Question

我正在使用此功能，但它不起作用。我正在使用StoryBoard和xcode 4.3。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

     pushnavViewController *detailViewController = [[pushnavViewController alloc] initWithNibName:@"pushnavViewController" bundle:nil];

    detailViewController.pushh.text = [listt objectAtIndex:indexPath.row];
     // Pass the selected object to the new view controller.
     [self.navigationController pushViewController:detailViewController animated:YES];

}

Answer 1

这是答案：

当您使用故事板时，您必须使用

pushnavViewController *detailViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"pushnavViewController"];

不是

     pushnavViewController *detailViewController = [[pushnavViewController alloc] initWithNibName:@"pushnavViewController" bundle:nil];

另外，不要忘记从storyborad设置标识符。

Answer 2

我以为我会从评论中拿出这个，然后尝试解决方案。对不起，这不是一个直接的解决方案，而是更多的建议......

也许最好的办法是（如果您使用Xcode 4.x）创建一个新项目，选择“Master-Detail Application”模板。查看AppDelegate类，看看如何将MasterViewController添加为UINavigationController的根视图控制器。了解其工作原理并尝试将其应用于您的情况。

另外，请查看UINavigationController的类引用。

Answer 3

1-创建故事板标识符：pushnavViewController 单击ViewController，选择选项卡标识检查器==＆gt;故事板ID：pushnavViewController

2-使用Storyboard标识符启动UIViewController

 UIStoryboard *mainStoryboard = self.storyboard;
    UIViewController *mainViewController = [mainStoryboard instantiateViewControllerWithIdentifier:@"pushnavViewController"];

3-推送到另一个ViewController [self.navigationController pushViewController：mainViewController animated：YES];

以下是代码：

-(void) openABCPage
{
    UIStoryboard *mainStoryboard = self.storyboard;
    UIViewController *mainViewController = [mainStoryboard instantiateViewControllerWithIdentifier:@"pushnavViewController"];
    [self.navigationController pushViewController:mainViewController animated:YES];

}

通过自定义UITableViewCell推送到新的UIViewController
