# Survey Event Handlers

Run code just before a Luciq survey appears in your iOS app and again once it is dismissed, handy for pausing and resuming gameplay or video.

You can execute code in a handler that gets called before a survey is shown and after it has been dismissed. You can use this for things like pausing and resuming a game, for example.

### Before showing the survey

{% tabs %}
{% tab title="Swift" %}
{% code overflow="wrap" %}

```swift
Surveys.willShowSurveyHandler = {
    // Change some state
}
```

{% endcode %}
{% endtab %}

{% tab title="Objective-C" %}
{% code overflow="wrap" %}

```objectivec
LCQSurveys.willShowSurveyHandler = ^{
    // Change some state
};
```

{% endcode %}
{% endtab %}
{% endtabs %}

### After the survey has been dismissed

{% tabs %}
{% tab title="Swift" %}
{% code overflow="wrap" %}

```swift
Surveys.didFinishSurveyHandler = { (state, info, identifier) -> Void in
    // Code here
}
```

{% endcode %}
{% endtab %}

{% tab title="Objective-C" %}
{% code overflow="wrap" %}

```objectivec
LCQSurveys.didFinishSurveyHandler = ^(LCQSurveyFinishedState state, NSDictionary * _Nonnull info, NSString * _Nonnull identifier) {
    // Code here
};
```

{% endcode %}
{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.luciq.ai/ios/setup-luciq-for-ios/setup-in-app-surveys/survey-event-handlers.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
