应用更新时设置图标徽章

Question

My app contains a number of embedded exercises that are shown to the user during app usage. I plan to release regular updates of my app that contain additional exercises. After each (standard appstore app) update I would like to add a badge to the app icon showing the number of new exercises (=diff between old nbr and new update nbr exercises).

I would like to add the badge without the user needing to start the app, immediatly and automatically after the update.

How can this be done? When ios updates your app, does it run for a brief period? In that case the logic could be implemented at that point....

Answer 1

Sounds like you're going to want to use a remote notification (aka Push) thats scheduled after you release an update. Apple Push Notifications

The issue with this is the user might not update automatically (or refuse an update). So maybe you can have a push that says "We just released an update with X new exercises!", rather than implying they already have the data.

Try this

  [[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];

To do this through local notification you have to set the value in applicationIconBadgeNumber

UILocalNotification *localNotification = [[UILocalNotification alloc] init];

localNotification.applicationIconBadgeNumber = 1;// set here the value of badge
