使用RMStore可以大大简化iOS内置付费的开发工作。

获取IAP为购买做准备

NSSet *products = [NSSet setWithArray:@[@"fabulousIdol", @"rootBeer", @"rubberChicken"]];
[[RMStore defaultStore] requestProducts:products success:^(NSArray *products, NSArray *invalidProductIdentifiers) {
    NSLog(@"Products loaded");
} failure:^(NSError *error) {
    NSLog(@"Something went wrong");
}];

购买产品

[[RMStore defaultStore] addPayment:@"waxLips" success:^(SKPaymentTransaction *transaction) {
    NSLog(@"Product purchased");
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"product ID"]; // 将购买信息保存起来
} failure:^(SKPaymentTransaction *transaction, NSError *error) {
    NSLog(@"Something went wrong");
}];

Restore已购

[[RMStore defaultStore] restoreTransactionsOnSuccess:^{
    NSLog(@"Transactions restored");
} failure:^(NSError *error) {
    NSLog(@"Something went wrong");
}];
