我在导航控制器中有两个表视图控制器。Cloth 表是主视图,当我单击其中一个单元格时,转到另一个提供详细信息的视图控制器,当我选择我想要的选项并返回导航按钮的返回时,我会丢失信息。如何将值带到主视图?
这是我的代码:主视图 - AddClothViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([[list objectAtIndex:indexPath.row] isEqual:@"Categorias"] )
{
    CategoriesViewController *DVC = [[CategoriesViewController alloc]    initWithNibName:@"CategoriesViewController" bundle:nil];
    [self.navigationController pushViewController:DVC animated:YES];
}
}
这是我的代码:类别 ViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Set the checkmark accessory for the selected row.
[[tableView cellForRowAtIndexPath:indexPath]  setAccessoryType:UITableViewCellAccessoryCheckmark];
// This is my main View Controller when i declare a variable category and I try to access   from 
 //here    
  AddClothViewController *DVC = [[AddClothViewController alloc]  initWithNibName:@"AddClothViewController" bundle:nil];
  DVC.clothNew.categoria = [list objectAtIndex:indexPath.row ];   
}
