How to find indexPath for tapped button in tableView Using Seque

Question

I have a UITableView using prototype cell.

The cells have a UIButton that show a UIViewController (Modal) using Segue

Answer 1

First make a global int variable selecteIndex;

In your cell, give your button tag similar to cell's indexPath.row value

E.g. btn.tag = indexPath.row;

The assing & call action on click of that button

[btn addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];

-(void)buttonClicked:(id)sender
{
    UIButton *btn = (UIButton*)sender;
    selectedIndex = btn.tag;
    [self performSegueWithIdentifier:@"segueName" sender:self];
}

Then at end of your view write this function

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"segueName"]) {
        viewController *dvc = (viewController *)[segue destinationViewController];
        [dvc setSelected:selectedIndex];
    };
}
