StoryBoard

Answer 1

此行引发异常：

DetailViewController *temp =[[DetailViewController alloc]initWithNibName:@"DeatailViewController" bundle:[NSBundle mainBundle]];

上面的行使用nib文件（.xib）初始化视图控制器

正如您在评论中所说，您使用的是故事板，因此您应该使用UIStoryboard Class

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MyStoryboard" bundle:nil];

UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController identifier"];

现在，要获取视图控制器的标识符：

打开故事板
点击您的视图控制器（此处为详细视图控制器）
在右侧：实用工具，点击显示身份检查员（第三个按钮）
在storyboard ID字段中，输入标识符（例如DetailViewController标识符）

修改：

我认为你的故事板的名称是错误的。在您的项目中，您有一个名为Main.storyboard或somethingElse.storyboard的文件，因此您应该在此行中替换 storyboard ：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"storyboard" bundle:nil]; 主要或 somethingElse 没有.storyboard扩展程序

然后用视图控制器的标识符替换此行UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController identifier"];中的 DetailViewController标识符（屏幕截图中的故事）

Answer 2

DetailViewController

@property(nonatomic,retain)NSString *myurl;



- (void)viewDidLoad
{
    [super viewDidLoad];
    NSURL *url= [NSURL URLWithString:myurl];
    NSURLRequest * requestURL= [NSURLRequest requestWithURL:url];
    [info loadRequest:requestURL];

}


Essentialinfocontroller

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

if(indexPath.row==0){ //what ever you want row 


     DetailViewController *temp =[[DetailViewController alloc]initWithNibName:@"DeatailViewController" bundle:nil];

     //or [[DetailViewController alloc]init];


     temp.myurl = @"http://www.google.lk";

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

}


}

例外：无法在捆绑中加载NIB
