Final answer:
To view notification counts on an iPhone app icon, enable the Badge App Icon option in the Notifications section of the device's Settings app.
Step-by-step explanation:
To get the notification count on an iPhone app icon, ensure that badge app notifications are enabled for the respective application. First, open the Settings app on your iPhone. Scroll down and tap on Notifications. Find and select the app you want to manage notifications for. Then, toggle Badge App Icon to ON if it isn't already. This will allow the app to show a red badge with the notification count on the app icon whenever there are unread or unaddressed notifications.
To get the notification count on the iPhone app icon, you can use the UNUserNotificationCenter class in iOS. First, you need to request permission from the user to display notifications. Once you have the permission, you can set the application badge number to display the count on the app icon.Keep in mind that the exact steps may vary slightly depending on the iOS version. App developers can also provide additional notification settings within the app itself, which may influence the badge count that appears on its icon.
