iphone - 在应用程序中购买 SKProductsRequest 在 ios 5 中崩溃我的应用程序

Question

我的商店工具包类因 SKProductsRequest 开始而崩溃 我没有体验过应用程序购买概念 我的类在 iOS 4.3 sdk 而非 iOS 5 sdk 中完美运行。在 SKProductsRequest 启动之前，我没有在控制台上收到错误消息并且我的应用程序崩溃了请任何人帮助我如何解决此问题这是我的代码:

#import "StorePurchase.h"

@implementation StorePurchase
@synthesize request = _request;

- (void)loadStore {

    if ([SKPaymentQueue canMakePayments]) {
        NSLog(@"Parental-controls are disabled");
        self.request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"com.mycompany.app"]];
        self.request.delegate = self;
        [self.request start];
    }
    else {
        NSLog(@"Parental-controls are enabled");
    }

}
static bool hasAddObserver=NO;

- (void)purchase {
    if (!hasAddObserver) {//flag to fix this bug
        /*=====================================*/
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
        hasAddObserver=YES;
    }
    SKMutablePayment *payment = [[SKMutablePayment alloc] init] ;
    payment.productIdentifier = @"com.mycompany.app";
    payment.quantity = 1;
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    SKProduct *validProduct = nil;
    int count = [response.products count];
    if (count > 0) 
    {
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products found,Magic Box!");
        [[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:@"Product Found..!"];

    } else if (!validProduct) 
    {
        NSLog(@"No products available");
        [[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:@"Product Not Found..!"];

    } 
}

- (void)provideContent:(NSString *)productIdentifier {

    NSLog(@"Toggling flag for: %@", productIdentifier);
    [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
    [[NSUserDefaults standardUserDefaults] synchronize];
    //[_purchasedProducts addObject:productIdentifier];

    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchasedNotification object:productIdentifier];

}

- (void)completeTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"completeTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"restoreTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.originalTransaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)failedTransaction:(SKPaymentTransaction *)transaction {

    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        NSLog(@"Transaction error: %@", transaction.error.localizedDescription);
    }

    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseFailedNotification object:transaction];
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}

- (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error
{
    NSLog(@"<><Canceled!><>");
    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseCanceledNotification object:error];


}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {


    for (SKPaymentTransaction *transaction in transactions) {

        switch (transaction.transactionState) {

            case SKPaymentTransactionStatePurchasing:
                // [self completeTransaction:transaction];
                break;

            case SKPaymentTransactionStatePurchased:
                NSLog(@"Purchased");
                [self completeTransaction:transaction];
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                break;

            case SKPaymentTransactionStateRestored:
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                NSLog(@"Restored");
                [self restoreTransaction:transaction];

                break;

            case SKPaymentTransactionStateFailed:
                if (transaction.error.code != SKErrorPaymentCancelled) {
                    NSLog(@"An error encounterd");
                }
                else {
                    NSLog(@"Cancelled!");
                }
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                [self failedTransaction:transaction];

                break;

        }

    }


}

我在得到错误后调用loadStore方法

SKProductsRequest 在我的应用程序崩溃之前没有调用 - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response 方法!

我的代码有什么问题如何解决!提前致谢!

Answer 1

我已经使用这段代码在我的应用程序中完成了 inapppurchase 的代码，没有任何问题

- (void)loadStore
{
// restarts any purchases if they were interrupted last time the app was open
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

// get the product description (defined in early sections)
[self requestProUpgradeProductData];
}

- (void)requestProUpgradeProductData
{
NSSet *productIdentifiers = [NSSet setWithObject:kInAppPurchaseProUpgradeProductId];
productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
productsRequest.delegate = self;
[productsRequest start];

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

之后它会调用这个方法

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSArray *products = response.products;
proUpgradeProduct = [products count] == 1 ? [[products objectAtIndex:0] retain] : nil;
if (proUpgradeProduct)
{
    NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
    NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
    NSLog(@"Product price: %@" , proUpgradeProduct.price);
    NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
    if ([self canMakePurchases]) {
        if ([self respondsToSelector:@selector(purchaseProUpgrade)]) {
            [self purchaseProUpgrade];
        }
    }
    else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[self languageSelectedStringForKey:@"Error"] message:@"Cannot connect to Store.\n Please Enable the Buying in settings" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alert show];
        [alert release];
    }
}

for (NSString *invalidProductId in response.invalidProductIdentifiers)
{
    [SVProgressHUD dismiss];
    [cancelButton setEnabled:YES];
    [buyNowButton setEnabled:YES];
    [restoreButton setEnabled:YES];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Warning" message:@"Error occured" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
    [alert show];
    [alert release];
    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];
}
- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
[self recordTransaction:transaction];
[self provideContent:transaction.payment.productIdentifier];
[self finishTransaction:transaction wasSuccessful:YES];
}
- (void)purchaseProUpgrade
{
[SVProgressHUD showInView:self.view status:[self languageSelectedStringForKey:@"Connecting Store"] networkIndicator:YES];
SKPayment *payment = [SKPayment paymentWithProductIdentifier:kInAppPurchaseProUpgradeProductId];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (void)recordTransaction:(SKPaymentTransaction *)transaction
{
if ([transaction.payment.productIdentifier isEqualToString:kInAppPurchaseProUpgradeProductId])
{
    // save the transaction receipt to disk
    [[NSUserDefaults standardUserDefaults] setValue:transaction.transactionReceipt forKey:@"proUpgradeTransactionReceipt" ];
    [[NSUserDefaults standardUserDefaults] synchronize];
}
}

最后这个方法

- (void)finishTransaction:(SKPaymentTransaction *)transaction wasSuccessful:(BOOL)wasSuccessful
{
// remove the transaction from the payment queue.
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:transaction, @"transaction" , nil];
if (wasSuccessful)
{
//Write your transaction complete statement required for your project
}
