在 TableView 中使用多个详细视图 [英] Using multiple detail views with TableView

问题描述

我正在尝试在我的标签栏应用程序中实现一个表格视图页面.我已经成功制作了一个包含数据的表视图，我希望这能带我进入详细视图.但是，我希望每个单元格都有单独的细节视图，以允许我使用 UI 创建更详细的细节视图.我已经给了 Seque 的唯一 ID 来尝试这样做.

Im trying to implement a table view page within my tabbed bar application. I have successfully made a table view containing data, and I want this to take me to a detail view. However I want separate detail views for each Cell, to allow me to create more detailed detail views using the UI. I have given the Seque's unique IDs to try and do this.

目前我每次按下按钮都会崩溃，将我带到 main.m

Currently it crashed every time I press the button, taking me to main.m

这是我的代码:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    switch (indexPath.row) {
        case 0:
            [self performSegueWithIdentifier:@"showDetail1" sender:self];
            break;
        case 1:
            [self performSegueWithIdentifier:@"showDetail2" sender:self];
            break;
        case 2:
            [self performSegueWithIdentifier:@"showDetail3" sender:self];
            break;
        case 3:
            [self performSegueWithIdentifier:@"showDetail4" sender:self];
            break;
        default:
            break;
     }
}

我得到的例外是:

由于未捕获的异常‘NSGenericException’而终止应用程序，原因:‘找不到segue‘showDetail2’的导航控制器.只有当源控制器由UINavigationController的实例管理时才能使用推送segue."

"Terminating app due to uncaught exception 'NSGenericException', reason: 'Could not find a navigation controller for segue 'showDetail2'. Push segues can only be used when the source controller is managed by an instance of UINavigationController.'"

谢谢！

推荐答案

添加 tableView 的 ViewController 应该是 NavigationController 的一部分.ViewController 只能被推送，如果它是 NavigationController 的一部分.或者尝试使用 Present Segue.

The ViewController where you have added your tableView, should be a part of a NavigationController. A ViewController can only be pushed if it is a part of NavigationController. Else try using Present Segue.

解决方案 1:

让你现在的 ViewController 加入你的 tableView 成为 NavigationController

Make your present ViewController in which you have added your tableView a part of NavigationController

如果您使用的是 StoryBoard，请选择您添加了 tableView 的 ViewController.选择控制器后，选择 Editor\Embed In\Navigation Controller

If you are using StoryBoard, then select your ViewController in which you have added the tableView. With the Controller selected, choose Editor\Embed In\Navigation Controller

解决方案 2:

如果您不想使用Navigation/Push 设计，那么您可以呈现ViewController.为此，您必须使用 Present Segues.

If you do not want to use Navigation/Push design then you can present the ViewController. For that you have to use Present Segues.
