流星-如何检测应用程序是否已打开？

Question

I'm running a Meteor app on IOS and I'd like to reset the badge number to 0 when the app is opened. My logic is to set the badge to zero whenever the app is opened, and increment it until it is opened again. How can I see if an app was pressed/opened? Meteor.startup doesn't seem to work. Is there some method called when the app is opened?

Answer 1

In your AppDelegate.m :

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    // set badge to 0

Answer 2

You could put a script in a template onCreated section, eg

Template.example.onCreated(function(){
    //run your function here
});

Or put it in a template helper if you rely on reactive data.

Answer 3

This seems late, but for future reference: You don't need to increment/decrement badge count manually. Just add the properties badge and clearBadge in your client side Push Configuration on Meteor.startup like this:

Meteor.startup(() => {
    Push.Configure({
      ios: {
        alert: true,
        badge: true,
        sound: true,
        clearBadge: true
      }
    })
});

This will increment your badgeCount as soon as a notification arrives and will set the count to 0 when the user opens the app.
