I am trying to implement "Live activity" to my app. I am following the Apple docs.
Link: https://developer.apple.com/documentation/activitykit/displaying-live-data-with-live-activities
Example code:
struct LockScreenLiveActivityView: View {
let context: ActivityViewContext<PizzaDeliveryAttributes>
var body: some View {
VStack {
Spacer()
Text("\(context.state.driverName) is on their way with your pizza!")
Spacer()
HStack {
Spacer()
Label {
Text("\(context.attributes.numberOfPizzas) Pizzas")
} icon: {
Image(systemName: "bag")
.foregroundColor(.indigo)
}
.font(.title2)
Spacer()
Label {
Text(timerInterval: context.state.deliveryTimer, countsDown: true)
.multilineTextAlignment(.center)
.frame(width: 50)
.monospacedDigit()
} icon: {
Image(systemName: "timer")
.foregroundColor(.indigo)
}
.font(.title2)
Spacer()
}
Spacer()
}
.activitySystemActionForegroundColor(.indigo)
.activityBackgroundTint(.cyan)
}
}
Actually, the code is pretty straightforward. We can use the timerInterval for count-down animation. But when the timer ends, I want to update the Live Activity view. If the user re-opens the app, I can update it, but what happens if the user doesn't open the app? Is there a way to update the live activity without using push notifications?
