Answer 1

This line raise the exception :

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

The line above initialise a view controller with a nib file(.xib)

As you say in your comment, you are using storyboard so you should use UIStoryboard Class

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

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

Now, to get the identifier of your view controller :

1. Open your storyboard
2. Click on your view controller (Detail view controller here)
3. On the right side : Utilities, click on show the identity inspector (third button)
4. In the storyboard ID field, put the identifier (DetailViewController identifier for example)

Edit :

I think that the name of your storyboard is wrong. In your project you have a file called Main.storyboard or somethingElse.storyboard, so you should replace storyboard in this line :

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"storyboard" bundle:nil]; by Main or somethingElse without the .storyboard extension

Then you replace DetailViewController identifier in this line UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController identifier"]; by the identifier of your view controller (story in your screenshot)

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];

}
