iphone application update

Question

hi,

i would like to check:

if a user downloaded my app, than i make some update to app, data etc., itunes will auto remind the user of the update through app store, and the user can update for free? or do i have to set such reminder in my application?

else, is there a way for me to send this notification?

thks

Answer 1

Yes, the phone notifies of app updates through the App Store app and app updates are free.

Alternatively, you can use push notifications to notify the user that a new version is available, or display an alert the next time they open the app.

To do the latter you can query the version of the app ([[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];) and compare it to a value provided by your web server.
