    // and each section will be separated from the other ones.

    [self.navigationController pushViewController:controller animated:YES];
    [controller release];
} 

compile with error..had imported all the files..wat went wrong?

Answer 1

Is the controller being init'd properly? Did you check if its null or something's wrong? Put a breakpoint on it and check it out:

 DetailViewController *controller = [[DetailViewController alloc]

Answer 2

Try using:

[controller setTitle:[[dao libraryItemAtIndex:indexPath.row] valueForKey:@"Description"];

Answer 3

Actually, I'm guessing that the controller object (of class DetailViewController) doesn't actually have the property "title" as is needed for the "dot-syntax" to work.

Does DetailViewController properly inherit from UIViewController?

Answer 4

nop..it wasnt inherit from uiview..and the above code isn't working either..gosh!

Answer 5

// compile with error..had imported all the files..wat went wrong?
