what is the alternative solution for paymentWithProductIdentifier? - iphone

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];

Answer 2

You can replace paymentWithProductIdentifier: with following codes:
// SKPayment *payment = [SKPayment paymentWithProductIdentifier:productId];
// [[SKPaymentQueue defaultQueue] addPayment:payment];
NSSet *productIdentifiers = [NSSet setWithObject:productId];
self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
self.productsRequest.delegate = self; // your wrapper for IAP or AppDelegate or anything
[self.productsRequest start];
while productsRequest is a retain property.
And implement a SKProductsRequestDelegate method:
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
for (SKProduct *product in response.products) {
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
self.productsRequest = nil;
}

Answer 3

You have 3 options:
suppress this warning with preprocessor definition:
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
SKPayment *payment=[SKPayment paymentWithProductIdentifier:#"com.mycompany.dmaker.maker1"];
#pragma clang diagnostic pop
[[SKPaymentQueue defaultQueue] addPayment:payment];
create SKMutablePayment instead of SKPayment:
SKMutablePayment *payment = [[SKMutablePayment alloc] init];
payment.productIdentifier = #"com.mycompany.dmaker.maker1";
payment.quantity = 1;
[[SKPaymentQueue defaultQueue] addPayment:payment];
use paymentWithProduct: convenience initializer:
SKPayment *payment = [SKPayment paymentWithProduct:<# product that you received in productsRequest:didReceiveResponse: #>];
[[SKPaymentQueue defaultQueue] addPayment:payment];

Answer 4

You could use the following code instead, it does have a little extra that you may already have, but just to make sure
#define kInAppPurchaseId "(your product ID here)"
- (void)makePurchase{
//call this when you would like to begin the purchase
//like when the user taps the "purchase" button
NSLog(#"User requests to make purchase");
if([SKPaymentQueue canMakePayments]){
NSLog(#"User can make payments");
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kInAppPurchaseId]];
productsRequest.delegate = self;
[productsRequest start];
}
else{
//the user is not allowed to make payments
NSLog(#"User cannot make payments due to parental controls");
}
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
validProduct = [response.products objectAtIndex:0];
NSLog(#"Products Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(#"No products available");
}
}
- (IBAction)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
I use this code in one off my applications, so it should work.
