PayPal SDK for iOS - ios

Question

I am trying to implement the Paypal SDK into my iOS app. I copied the code exactly from the Readme instructions, imported the files, and linked my button to my action but when I clicked the button it gives me a "Thread 1 signal:SIGABRT" error and crashes.
Here is the Paypal code in my .m files:
- (IBAction)pay {
// Create a PayPalPayment
PayPalPayment *payment = [[PayPalPayment alloc] init];
payment.amount = [[NSDecimalNumber alloc] initWithString:#"39.95"];
payment.currencyCode = #"USD";
payment.shortDescription = #"Product";
// Check whether payment is processable.
if (!payment.processable) {
// If, for example, the amount was negative or the shortDescription was empty, then
// this payment would not be processable. You would want to handle that here.
}
// Provide a payerId that uniquely identifies a user within the scope of your system,
// such as an email address or user ID.
NSString *aPayerId = #"someone#someone.com";
// Create a PayPalPaymentViewController with the credentials and payerId, the PayPalPayment
// from the previous step, and a PayPalPaymentDelegate to handle the results.
PayPalPaymentViewController *paymentViewController;
paymentViewController = [[PayPalPaymentViewController alloc] initWithClientId:#"MY-CLIENT-ID-HERE"
receiverEmail:#"MY-EMAIL-HERE"
payerId:aPayerId
payment:payment
delegate:self];
// Present the PayPalPaymentViewController.
[self presentViewController:paymentViewController animated:YES completion:nil];
}
#pragma mark - PayPalPaymentDelegate methods
- (void)payPalPaymentDidComplete:(PayPalPayment *)completedPayment {
// Payment was processed successfully; send to server for verification and fulfillment.
[self verifyCompletedPayment:completedPayment];
// Dismiss the PayPalPaymentViewController.
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)payPalPaymentDidCancel {
// The payment was canceled; dismiss the PayPalPaymentViewController.
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)verifyCompletedPayment:(PayPalPayment *)completedPayment {
// Send the entire confirmation dictionary
NSData *confirmation = [NSJSONSerialization dataWithJSONObject:completedPayment.confirmation
options:0
error:nil];
// Send confirmation to your server; your server should verify the proof of payment
// and give the user their goods or services. If the server is not reachable, save
// the confirmation and try again later.
}
Does anyone have any ideas what the problem might be?

Answer 1

You know what?
cuz you use decimal number on you currency.
so you need do something in this code
// Check whether payment is processable.
if (!payment.processable) {
// If, for example, the amount was negative or the shortDescription was empty, then
// this payment would not be processable. You would want to handle that here.
}
If you in debug point you can find a keyword in payment, display, it's mean your currency will change to 40.0.
Try it.
