需要加入StoreKit.framework有app内置购买项目

The approach of getting the country code of the user's locale will work ... but only if the user's iTunes store is the same as their locale. This won't always be the case. 

If you create an in-app purchase item, you can use Apple's StoreKit APIs to find out the user's actual iTunes country even if it's different from their device locale. Here's some code that worked for me:

- (void) requestProductData
{
SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:
[NSSet setWithObject: PRODUCT_ID]];
request.delegate = self;
[request start];
}

- (void) productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSArray *myProducts = response.products;
for (SKProduct* product in myProducts) {
NSLocale* storeLocale = product.priceLocale;
storeCountry = (NSString*)CFLocaleGetValue((CFLocaleRef)storeLocale, kCFLocaleCountryCode);
NSLog(@"Store Country = %@", storeCountry);
}

[request release];

// If product request didn't work, fallback to user's device locale
if (storeCountry == nil) {
CFLocaleRef userLocaleRef = CFLocaleCopyCurrent();
storeCountry = (NSString*)CFLocaleGetValue(userLocaleRef, kCFLocaleCountryCode);
}

// Now we're ready to start creating URLs for the itunes store
[super start];
}

- (NSString *)getUserCountry

return [locale objectForKey: NSLocaleCountryCode];
