问题 I have an app that serves as custom lockscreen and I want to preserve unlock functionality using fingerprint. I want to unlock my phone when device screen is off or when I am looking at my lockscreen. The lockscreen is an activity that runs above all other components.

I'm new on Swift. I write because I want to ask a question. Me and my friend we are developing an audio player, but we have a problem.

问题 I have Activity1 which is a list screen of items. Each item can be viewed in a separate Activity2 which is displayed as a popup. Activity1 can be launched from the background and displayed even when the screen is locked. Activity1 may also choose to automatically display the contents of an item in the list screen by starting Activity2 .
