Why beforeInAppMessageDisplayed is never called?

Question

I want to use Braze to send in-app message notification and show customized UI to replace the UI created by Braze. But beforeInAppMessageDisplayed is never called. Below is how I done. I added

Appboy.start(withApiKey: apiKey, in: application, withLaunchOptions: launchOptions, withAppboyOptions: [ ABKInAppMessageControllerDelegateKey: self ]) in func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool

and also added

func beforeInAppMessageDisplayed(inAppMessage: ABKInAppMessage!) -> ABKInAppMessageDisplayChoice

in AppDelegate class.

Answer 1

我通过在funk beforeInAppMessageDisplayed（inAppMessage：ABKInAppMessage！）-> ABKInAppMessageControllerDelegate中的ABKInAppMessageDisplayChoice中解决了此问题。
