在應用程序購買 - 購買錯誤的產品

Question

我是新手在ios編程，這是我第一次使用應用程序購買。我所有的IAP都是可以使用的，而且我的代碼沒有錯誤。但是，有些事情是錯誤的。因爲我用沙箱環境測試了我的IAP，當我試圖購買我的第一層物品時，警報視圖向我展示了第5層物品。

您可以檢查所有代碼約IAP：

@interface ViewController(){ 
    NSString *currencyString; 
    SKProduct *validProduct; 
} 

- (void)validateReceiptForTransaction:(SKPaymentTransaction *)transaction { 
VerificationController * verifier = [VerificationController sharedInstance]; 
[verifier verifyPurchase:transaction completionHandler:^(BOOL success) { 
    if (success) { 

     UIAlertView *tmp = [[UIAlertView alloc] 
          initWithTitle:@"Complete" 
          message:@"Transaction successful!" 
          delegate:self 
          cancelButtonTitle:nil 
          otherButtonTitles:@"Ok", nil]; 
     [tmp show]; 
     [self provideContentForProductIdentifier:transaction.payment.productIdentifier]; 
    } else { 

     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Purchase Unsuccessful" 
                 message:@"Your purchase failed. Please try again." 
                 delegate:self 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
     [alert show]; 

     [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
    } 
}]; 
} 

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

if ([productIdentifier isEqualToString:@"100LJ"]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 100; 

    [defaults setInteger:j forKey:@"j"]; 
    [defaults synchronize]; 
} 
else if ([productIdentifier isEqualToString:@"500LJ"]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 500; 

    [defaults setInteger:j forKey:@"j"]; 
    [defaults synchronize]; 
} 
else if ([productIdentifier isEqualToString:@"1000LJ"]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 1000; 

    [defaults setInteger:j forKey:@"j"]; 
    [defaults synchronize]; 
} 
else if ([productIdentifier isEqualToString:@"5000LJ"]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 5000; 

    [defaults setInteger:j forKey:@"j"]; 
    [defaults synchronize]; 
} 
else if ([productIdentifier isEqualToString:@"10000LJ"]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 10000; 

    [defaults setInteger:j forKey:@"j"]; 
    [defaults synchronize]; 
}

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    int j = [defaults integerForKey:@"j"]; 

    j += 50000; 

    [defaults setInteger:j forKey:@"j"];

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response

     [_storebuy7 setTitle:currencyString forState:UIControlStateNormal]; 
    } 
} 
} 

我有7個按鍵購買IAP項。 這是我的按鈕購買1級IAP項目：

- (IBAction)storebuy1:(UIButton *)sender{ 
_activityView=[[UIActivityIndicatorView alloc]  initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; 

[_activityView.layer setBackgroundColor:[[UIColor colorWithWhite: 0.0 alpha:0.30] CGColor]]; 

_activityView.center=self.view.center; 

_activityView.hidesWhenStopped = YES; 

[_activityView startAnimating]; 

[self.view addSubview:_activityView]; 


SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"100LJ"]]; 

request.delegate = self; 
[request start]; 

if ([SKPaymentQueue canMakePayments]) { 

    SKPayment *payment = [SKPayment paymentWithProduct:validProduct]; 
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; 
    [[SKPaymentQueue defaultQueue] addPayment:payment]; 

} 

else { 

    UIAlertView *tmp = [[UIAlertView alloc] 

         initWithTitle:@"Prohibited" 

         message:@"Parental Control is enabled!" 

         delegate:self 

         cancelButtonTitle:nil 

         otherButtonTitles:@"Ok", nil]; 

    [tmp show]; 
} 
} 

希望你能幫助我。

最好的問候， 塔哈

因爲validProduct設置爲不管它是最後一組時productsRequest:didReceiveResponse:叫對，那是不太可能是你想要的。

一般來說，你的方法是錯誤的。您應該爲所有產品標識符製作一個SKProductsRequest，然後存儲您找回的所有產品。您可以循環播放產品以更新您的按鈕標題（首先對產品進行排序）。當按下按鈕時，您應該找到具有適當標識符的產品並從中創建您的SKPayment。

因此，擺脫SKProduct *validProduct;而不是將產品存儲在數組或字典中。
