Using multiple detail views with TableView

Question:

Im trying to implement a table view page within my tabbed bar application. I have successfully made a table view containing data, and I want this to take me to a detail view. However I want separate detail views for each Cell, to allow me to create more detailed detail views using the UI. I have given the Seque's unique IDs to try and do this.

Currently it crashed every time I press the button, taking me to main.m

Here is the code I have:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.row) { case 0: [self performSegueWithIdentifier:@"showDetail1" sender:self]; break; case 1: [self performSegueWithIdentifier:@"showDetail2" sender:self]; break; case 2: [self performSegueWithIdentifier:@"showDetail3" sender:self]; break; case 3: [self performSegueWithIdentifier:@"showDetail4" sender:self]; break; default: break; } }

The exception I get is:

"Terminating app due to uncaught exception 'NSGenericException', reason: 'Could not find a navigation controller for segue 'showDetail2'. Push segues can only be used when the source controller is managed by an instance of UINavigationController.'"

Thanks!

Answer1:

The ViewController where you have added your tableView, should be a part of a NavigationController. A ViewController can only be pushed if it is a part of NavigationController. Else try using Present Segue.

<strong>Solution 1:</strong>

Make your present ViewController in which you have added your tableView a part of NavigationController

If you are using StoryBoard, then select your ViewController in which you have added the tableView. With the Controller selected, choose <strong>Editor\Embed In\Navigation Controller</strong>

<strong>Solution 2:</strong>

If you do not want to use Navigation/Push design then you can present the ViewController. For that you have to use Present Segues.
