Objective c paypal iOS集成

我按下了按钮，当我按下它时，我调用了这个方法，在iPhone simulator 5上，我得到了错误，在iPhone simulator 4.3上工作成功，但在多次按下按钮后：

- (void)simplePayment {
//dismiss any native keyboards

[PayPal initializeWithAppID:@"APP-80W284485P519543T" forEnvironment:ENV_SANDBOX];

//optional, set shippingEnabled to TRUE if you want to display shipping
//options to the user, default: TRUE
[PayPal getPayPalInst].shippingEnabled = TRUE;

//optional, set dynamicAmountUpdateEnabled to TRUE if you want to compute
//shipping and tax based on the user's address choice, default: FALSE
[PayPal getPayPalInst].dynamicAmountUpdateEnabled = TRUE;

//optional, choose who pays the fee, default: FEEPAYER_EACHRECEIVER
[PayPal getPayPalInst].feePayer = FEEPAYER_EACHRECEIVER;

//for a payment with a single recipient, use a PayPalPayment object
PayPalPayment *payment = [[[PayPalPayment alloc] init] autorelease];
payment.recipient = @"example-merchant-1@paypal.com";
payment.paymentCurrency = @"USD";
payment.description = @"Teddy Bear";
payment.merchantName = @"Joe's Bear Emporium";

//subtotal of all items, without tax and shipping
payment.subTotal = [NSDecimalNumber decimalNumberWithString:@"10"];

//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"];
payment.invoiceData.totalTax = [NSDecimalNumber decimalNumberWithString:@"0.35"];

//invoiceItems is a list of PayPalInvoiceItem objects
//NOTE: sum of totalPrice for all items must equal payment.subTotal
//NOTE: example only shows a single item, but you can have more than one
payment.invoiceData.invoiceItems = [NSMutableArray array];
PayPalInvoiceItem *item = [[[PayPalInvoiceItem alloc] init] autorelease];
item.totalPrice = payment.subTotal;
item.name = @"Teddy";
[payment.invoiceData.invoiceItems addObject:item];

[[PayPal getPayPalInst] checkoutWithPayment:payment];

}
