tableview导航

Question

我遇到了尝试让新的viewcontroller工作的问题。我有UITableView从plist文件加载。第一行将转到detailviewcontroller，但下一行不会出错并且有错误。第二个控制器中的错误DetailViewController2可能无法响应“从文件中获取步骤”。有什么想法吗？

 DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
[detailViewController getStepsFromFile:[files objectAtIndex:indexPath.row]];

// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];

DetailViewController2 *detailViewController2 = [[DetailViewController2 alloc] initWithNibName:@"DetailViewController2" bundle:nil];
[detailViewController2 getStepsFromFile:[files objectAtIndex:indexPath.row]];

// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController2 animated:YES];
[detailViewController2 release];

Answer 1

我使用此代码从tableview导航不同的两个屏幕。

  - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
 {
    if (indexPath.row == 0) 
        {
            DetailViewController *C = [[DetailViewController alloc]init];
            [self.navigationController pushViewController:C animated:NO];
            [c release];

        }
     else
     {

         DetailViewController1 *C = [[DetailViewController1 alloc]init];
        [self.navigationController pushViewController:C animated:NO];
         [C release];

    }

在.h中声明方法-getStepsFromFile，以使其对类的任何实例可见。

编辑： 尝试没有动画的第一个，然后动画第二个，如下：

[self.navigationController pushViewController: detailViewController animated: NO];
[self.navigationController pushViewController: detailViewController2 animated: YES];
