使用故事板的 DidSelectRowAtIndexPath [英] DidSelectRowAtIndexPath using a story Board

问题描述

在我的应用程序中，我使用以下 didSelectRowAtIndexPath 方法转到 viewController，但我在故事板中工作，并且抛出异常告诉我找不到 nib 文件.我应该如何更改方法以无异常地打开新的viewController?:

In my app I am using the following didSelectRowAtIndexPath method to go to a viewController, but I am working within an story Board, and an exception is thrown telling me that the nib file is not found. How should I change the method to open the new viewController without exceptions?:

//link to the next view

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    EmpresasTableViewController *detailViewController = [[EmpresasTableViewController alloc] initWithNibName:@"EmpresasTableViewController" bundle:nil];
    detailViewController.title =[[categorias objectAtIndex:indexPath.row]objectForKey:@"idCategoria"];
    detailViewController.categoriaDescription = [categorias objectAtIndex:indexPath.row];
    [self.navigationController pushViewController:detailViewController animated:YES];
}

推荐答案

你必须在你的故事板中为你的 ViewController 创建一个标识符(例如detailViewController)，然后像这样实例化你的 EmpresasTableViewController

you have to make an identifier (detailViewController for example)for you ViewController in your storyboard and then instantiate like this your EmpresasTableViewController

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