iPhone App Link To App Update in AppStore

Does anyone know if you can send a user to an app's update in the appstore?

We want to do this from within the app and/开发者_运维问答or when getting a Push Notification.

Thanks!

Yes, it is possible as long as you have the URL that links to your app.

I'm not 100% sure, but I seem to remember seeing something in the apple rules that means you may not be able to send a push notification advertising new apps. But an update may be ok.

Remember as well that a user may have already updated the app because they had the badge on the AppStore icon and then you push a notification out to all users. Could be annoying.
