent is given or withdrawn by the user. It's only triggered when the consent status actually changes. For instance, if the user saves consents without adding/removing any consent then this does not get called.

Listener parameters

• event: EventType (enum)

Example

Swift

let didomiEventListener = EventListener()

didomiEventListener.onConsentChanged = { event in
    // The consent status of the user has changed
}
Didomi.shared.addEventListener(listener: didomiEventListener)

Objective-C

DDMEventListener *didomiEventListener = [[DDMEventListener alloc] init];
[didomiEventListener setOnConsentChanged:^(enum DDMEventType event) {
    // The consent status of the user has changed
}];
[didomi addEventListenerWithListener:didomiEventListener];

onHideNotice

Triggered when the consent notice is hidden. If you have disabled our default consent notice to replace it with your own, you need to hide your custom notice when this event gets triggered.

Listener parameters

• event: EventType (enum)

Example

Swift

let didomiEventListener = EventListener()

didomiEventListener.onHideNotice = { event in
    // The notice is being hidden
}
Didomi.shared.addEventListener(listener: didomiEventListener)

Objective-C

DDMEventListener *didomiEventListener = [[DDMEventListener alloc] init];
[didomiEventListener setOnHideNotice:^(enum DDMEventType event) {
    // The notice is being hidden
}];
[didomi addEventListenerWithListener:didomiEventListener];

onShowNotice

Triggered when the consent notice gets displayed. If you have disabled our default consent notices to replace them with your own, you need to show your custom notice when this event gets triggered.

Listener parameters

• event: EventType (enum)

Example

Swift

let didomiEventListener = EventListener()

didomiEventListener.onShowNotice = { event in
    // The notice is being shown
