iphone - what is the alternative solution for paymentWithProductIdentifier?

Question

Hi i am using in APP purchase in my project . When i run this project everything works fine, except i am getting a warning message saying that "paymentWithProductIdentifier is deprecated", I gone through the similar questions that are asked in stack overflow but i didn't satisfied. I shown you my coding that i used in the project below

SKPayment *payment=[SKPayment paymentWithProductIdentifier:@"com.mycompany.dmaker.maker1"];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];

Can anyone tell me 1)the alternative for this warning. 2)or tell me whether this project approve in appstore if i use this existing code.

Answer 1

Try using this:

SKProduct *selectedProduct = <#from the products response list#>;
SKPayment *payment = [SKPayment paymentWithProduct:selectedProduct];
[[SKPaymentQueue defaultQueue] addPayment:payment];
