Apple Pay Detective Wallet Does Not Have Credit Cards

Question

I am trying to implement Apple Pay for my application. I have a PKPaymentAuthorizationViewController trying to download Apple Pay View. This view manager was returned by the constructor as Nil, if I did not have any cards already in my wallet. So, I decided to guide the user, although the process is when they enter information about their card. I was able to achieve this using

PKPassLibrary* lib = [[PKPassLibrary alloc] init]; [lib openPaymentSetup]; 

Here is the part where I have PKPaymentAuthorizationViewController initialization. This returns a valid object on the Simulator showing the view. But on a real device without a configured credit card, nil is returned and an exception is thrown at runtime. Here is the initialization code:

 if ([PKPaymentAuthorizationViewController canMakePayments]) { // init arr [arr addObject:total]; request.paymentSummaryItems = arr; PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request]; paymentPane.delegate = self; [self presentViewController:paymentPane animated:TRUE completion:nil]; } 

Here the array is a valid NSArray PKPaymentSummaryItem, so it works successfully on the simulator.

I need to call the above openPaymentSetup method, every time I see a user without a credit card in my wallet. Is there any way to detect this?

I am currently using

 if ( [PKPassLibrary isPassLibraryAvailable] ) { PKPassLibrary* lib = [[PKPassLibrary alloc] init]; if ([lib passesOfType:PKPassTypePayment].count == 0 ) { [lib openPaymentSetup]; } } 

But this will not work, as I look at the number of passes in the wallet. Which can be like a boarding pass for an airline, or an eventbrite pass, etc.

Looked: PKPaymentAuthorizationViewController is present as a nil view controller

Apple pays PKPaymentauthorizationViewController always returns nil on boot using a payment request

I did as @maddy suggested, and it really worked. Unfortunately, the apple has very limited documentation about this. Thanks Maddy.

Here is my code

 -(BOOL) openAddCardForPaymentUIIfNeeded { if ( [PKPassLibrary isPassLibraryAvailable] ) { if ( ![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:[NSArray arrayWithObjects: PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa, nil]] ) { UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Add a Credit Card to Wallet" message:@"Would you like to add a credit card to your wallet now?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil]; [alert show]; return true; } } return false; } 

Now I am directing the user to add the card wizard to the wallet application. Is there a way to return the user to the application after he / she has finished adding the card to the Wallet?

Thanks!
