Is it possible to implement In-App Purchases only for a subset of countries?

Question

Is there a way to use In-App Purchases such that they're NOT available in the USA, and at the same time figure out if they're available or not - and if not, perform special tasks for customers in the USA who can't use them?

Answer 1

You could use CLLocationManager to find the users location and then use MKReverseGeocoder to figure out what country they are in.

Some people will deny access to location information. As a backup you could use the language that the current device is in (but there are some obvious issues with this approach):

NSString * language = [[NSLocale preferredLanguages] objectAtIndex:0];

Then you just need to use a conditional statement:

if(in USA){ 
  do whatever, don't allow in-app purchases
} else {
  allow in app purchases
}
