IOS PayPal:如何允许用户在PayPal的付款页面上输入任何金额

Question

我使用以下代码将PayPal集成到我的应用程序中：

- (IBAction)MakePayment:(id)sender
{
    PayPalItem * item1 = [PayPalItem itemWithName:@"Item" withQuantity:1 withPrice:[NSDecimalNumber decimalNumberWithString:@"0.04"] withCurrency:@"USD" withSku:@"SKU-Item"];
    NSArray * items = @[item1];
    NSDecimalNumber * subtotal = [PayPalItem totalPriceForItems:items];
    NSDecimalNumber * shipping = [[NSDecimalNumber alloc]initWithString:@"0.0"];
    NSDecimalNumber * tax = [[NSDecimalNumber alloc]initWithString:@"0.0"];
    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 = @"USD";
    payment .shortDescription = @"My Payment";
    payment.items = items;
    payment.paymentDetails = paymentDetails;
    if(!payment.processable)
    {
    }
    PayPalPaymentViewController * paymentViewController = [[PayPalPaymentViewController alloc]initWithPayment:payment configuration:self.payPalconfig delegate:self];
    [self presentViewController:paymentViewController animated:YES completion:nil];
}

在此代码中，我通过代码输入了金额。但根据要求，用户必须在付款页面上手动输入任何金额。请向我建议任何代码，通过这些代码，我可以允许用户通过显示金额字段在付款页面上手动输入金额。

Answer 1

如果要允许用户输入或选择价格，请在控制器出现之前要求用户使用文本字段手动输入PayPal。

您无法PayPal控制器中输入价格。然后，您可以在PayPal控制器中传递价格值。
