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 :
Open your storyboard
Click on your view controller (Detail view controller here)
On the right side : Utilities, click on show the identity inspector (third button)
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];
}
