我正在探索是否有可能实现我在 iOS 中的想法。然而，这个想法取决于能够给用户钱。这在iOS中可能吗？我知道 Apple 希望您在从用户那里收钱（应用内购买等）时使用 StoreKit ，但 StoreKit 中是否有一种机制可以向用户提供资金，如果没有，iOS 规则是否允许使用第三个 -像 PayPal 这样的派对服务给用户钱？

是的，您可以使用 Paypal 等第三方服务进行付款。要实现 Paypal 机制，请执行以下步骤。

1)在此处下载适用于 iOS 的移动支付库表格

2) 在视图控制器的头文件中导入 PayPal.h 文件。

3）在项目中包含以下框架——Security.framework、MapKit、ImageIO、SystemConfiguration

4) 还包括以下两个库文件 - libz.dylib、libxml2.dylib

5）创建一个支付按钮，如

     UIButton checkOutBtn=[[PayPal getPayPalInst] getPayButtonWithTarget:self andAction:@selector(payWithPayPal) andButtonType:BUTTON_152x33 andButtonText:BUTTON_TEXT_PAY];
     checkOutBtn.frame=CGRectMake(60, 100, 200, 45);
     [self.view addSubview:checkOutBtn];

6）使用以下代码实现按钮操作方法：

    -(void) payWithPayPal
    {
           [PayPal getPayPalInst].shippingEnabled=TRUE;
           [PayPal getPayPalInst].dynamicAmountUpdateEnabled=TRUE;
           [PayPal getPayPalInst].feePayer=FEEPAYER_EACHRECEIVER;

           PayPalPayment *payment=[[[PayPalPayment alloc] init] autorelease];
           payment.recipient=@"xyz@paypal.com";
           payment.paymentCurrency=@"USD";

           payment.description = @"Paypal";
           payment.merchantName = @"Title Name";

           //subtotal of all items, without tax and shipping

           payment.subTotal = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:@"%1.2f", 5320.50 ]];   // total Price

          //invoiceData is a PayPalInvoiceData object which contains tax, shipping, and a list of PayPalInvoiceItem objects

           payment.invoiceData = [[[PayPalInvoiceData alloc] init] autorelease];
           payment.invoiceData.totalShipping = [NSDecimalNumber decimalNumberWithString:@"2"];   // Shipping Cost
           payment.invoiceData.totalTax = [NSDecimalNumber decimalNumberWithString:@"0.35"];   // Tax On Product

           //invoiceItems is a list of PayPalInvoiceItem objects
           //NOTE: sum of totalPrice for all items must equal payment.subTotal

           payment.invoiceData.invoiceItems = [NSMutableArray array];
           PayPalInvoiceItem *item = [[[PayPalInvoiceItem alloc] init] autorelease];

           item.totalPrice = payment.subTotal;
           item.name = @"Product Name";
           [payment.invoiceData.invoiceItems addObject:item];

           [[PayPal getPayPalInst] checkoutWithPayment:payment];
    }

7) 使用以下代表

    -(void)paymentSuccessWithKey:(NSString *)payKey andStatus:(PayPalPaymentStatus)paymentStatus
    {
           NSLog(@"Successfully Paid");
    }
    -(void)paymentCanceled
    {
           NSLog(@"Cancelled");
    }
    - (void)paymentFailedWithCorrelationID:(NSString *)correlationID
    {
           NSLog(@"Failed");
    }
    -(void)paymentLibraryExit
    {
           NSLog(@"Exit");
    }
