我有一个UITableView用户可以从中选择自定义声音。我有 3 个 IAP 非消耗品，我根据index.section用户从中选择的逻辑内置了逻辑。逻辑上的UIToolbarButton更改（用户可以单独IBAction保存选择，但前提是他们“购买”了产品）：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    // Pull identifiers for IAP
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    bool alarmpackpurchased = [defaults boolForKey:@"Alarm_Pack"];
    bool annoyancepackpurchased = [defaults boolForKey:@"Annoyance_Pack"];
    bool serenepackpurchased = [defaults boolForKey:@"Serene_Pack"];

    // Defualt index will always be allowed to save
    if(indexPath.section == 0) {
        savebuybutton.enabled = YES;
        savebuybutton.title = @"Save";
        savebuybutton.tintColor = [UIColor blueColor];
    }
    else {

        if (indexPath.section == 1 && alarmpackpurchased == TRUE) {
            savebuybutton.enabled = YES;
            savebuybutton.title = @"Save";
            savebuybutton.tintColor = [UIColor blueColor];
        }
        else if (indexPath.section == 2 && annoyancepackpurchased == TRUE) {
            savebuybutton.enabled = YES;
            savebuybutton.title = @"Save";
            savebuybutton.tintColor = [UIColor blueColor];
        }
        else if (indexPath.section == 3 && serenepackpurchased == TRUE) {
            savebuybutton.enabled = YES;
            savebuybutton.title = @"Save";
            savebuybutton.tintColor = [UIColor blueColor];
        }

        else {
            savebuybutton.enabled = YES;
            savebuybutton.title = @"Buy Pack";
            savebuybutton.tintColor = [UIColor redColor];
        }
    }
}

这是viewWillAppear:通知观察者的方法：

- (void)viewWillAppear:(BOOL)animated {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(productPurchased:) name:IAPHelperProductPurchasedNotification object:nil];
}

这是我在完成此产品的 IAP 后收到的错误：

您可能没有productPurchased在productPurchased. 还要确保注册通知的 viewController 实现了这个方法。如果方法是在另一个类中定义的，则更改该行以适合您的 className 而不是 self。

 [[NSNotificationCenter defaultCenter] addObserver:yourClassObject selector:@selector(productPurchased:) name:IAPHelperProductPurchasedNotification object:nil];

在viewDidLoad方法中添加观察者而不是viewWillAppear

我认为您没有productPurchased在AlarmSelectViewController.

注意：您可以在某处实施。找到并纠正它。
