TouchID calls applicationWillResignActive and applicationDidBecomeActive

Question

I am wondering if this is intended by Apple that these lifecycle methods are called upon using TouchID functionality.

Is there any possibility to check if the touchID pr

You can create a static bool in your login script that you can check from your AppDelegate!

static var isShowingTouchID = false

Then before your context.evaluatePolicy call, you can set it to true, and in the callback function, set it to false. I believe you use the reply argument to set a callback to this.

Then in your AppDelegate, check the status of this bool.

Originally I was using a public variable in AppDelegate and setting that, but I feel similarly in that I didn't want to do that. Frankly, I don't like this solution either, but it was the only one I could come up.

I even tried overriding viewDidDisappear in my login script, but I quickly found out that it was not being called even when I tapped "Cancel" on the touch ID prompt.

If anyone has a better solution, I would love to know.
