presentViewController不能像我一样工作(presentViewController not working as I'd like)

presentViewController不能像我一样工作(presentViewController not working as I'd like)

我有我的presentViewController代码设置如下：

ProductViewController *vc = [[ProductViewController alloc] init]; [self presentViewController:vc animated:YES completion:nil];

它确实呈现了vc控制器，但我无法点击它，它就像一个冻结的屏幕。 是因为还有一个观点吗？ 或者我不应该使用alloc] init ？

ProductViewController是一个现有的视图控制器（它实际上是根视图控制器），所以基本上我只想让presentViewController返回到根视图控制器。

编辑：

我有一个ShippingViewController ，用户输入名称/运输详细信息。

然后他们点击“Checkout”按钮，显示PaymentViewController （其中有一个导航栏，所有其他View Controller都没有）。 在PaymentViewController ，用户输入他们的信用卡详细信息并点击“付款”按钮。

如果付款成功，我希望展示ProductViewController （初始/根视图控制器）。 目前，如果我只是调用dismissViewController ，它会显示ShippingViewController 。

I have my presentViewController code set up like this:

ProductViewController *vc = [[ProductViewController alloc] init]; [self presentViewController:vc animated:YES completion:nil];

It indeed presents the vc controller, but I'm unable to tap anything on it, it's like a frozen screen. Is it because there is still a view on top of it? Or I shouldn't be using alloc] init?

ProductViewController is an existing view controller (it's actually the root view controller), so basically I'd just like the presentViewController to just go back to the root view controller.

Edit:

I have a ShippingViewController where the user enters name/shipping details.

Then they tap on "Checkout" button that presents the PaymentViewController (which has a navigation bar, all other View Controllers don't). On the PaymentViewController, the user enters their credit card details and tap the "Pay" button.

If the payment is successful, I wish for ProductViewController (the initial/root view controller) to be presented. Currently if I am just calling dismissViewController, it presents ShippingViewController.

最满意答案

这似乎解决了我的问题：

NSString *storyboardName = @"Main"; UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil]; UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"id"]; [self presentViewController:vc animated:YES completion:nil];

This seemed to take care of my problem:

NSString *storyboardName = @"Main"; UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil]; UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"id"]; [self presentViewController:vc animated:YES completion:nil];
