MGStoreKit - A lightweight blocks based StoreKit wrapper

All requests are asynchronous. Success and failure callbacks are executed on the main thread.

Fetch product data

NSString *itemKey = @"com.bigpaua.CoolApp.CoolFeature";
[[MGStoreKit store] requestProductsData:[NSSet setWithObject:itemKey]
    callback:^(NSArray *products) {
        for (SKProduct *product in products) {
            NSLog(@"Product Name:%@", product.localizedTitle);
            NSLog(@"Product Price:%@", product.price);
        }
    }];

SKProducts are cached per app run, so future requests for the same SKProduct will return immediately within the same run loop.

Purchase a product

if (![MGStoreKit store].canMakePayments) {

    NSLog(@"Not going to happen. The user can't make payments.");

} else {

    NSString *itemKey = @"com.bigpaua.CoolApp.CoolFeature";
    [[MGStoreKit store] purchaseProduct:itemKey success:^(NSString *productId) {

        // It's your responsibility to save the purchases to keychain, Core Data, 
        // or elsewhere. As a lightweight wrapper, MGStoreKit leaves these app 
        // level details up to you.
        
        NSLog(@"Purchased:%@", productId);

    } failed:^(NSString *productId) {

        // Failure is most likely the user changing their mind and tapping Cancel.
        
        NSLog(@"Failed:%@", productId);
    }];
}

Restore previous purchases

[[MGStoreKit store] restore:^(NSArray *restored) {
    for (NSString *productKey in restored) {

        // It's your responsibility to save the restored purchases to keychain, 
        // Core Data, or elsewhere. As a lightweight wrapper, MGStoreKit leaves 
        // these app level details up to you.

        NSLog(@"restored:%@", productKey);
    }
}];
