IPhone Icon - Red Indicators #

Question

How do you implement red number indicators (e.g. notification of the number of email messages)?

Answer 1

What you are looking for is a property applicationIconBadgeNumberthat is a property UIApplication.

To install the icon from anywhere in your application, use:

UIApplication *application = [UIApplication sharedApplication];
application.applicationIconBadgeNumber = 1; // set to any integer

To remove the icon, set the property to 0.

Answer 2

What you want is called an "icon."

[UIApplication sharedApplication].applicationIconBadgeNumber = 2;
