How to use Face State Triggers in iOS

Banuba SDK has several face state triggers. To use them, you need to follow the next steps

Usage of Face State Triggers in your iOS app

1. Import BanubaEffectPlayer framework into your project.
   import BanubaEffectPlayer
2. Add BNBFrameDataListener to your ViewController
   sdkManager.effectPlayer?.add(self as BNBFrameDataListener)

   note

   Remove BNBFrameDataListener when your ViewController is deinited

   sdkManager.effectPlayer?.remove(self as BNBFrameDataListener)
3. Inherit interface BNBFrameDataListener and add protocol stubs
   extension ViewController: BNBFrameDataListener {

   func onFrameDataProcessed(_ frameData: BNBFrameData?) {

   }

   }
4. From BNBFrameData you can get information about smile, mouth, brows and others
   extension ViewController: BNBFrameDataListener {

   func onFrameDataProcessed(_ frameData: BNBFrameData?) {

   guard let fD = frameData else { return }

   fD.getIsMouthOpen() //-> Bool

   fD.getIsSmile() //-> Bool

   fD.getIsBrowsRaised() //-> Bool

   fD.getIsBrowsShifted() //-> Bool

   }

   }
5. Now you can use Face State Triggers in your iOS app
