Perform segue with accessoryButton - xcode

Question

I am doing master + detail pages. I have successfully made tapping the cell rows in the master page jump to detail page, using the code below
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"MasterToDetail" sender:indexPath];
}
However becuase my master page cell rows also have accessory buttons, i need to make these buttons able to jump to the detail page too through tapping. So i implemented code
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"MasterToDetail" sender:self];
}
Howver the details dispalyed is not correct. It always shows the first detail data in the datalist. I changed sender:self to sender:indexPath also no working.
I used stackoverflow answers from here and here. I am a beginner, so some concepts still no clear sorry.
Edited

Answer 1

This is due to following statement
SearchDataDetail *bug = [self.bugs objectAtIndex:self.tableView.indexPathForSelectedRow.row];
In this self.tableView.indexPathForSelectedRow.row will work only for only for row selection
not for accessoryButton tap.
You can solve it by two easy way
Declare a variable in .h file to store indexPath and use it to pass selected indexPath.
Pass indexPath in sender
All the best..
