ios - 使用 popToViewController 返回到黑屏的特定 View Controller 时出现问题

Question

我正在使用像这样的基本操作来推送到 View 。

UIStoryboard *storyboard = self.navigationController.storyboard;

MenuViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"menuViewController"];

[self.navigationController pushViewController:viewController animated:YES];

一些我可以简单使用的地方:

[self.navigationController popViewControllerAnimated:YES];

但在一些地方我想弹出一个特定的 View Controller 。我尝试过的是:

UIStoryboard *storyboard = self.navigationController.storyboard;

RecordMenuViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"recordMenuViewController"];

[self.navigationController popToViewController:viewController animated:YES];

但它只是进入黑屏，就像 View 不在堆栈中一样。我在这里缺少什么？

Answer 1

如果您想使用导航堆栈弹出到特定的 View Controller ，请执行以下操作:

NSArray* vcs = self.navigationController.viewControllers;
UIViewController* target = [vcs objectAtIndex:([vcs count] - 1) - numVCsToGoBack];
[self.navigationController popToViewController:target];
