ios - Segue 始终不传递行的正确索引路径第 0 节

Question

我使用的是分段 tableView。如果我单击 tableview，它总是将索引路径 0 传递给详细 View Controller 。如果我单击第二行，但它的 indexpath pass 总是传递 0。

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    if ([segue.identifier isEqualToString:@"toNext"]) {
    detailTableViewController *detailVC = [segue destinationViewController];
    [detailVC setkMessageDict:(NSDictionary*)[nArray objectAtIndex:[self.mytableView indexPathForSelectedRow].section]];
}

代码有什么问题？

Answer 1

您需要在序列中创建 index-path 对象，例如:-

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    [self performSegueWithIdentifier:@"toNext" sender:indexPath];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

    NSIndexPath *indexPath = [self.tableview indexPathForSelectedRow];
    NSLog(@" indexPath row %d",indexPath.row);
    NSLog(@" indexPath row %d",indexPath.section);
    detailTableViewController *detailVC = [segue destinationViewController];
    [detailVC setJobDetailDict:(NSDictionary*)[nArray objectAtIndex:indexPath.row];
