Question

我创建了一个UITableView并设置了所有内容，以便在表格中提取我想要的正确数据。我唯一的问题是，当我点击一个项目时，我希望它打开viewController

我已正确设置故事板ID，所以一切都应该有效，但请看下面的代码，因为有一些明显我错过了：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.
    /*
     <#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
     // ...
     // Pass the selected object to the new view controller.
     [self.navigationController pushViewController:detailViewController animated:YES];

     */

    UIViewController *newTopViewController;


    if (indexPath.section == 0) {

        NSString *identifier = [NSString stringWithFormat:@"%@", [self.section1 objectAtIndex:indexPath.row]];

        newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];

    } else if (indexPath.section == 1) {

        NSString *identifier = [NSString stringWithFormat:@"%@", [self.section2 objectAtIndex:indexPath.row]];

        newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];

    }

    else if (indexPath.section == 2) {

        NSString *identifier = [NSString stringWithFormat:@"%@", [self.section3 objectAtIndex:indexPath.row]];

        newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];

    }





}

如果需要，我可以提供更多信息

Answer 1

使用instantiateViewControllerWithIdentifier创建视图控制器对象。但是您没有呈现创建的视图控制器对象，因此请添加：

[self.navigationController presentViewController:newTopViewController animated:YES completion:nil];

Answer 2

如果标识符正确并且您在故事板中设置了segues，那么您只需调用

即可

[self performSegueWithIdentifier:indentifier sender:nil];

Answer 3

您需要推送yournewTopViewController

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

或以模态方式呈现您的newTopViewController

    [self.navigationController presentViewController:newTopViewController animated:YES completion:nil];

在didSelectRowAtIndexPath方法的末尾。

Answer 4

要回答您的问题，我相信您应该首先导入所有.h文件。然后你可以去

if (indexPath.section == 0) {

   FirstViewController *firstController = [[FirstViewController alloc] init];
   [self presentViewController:firstController animated:YES completion:nil];

}

依旧等等
