问题：如何从一个tableview通过segue跳转到另一个view？

答案：in the storyboard did you use a cell prototype? If so, did you control-drag from the prototype to the destination viewcontroller and create the named segue?

The method you are using requires the segue to be defined completely in the storyboard, meaning the trigger for the segue is tied to the cell prototype.

You can manually trigger a segue using:

[self performSegueWithIdentifier:@"ShowCarDetails" sender:self];

in your:

tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath as an alternative.
