How to get indexpath in prepareForSegue

Question

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


        

Answer 1

Like this

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(UITableViewCell *)sender {
    FTGDetailVC *detailVC = (id)segue.destinationViewController;
    NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];

    FTGNote *note = self.notes[indexPath.row];
    [detailVC updateWithNote:note];
}

Answer 2

Swift 3.0 / iOS 10

tableView.indexPathForSelectedRow was introduced in iOS 9

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if let indexPath = tableView.indexPathForSelectedRow{
        let selectedRow = indexPath.row
        let detailVC = segue.destination as! ParkDetailTableVC
        detailVC.park = self.parksArray[selectedRow]
    }
}

sorry, i don't understand what you want to do. it's possible get the indexPath.row through this method of UITAbleViewDelegate that it's called when you tap the cell of your tableView:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{     
    self.myVariable = indexPath.row
}

and then you can access to this value in the prepareForSegue in this way:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    //do something with self.myVariable
}

I hope i helped you.

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];
       }
   }
