如何获取performSegueWithIdentifier中传递的数据

Question

这可能需要两秒钟才能回答,但我的搜索技巧并没有让我在这个问题上走得太远.我正在执行一个赛格但我不确定如何抓住目的地的身份证.这是我在tableview控制器上的代码.

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath: NSIndexPath *)indexPath{
    NSLog(@"reaching accessoryButtonTappedForRowWithIndexPath:");
    [self performSegueWithIdentifier:@"leads_calls_to_detail" sender:[[self.leads_calls objectAtIndex:indexPath.row] objectForKey:@"ID"]];
}

我必须在目标视图控制器上创建什么才能获取我试图传递的ID,或者我正在执行我的segue与我正在尝试的内容不兼容的方式？

你应该只将值传递给destinationViewController内部prepareForSegue:并self作为发送者传递..尝试使用类似的东西:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([[segue identifier] isEqualToString:@"leads_calls_to_detail"])
    {
       YourViewController *controller=(YourViewController *)segue.destinationViewController;
       NSIndexPath *path = [self.tableView indexPathForSelectedRow];
      //Or rather just save the indexPath in a property in your currentViewController when you get the accessoryButtonTappedForRowAtIndexPath callback, and use it here
       controller.yourPropertyToSet = [self.leads_calls objectAtIndex:path.row];
    }
}

而且根据Rob Mayoff的说法,你可以通过使用以下内容获取附件被点击的行的索引路径:

NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];//where sender is the sender passed in from prepareForSegue:
