Question

Problem: On selection of a particular uitableviewcell, a new DetailViewController should be opened. I have written the code in didSelectRowAtIndexPath but when I click on the cell it is showing me a runtime error.

I have tried calling with [self.navigationController presentModalViewController:jacket animated:YES ]; but when I do my view controller is not getting opened.

Another method I tried is by [self.navigationController performSegueWithIdentifier:@"JacketDetails" sender:self ];.

I have Specified Identifier in the segued has “JacketDetails” in the inspector but here I am getting a run yime error. I have Hooked Segue from UITABLEVIEWCELL to VIEWCONTROLLER.

When I click on the row JacketDetailViewController Should be open. I have Created Class JacketDetailViewController and for New ViewController I have set the class for this in the inspector.

I don’t know why it is showing no segue , I have given the identifier in the inspector and properly hooked from tableviewcell to new view controller.

In JacketDetailViewController I want to display a list of Jackets. Presently it is blank ViewController.

My code is below. Would you please suggest a solution? I am a self-teaching beginner in this field. I might have made some minor mistakes. I have Googled my problem and tried to solve it but I have been stuck here for a few days.

TshirtDetailViewController.m

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.

    [tableView deselectRowAtIndexPath:indexPath animated:YES ];

    JacketDetailController *jacket =[[JacketDetailController alloc]init];

    NSInteger index =indexPath.row;

    NSLog(@"Row:%d",index);


    NSString *titleString = [[NSString alloc] initWithFormat:[jackets objectAtIndex:indexPath.row]];


    NSLog(@"%@",titleString);
    jacket.title=titleString;


    // ...
    // Pass the selected object to the new view controller.

    [self.navigationController performSegueWithIdentifier:@"JacketDetails" sender:self ];


  //  [self.navigationController presentModalViewController:jacket animated:YES ];

}

Try to open view with these lines:

    YoutubeViewController *objYoutubeViewController = [[YoutubeViewController alloc]initWithNibName:@"YoutubeViewController" bundle:[NSBundle mainBundle]];
    [self.navigationController pushViewController:objYoutubeViewController animated:YES];
    [objYoutubeViewController release];

In place of YoutubeViewController give your view controller class name & change these lines

According to you & check.Ok if you using storyboard then try like below:

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
 bookmarkViewController *myVC = (bookmarkViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:@"bookmarkViewController"]
[self presentModalViewController:myVC animated:YES];

in place of bookmarkViewController give your controller name & check. in drag & drop view

controller in main storyboard give right class name like below images:

in place of my bookmarkViewController name give your view controller name that you want to open.
