ios - 暂停 segue 直到 IAP 交易完成

Question

当purchaseButton选择它开始购买 IAP 的过程，这会将用户转到下一个 ViewController .

我需要弄清楚如何让 segue 推迟将用户发送到下一个 ViewController直到 IAP 交易完成。

有什么建议么？将根据需要发布任何额外的代码。谢谢!

转场

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.

    if ([segue.identifier isEqualToString:@"leaguesEdit"]) {

        UIButton *button = (UIButton *)sender;
        MREditLeaguesViewController *levc = (MREditLeaguesViewController *)segue.destinationViewController;
        levc.buttonNumber = (int)button.tag;
        NSLog(@"LEVC #: %d", (int)button.tag);
    }
    else if ([segue.identifier isEqualToString:@"nothing"]) {
        // Nothing
    }
}

segue从 ViewController 连接.和 IBAction它位于:

- (IBAction)purchase:(id)sender {
    [self purchaseProduct:[validProductsInStore objectAtIndex:0]];
    NSLog(@"IBAction Purchase");

    [self performSegueWithIdentifier:@"leaguesEdit" sender:sender];
}

您可以简单地连接 Storyboard中的 segue，但从 View Controller 到 View Controller 。然后，您可以在准备好后以编程方式调用 segue:

[self performSegueWithIdentifier:@"leaguesEdit" sender:nil];
