ios - 无法识别的选择器发送到应用内购买产品的实例错误

Question

我有一个 UITableView，用户可以从中选择自定义声音。我有 3 个用于 IAP 的非消耗品，我有基于用户从中选择的 index.section 内置的逻辑。 UIToolbarButton 的逻辑改变(有一个单独的 IBAction，用户可以在其中保存选择，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];
        }
    }
}

下面是带有通知观察器的 viewWillAppear: 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:

Answer 1

我认为您没有在 AlarmSelectViewController 中实现 productPurchased 方法。

注意:您可以在某处实现。找出并改正。
