When is the app not open (background - kill app) - can I open pop up when Beacon was detected?
Your iOS app can show a notification, but it’s the user who decides how the notification will look—by default, it’s the banner that slides from the top, but there’s also an option for a popup.
According to this Stack Overflow question though, it’s not possible to set the style yourself—you can only ask the user to do it:
I think the banner is a much better UI pattern for the user, why would you want a popup instead?
Hi Can an app trigger popup screen when the device is in beacon vicinity and mobile device screen is unlocked?
