iOS Webview API References

We use webView to communicate with the SDK. If you need any help to understand how we get webView or to check how to setup WebView and to initialize properly check the Setup Page.

iOS Webview Method

All communication is achieved by sending post messages using the webView

var payload = payloadData
payload["type"] = type
if let jsonData = try? JSONSerialization.data(withJSONObject: payload),
    let jsonString = String(data: jsonData, encoding: .utf8) {
    let script = "window.postMessage(\(jsonString), '*');"
    webView.evaluateJavaScript(script, completionHandler: nil)
}

We just send different payloads and types for different functionalities.

Payloads

To get started, we send the type asinitialize type and payload with the desired settings. This adds the GlamAR SDK into the target container and configures it with the provided API key and optional configuration we sent through the payload.

let type = "initialize"
let payload: [String: Any] = [
  "type": type,
  "payload": [
    "apiKey": "YOUR_ACCESS_KEY",
    "platform": "ios",
  ]
]
if let jsonData = try? JSONSerialization.data(withJSONObject: payload),
   let jsonString = String(data: jsonData, encoding: .utf8) {
   let script = "window.postMessage(\(jsonString), '*');"
   webView.evaluateJavaScript(script, completionHandler: nil)
}
