Question

I have created one navigation based application. In that first view show me the list of the drinks and in second view it show me the Details of the Drinks.
All seems ok but while i am navigatting the view at (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath Method, It will show me the error like

terminate called after throwing an instance of ‘NSException’

at line

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

Plese help me, why it happens like that ?

My code for the method is as follow:

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

    DrinkDetailViewController *drinkDetailViewController = [[DrinkDetailViewController alloc] initWithNibName:@"DrinkDetailViewController" bundle:nil];
    //UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:drinkDetailViewController];

    //[self presentModalViewController:drinkDetailViewController animated:YES];

    //[self dismissModalViewControllerAnimated:YES];

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

    [drinkDetailViewController release];

}

While i click on row, it shows me that exception message.
This is project log:

Answer 1

This is the crash regarding that your IBOutlet for View in DrinkDetailViewController is not set in XIB file. Please set Your View in XIB and then try to run the app. This is done using Interface builder..

Happy Coding…
