Face/Touch ID Question

Hi,

‘I currently have an app that uses face/Touch ID.


Currently, the user has to tap on a lock image to activate the sequence. I’ve noticed that other apps do not have this option, and I’d like to change my app to offer this.


Can anyone give me a hint on how to accomplish this?


Thanks,

Dan Uff

Please clarify what the other apps do to activate Face/Touch ID.


Also, keep in mind the iOS human interface guidelines:


Initiate authentication only in response to user action. An explicit action, like tapping a button, ensures that the user wants to authenticate. In the case of Face ID, it also increases the likelihood that the user is facing the camera.

I didnt See that, thanks for pointing that out.


ive noticed that some apps just log the user in without any user interaction at all (i.e. not having tap a button to activate touch/Face ID).

When a user opens the app it executes the code in the App Delegate's applicationWillEnterForeground: method or the didFinishLaunchingWithOptions: method. You can put your code there as if the user had tapped that "lock image".

Thanks.
