How to get indexpath in prepareForSegue

Question

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
    {
    if ([segue.identifier isEqualToString:@\"Action\"])
    {
        NSIndexPath *indexP         


        

Answer 1

Two cases:

1. Segue connected from the viewController

   Call segue from your didSelectRowAtIndexPath method, pass indexPath as sender

   -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
   {
       [self performSegueWithIdentifier:@"Action" sender:indexPath];
   }
   

   Then you can get indexPath as sender in prepareForSegue:sender: method

   - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
   {
       if ([segue.identifier isEqualToString:@"Action"])
       {
           NSIndexPath *indexPath = (NSIndexPath *)sender;
           SecondViewController *destViewController = segue.destinationViewController;
           destViewController.getString = [getArray objectAtIndex:indexPath.row];
       }
   }
   

2. segue connected from the cell

   No need to implement didSelectRowAtIndexPath method and performSegueWithIdentifier:.You can directly get sender as UITableviewCell in prepareForSegue:sender: method.

   - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
   {
       if ([segue.identifier isEqualToString:@"Action"])
       {
           NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];
           SecondViewController *destViewController = segue.destinationViewController;
           destViewController.getString = [getArray objectAtIndex:indexPath.row];
       }
   }
