Paypal ios SDK即使调用[PayPalMobile clearAllUserData]也不会清除以前使用的信用卡

Question

I'm integrating Paypal ios SDK version 2.1 into my app but have run into a problem. The SDK seems to keep past payment cards in memory even though i call [PayPalMobile clearAllUserData] after the payment has been completed.

@interface AirliftCartViewController : AirliftViewController <AVCaptureMetadataOutputObjectsDelegate, UITableViewDelegate, AirliftCartTotalsChangeDelegate, PayPalPaymentDelegate>
    @property (strong) AVCaptureSession * captureSession;
    @property (strong, nonatomic) UIView *cameraPreview;
    @property (nonatomic, strong, readwrite) PayPalConfiguration *payPalConfiguration;
    - (IBAction)initiateCreditCardCheckout:(id)sender;
@end
...
@implementation AirliftCartViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil timeout:(NSUInteger)timeoutInSeconds screenName:(NSString *)screenName
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil timeout:timeoutInSeconds screenName:@"AirliftCartView"];
    if (self) {
        // Custom initialization
        self.payPalConfiguration = [[PayPalConfiguration alloc] init];
        self.payPalConfiguration.rememberUser = NO;
    }

    return self;
}



- (void)payPalPaymentDidCancel:(PayPalPaymentViewController *)paymentViewController
{
    NSLog(@"payment cancelled!");
    // The payment was canceled; dismiss the PayPalPaymentViewController.
    [paymentViewController dismissViewControllerAnimated:YES completion:^{
        // clear all paypal user information
        [PayPalMobile clearAllUserData];
    }];
}

- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment
{
    NSLog(@"Payment was successful");
    // Payment was processed successfully; send to server for verification and fulfillment.
    [self verifyCompletedPayment:completedPayment];

    // Dismiss the PayPalPaymentViewController.
    [paymentViewController dismissViewControllerAnimated:YES completion:^{

    // clear all paypal user information
    [PayPalMobile clearAllUserData];

    // emptycart
    [self.cartController emptyCart];

    // reset metadata
    [self.metaDataFound removeAllObjects];

}

- (IBAction)initiateCheckout:(id)sender {
    NSLog(@"checkout requested!");
    [PayPalMobile preconnectWithEnvironment:PayPalEnvironmentSandbox];

    // present paypal payment
    PayPalPaymentViewController * payPalVC = [[PayPalPaymentViewController alloc]
                                          initWithPayment:[self.cartController getPayPalPaymentFromCart]
                                          configuration:self.payPalConfiguration delegate:self];

    [self presentViewController:payPalVC animated:YES completion:^{
        [self.captureSession stopRunning];
        [self.cameraPreview removeFromSuperview];
    }];
}


@end

I present the PayPalPaymentViewController like this (so there's no strong reference to it that i can tell)

Its not acceptable that any card information is kept retained for my app, any ideas anyone?

Edit: Adding user steps as requested:

• the user selects products to buy and then clicks on checkout button which has initiateCheckout as its Action.
• this brings up the paypalpaymentviewcpntroller which shows the previously used card as the only payment option (the first time I launch the controller provides a choice of either logging into paypal or using a card)

Edit 2: Added property declarations for captureSession and cameraPreview and expanded init definition

Edit 3: Added screenshots

Dave from PayPal here.

A few questions:

(1) What's going on with your captureSession and cameraPreview ?

(2) Could you please provide a series of specific steps, from the user's perspective, that reproduce your problem?

(3) What is the indication that the SDK is keeping card data in memory?

(4) Which version of the SDK are you running? I'm guessing that it's the one of the most recent versions, 2.1.5 or 2.1.6?

* EDIT (1 August 2014): The originally described bug has been fixed in our latest release . *

您还可以在PayPalConfiguration https://github.com/paypal/PayPal-iOS-SDK/blob/master/PayPalMobile/PayPalConfiguration.h#L57中设置remeberUser = NO，这样SDK甚至不会尝试保存任何内容。
