Key types of internal purchases:

1. SKPayment (SKMutablePayment can correspond one-to-one parameters to the payment generated by Apple)

2. TransactionObserver: This method is executed when the transaction status is updated. This method will pass in the transaction SKPaymentTransaction array, traverse the array, and perform corresponding operations on different states.

(SKPaymentTransactionStatePurchasing, SKPaymentTransactionStatePurchased, SKPaymentTransactionStateFailed, SKPaymentTransactionStateRestored, SKPaymentTransactionStateDeferred)

3. SKPaymentTransaction: Includes transactionreceept, payment, transactionIdentifier, and other key attributes. transactionReceipt is the key for backend signature verification.

 

Internal purchase process 1:

SKPayment * payment = [SKPayment paymentWithProductIdentifier: productID]; // input productID
[[SKPaymentQueue defaultQueue] addTransactionObserver: self]; // Add an observer and execute the Protocol to update the payment status

// Observer proxy method
-(Void) paymentQueue :( SKPaymentQueue *) queue updatedTransactions :( NSArray *) transactions
{
For (SKPaymentTransaction * transaction in transactions)
{
Switch (transaction. transactionState)
{
Case SKPaymentTransactionStatePurchased:
// Perform operations on the payment status
Break;
Case SKPaymentTransactionStateFailed:
// Failed payment operation
Break;
Case SKPaymentTransactionStateRestored:
// Operations on non-consumable products
Break;
Default:
Break;
}
}
}
If the user has already paid but the verification signature is not passed, a free recovery dialog box will be generated when the payment continues. In this case, even if the payment is added, it is in the purchasing status, you must pass [[SKPaymentQueue defaultQueue] finishTransaction: transaction] To the paymentque to execute the order in the purchasing State one by one (this is for the same productIdentifier product ), different productIdentifier products can still be paid normally
