How does swift add messages to the IOS app icon and add swiftios

You can add a Message count reminder in the upper-right corner of the application icon to conveniently notify you of any new messages to be processed in the application. The following uses xcode 7.3.1 to briefly describe how to implement this function in swift.

1. Modify AppDelegate. swift

2. Modify the value in ViewController. swift.

3 compile and run

The first dialog box will pop up asking whether messages can be pushed. After confirmation, after running the app for the second time, the number of messages will be marked in the upper-right corner of the icon, as shown in:
