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。请建议我通过显示金额字段，允许用户在付款页面上手动输入金额的任何代码。

Answer 1

如果您想允许您的用户输入或选择价格，请在paypal控制器出现之前让用户手动输入textfield。

您无法在paypal控制器中输入价格。然后你可以在paypal控制器中传递价格值。
