価格と商品の合計を取得し、Paypalに送信するiOS

Question

iOSのPayPal SDKを使用しています。 1つの製品の総量をpayPal SDKに渡すと、完全に機能します。しかし、カート内に1つ以上の商品があり、各商品の金額と数量が異なる場合は、合計金額をPayPalに引き渡す方法を教えてください。私がそれから出るのを助けてください。私は "ユーロ"通貨形式で価格を計算して渡しています。前もって感謝します。私のコードは次のとおりです。 -

 - (IBAction)paypalButtonForSubmitData:(id)sender 
     { 
      NSDecimalNumber *subTotal;  
      NSArray *items;  
      self.resultText = nil;  
    // Here _arrayToCarryDataFromCartToPaymentPageInPaypal is array through which I am getting data from Plist.   
     for (int j=0; j<_arrayToCarryDataFromCartToPaymentPageInPaypal.count; j++) 
      { 
       NSMutableDictionary *paypalArrayDataInDictionary=[_arrayToCarryDataFromCartToPaymentPageInPaypal objectAtIndex:j];  
// priceDetail is giving me the price of any particular product. 
       NSString *priceDetail=[paypalArrayDataInDictionary objectForKey:@"PRICE"];  
       NSString *stringWithoutSpaces = [priceDetail stringByReplacingOccurrencesOfString:@"€" withString:@""]; 
       NSLog(@"Price=%@",stringWithoutSpaces); 
       PayPalItem *item1=[PayPalItem itemWithName:@"IPHONE" withQuantity:[[paypalArrayDataInDictionary objectForKey:@"STOCK"]intValue] withPrice:[NSDecimalNumber decimalNumberWithString:stringWithoutSpaces] withCurrency:@"EUR" withSku:@"SKU-iPhone6"];  
       items= @[item1];  
       subTotal=[PayPalItem totalPriceForItems:items];  
       NSDecimalNumber *shipping=[[NSDecimalNumber alloc]initWithString:@"0,00"]; 
       NSDecimalNumber *tax=[[NSDecimalNumber alloc]initWithString:@"0,00"];  

       PayPalPaymentDetails *paymentDetails=[PayPalPaymentDetails paymentDetailsWithSubtotal:subTotal withShipping:shipping withTax:tax];  
       NSDecimalNumber *total=[[subTotal decimalNumberByAdding:shipping]decimalNumberByAdding:tax];  

       PayPalPayment *payment=[[PayPalPayment alloc]init];  
       payment.amount=total;  
       payment.currencyCode=@"EUR";  
       payment.shortDescription=@"My Payment";  
       payment.items=items;  
       payment.intent = PayPalPaymentIntentSale;  
       payment.paymentDetails=paymentDetails;  
       NSLog(@"Payment=%@",payment);  

       if (!payment.processable) {  
        NSLog(@"Error");  
       } 
       // self.payPalConfig.acceptCreditCards=self.acceptCreditCards;  
       PayPalPaymentViewController *paymentViewController=[[PayPalPaymentViewController alloc]initWithPayment:payment configuration:self.payPalConfig delegate:self];  
       [self presentViewController:paymentViewController animated:true completion:nil];  
      }  
     }  

Answer 1

あなたがループを開始する前に、コードの下に

PayPalPayment *payment=[[PayPalPayment alloc]init]; 

を宣言する必要があり、このため

のforループの外にPaypalViewControllerを提示するコードを記述してください。
