應用內購買耗材型號中的問題

Question

我創建了一款非消費型應用內購買物品，現在我想創建一個消費型應用內購買物品，用戶每次使用In-應用購買。現在什麼都會有在不同的模型下面的代碼更改： -

在應用程式內購買manager.m ：

@implementation InAppPurchaseManager 


//@synthesize purchasableObjects; 
//@synthesize storeObserver; 
@synthesize proUpgradeProduct; 
@synthesize productsRequest; 


//BOOL featureAPurchased; 
//BOOL featureBPurchased; 

//static InAppPurchaseManager* _sharedStoreManager; // self 

- (void)dealloc { 

    //[_sharedStoreManager release]; 
    //[storeObserver release]; 
    [super dealloc]; 
} 




- (void)requestProUpgradeProductData 
{ 
    NSSet *productIdentifiers = [NSSet setWithObject:@"com.comp_name.iWorkOut1" ]; 
    productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; 
    productsRequest.delegate = self; 
    [productsRequest start]; 

    // we will release the request object in the delegate callback 
} 



#pragma mark - 
#pragma mark SKProductsRequestDelegate methods 
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response 
{ 
    //NSArray *products = response.products; 
    //proUpgradeProduct = [products count] == 1 ? [[products firstObject] retain]: nil; 

    if (proUpgradeProduct) 
     { 
      NSLog(@"Product title: %@", proUpgradeProduct.localizedTitle); 
      NSLog(@"Product description: %@", proUpgradeProduct.localizedDescription); 
      NSLog(@"Product price: %@", proUpgradeProduct.price); 
      NSLog(@"Product id:%@", proUpgradeProduct.productIdentifier); 
     } 

    /*for (NSString *invalidProductId in response.invalidProductIdentifiers) 
     { 
      NSLog(@"Invalid product id: %@" , invalidProductId); 
     }*/ 

    //finally release the reqest we alloc/init’ed in requestProUpgradeProductData 
    [productsRequest release]; 

    [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerProductsFetchedNotification object:self userInfo:nil]; 
} 



#pragma -

/* call this method once on startup*/

在SKProduct.m

： -

@implementation SKProduct (LocalizedPrice) 
- (NSString *)localizedPrice 
{ 
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; 
    [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; 
    [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; 
    [numberFormatter setLocale:self.priceLocale]; 
    NSString *formattedString = [numberFormatter stringFromNumber:self.price]; 
    [numberFormatter release]; 
    return formattedString; 
}

我建議你看看InventoryKit，它支持應用程序購買中的非消費品，消費品和訂閱，並且是開源的。
