IAPManager

Yet Another simple in-app purchase interface for iOS.

A simple toolkit for non-renewables (a.k.a "Premium Features") with In-App Purchase. The main goal is ease of use. Therefore, more complicated parts, like checking of receipts, are not provided.

Features

• Simple setup
• Efficient one-line check if a product was purchased
• SKProducts to obtain prices
• Restoring purchases
• Uses block for callbacks

Requirements

iOS 5 or above with ARC and StoreKit.framework.

How-to

1. Create your purchases in iTunes Connect. For details see the In-App Purchase Programming Guide.
2. Add StoreKit.framework to your project
3. Add IAPManager.h and IAPManager.m into your project, or use the Pod IAPManager.
4. Create your IAP UI

5. Use the methods of the [IAPManager sharedIAPManager] singleton:

   • Check if the App Store is available: [[IAPManager sharedIAPManager] canPurchase]

   • To obtain product information:

     [[IAPManager sharedIAPManager] getProductsForIds:@[@"superpremiumversion"]
                                   completion:^(NSArray *products) {
                                       BOOL hasProducts = [products count] != 0;
                                       if(! hasProducts) {
                                           NSLog(@":(");
                                       }
                                       else {
                                           SKProduct *premium = products[0];
     
                                           NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];                                                                                                                 [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
                                           [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
                                           [numberFormatter setLocale:premium.priceLocale];
                                           NSString *formattedPrice = [numberFormatter stringFromNumber:premium.price];
                                           NSLog(@"super premium: %@ for %@", premium.localizedTitle, formattedPrice);
                                       }
     }];

   • To purchase a product:

     [[IAPManager sharedIAPManager] purchaseProductForId:@"superpremiumversion"
                                      completion:^(SKPaymentTransaction *transaction) {
                                          [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
                                          UIAlertView *thanks = [[UIAlertView alloc] initWithTitle:@"Thanks!"
                                                                                           message:@"The extra features are now available"
                                                                                          delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                                          [thanks show];
                                      } error:^(NSError *err) {
                                          [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
     
                                          NSLog(@"An error occured while purchasing: %@", err.localizedDescription);
                                          // show an error alert to the user.
                                      }];

     StoreKit will then ask the user if they want to purchase the product.
