How do I hide an iAd banner once a non-consumable "Remove Ads" In-App Purchase has been made? I'm not quite sure how to do that or where to do that, according to this tutorial.
Any help would be greatly appreciated!
Thank you

You should NSUserDefaults.
Put at the top of both .m files:
#define SHOW_ADS_KEY @"Show Ads Key"
When the user has purchased the IAP you do this (in IAP.m):
- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers {
if ((self = [super init])) {
// Store product identifiers
_productIdentifiers = productIdentifiers;
// Check for previously purchased products
_purchasedProductIdentifiers = [NSMutableSet set];
for (NSString * productIdentifier in _productIdentifiers) {
BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier];
if (productPurchased) {
[_purchasedProductIdentifiers addObject:productIdentifier];
NSLog(@"Previously purchased: %@", productIdentifier);
// NEW CODE
if ([productIdentifier isEqualToString:@"com.GPS.iapra"]){
[[NSUserDefaults standardUserDefaults] setObject: @"No" forKey:SHOW_ADS_KEY];
[[NSUserDefaults standardUserDefaults] synchronize];
}
// NEW CODE ^^
} else {
NSLog(@"Not purchased: %@", productIdentifier);
}
}
// Add self as transaction observer
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}
For the ad code (in VC.m):
- (void)viewWillAppear {
if (![[[NSUserDefaults standardUserDefaults] objectForKey:SHOW_ADS_KEY] isEqualToString: @"No"]){ // NEW CODE
// Code to show ads
PokeABowlAd.hidden = NO;
} else {
PokeABowlAd.hidden = YES;
}
NSLog(@"Shows ads?: %@", [[NSUserDefaults standardUserDefaults] objectForKey:SHOW_ADS_KEY]);
}
Now modify completeTransaction:
- (void)completeTransaction:(SKPaymentTransaction *)transaction {
NSLog(@"completeTransaction...");
if ([transaction.payment.productIdentifier isEqualToString:@"com.GPS.iapra"]){
[[NSUserDefaults standardUserDefaults] setObject: @"No" forKey:SHOW_ADS_KEY];
[[NSUserDefaults standardUserDefaults] synchronize];
}
[self provideContentForProductIdentifier:transaction.payment.productIdentifier];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
