# iOS

### iOS Info.plist

Add these lines to the Info.plist file in you iOS module:

```plist
<key>NSCameraUsageDescription</key>
<string>Camera Permission</string>
<key>NSMotionUsageDescription</key>
<string>Motion Permission</string>
```

### iOS WebView (Swift)

In order for web Onboarding integrations that use WKWebView for iOS to function properly, it is necessary to customize the configuration to allow media playback without request user's action and to reproduce the media inline.

{% hint style="warning" %}
For iOS, **WKWebView** is the preferred WebView. The example below is a basic illustration.
{% endhint %}

#### AppDelegate

```swift
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = WebViewController()
        window?.makeKeyAndVisible()
        return true
    }
}
```

#### SceneDelegate

```swift
import UIKit

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let windowScene = scene as? UIWindowScene else { return }

        window = UIWindow(windowScene: windowScene)
        window?.rootViewController = WebViewController()
        window?.makeKeyAndVisible()
    }
}
```

#### WebViewController

```swift
@preconcurrency import WebKit
import AVFoundation

class WebViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupViews()
        setupConstraints()
    }

    func setupViews() {
        let webConfiguration = WKWebViewConfiguration()
        webConfiguration.allowsInlineMediaPlayback = true
        webConfiguration.defaultWebpagePreferences.allowsContentJavaScript = true
        webConfiguration.mediaTypesRequiringUserActionForPlayback = []

        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.navigationDelegate = self
        webView.uiDelegate = self
        view.addSubview(webView)

        let request = URLRequest(url: URL(string: "https://cadastro.io/:token")!)
        webView.load(request)
        
        AVCaptureDevice.requestAccess(for: .video) { granted in
            if granted {
                // Access granted
            } else {
                // Access denied
            }
        }
    }

    func setupConstraints() {
        webView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            webView.topAnchor.constraint(equalTo: view.topAnchor),
            webView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            webView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            webView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
        ])
    }
}
```

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.caf.io/caf-docs/quick-start-guides/onboardings-integration/webview/webview_ios.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
