How to use purchases:shouldPurchasePromoProduct:defermentBlock: in Objective-C?

Hey @toco! 👋

In Objective-C, you’ll want to be sure your RCPurchases delegate class conforms to RCPurchasesDelegate. If you are using AppDelegate as your RCPurchases delegate, it might look like this in your AppDelegate.h file:

1#import "RCPurchases.h"
2
3@interface AppDelegate : UIResponder <UIApplicationDelegate, RCPurchasesDelegate>
4

In AppDelegate.m, your shouldPurchasePromoProduct method might look like this:

1- (void)purchases:(RCPurchases *)purchases shouldPurchasePromoProduct:(SKProduct *)product defermentBlock:(RCDeferredPromotionalPurchaseBlock)makeDeferredPurchase {
2
3    makeDeferredPurchase(^(SKPaymentTransaction * transaction, RCPurchaserInfo *info, NSError *error, BOOL userCancelled) {
4        //...
5    });
6}
