Calling the function
Parameters
Type
Description
UIViewController
The controller you would like to present on.
An array of the questions (or actions) you would like the user to complete during active liveness; all questions are included if nil
is passed.
You have to send through the actions/questions as initialised objects. Use the code snippet below as a guide.
Then to add the actions when calling active liveness, you can simply pass it as a parameter on the function call, like so:
After executing liveness, the object inside the myQuestions
array will be modified and shouldn't be used for another liveness detection function call.
To reuse the same actions/questions for multiple liveness detections, you should initialise the array inline with the function call. Like so:
