indexPath更改爲UITableViewController後爲零

Question

由於我將視圖更改爲Storyboard中的UITableViewController，因此我的indexPath爲零。有人能發現錯誤嗎？我使用segues。我已將TableViewController的虛擬單元連接到新的TableViewController。兩者都是一個UINavigationController

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

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{ 
    // Assume self.view is the table view 
    NSIndexPath *path = [self.tableView indexPathForSelectedRow]; 
    Country *country = (Country *)[fetchedResultsController objectAtIndexPath:path]; 

    if ([segue.identifier isEqualToString:@"selectCountry"]) 
    { 
     CaveTableViewController *ctvc = [segue destinationViewController]; 
     ctvc.country = country; 
     ctvc.navigationItem.title = country.country; 
    } 

    [self.tableView deselectRowAtIndexPath:path animated:YES]; 
} 

Answer 1

嘗試改變內推：

NSIndexPath *path = [self.tableView indexPathForSelectedRow]; 

要：

NSIndexPath *path = [self.tableView indexPathForCell:sender];
