iphone - 如何使用 Storyboard从 Masterview 推送到详细 View ？

Question

我试图在 Storyboard中推送到详细 View ，但没有用。

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"drinkList"])
    {
        NSIndexPath *myIndexPath = [self.drinksCatTable indexPathForSelectedRow];

        if (myIndexPath.row ==0) //if selected is row 1 
        {
            selectedDrinkCat  =[segue destinationViewController];
            Drinks *drinkList = [aDelegate.categoryArray objectAtIndex:0];//forward all drinks to drinksList
            selectedDrinkCat.drinkList = drinkList;//point drinkList to the next view drinkList
            selectedDrinkCat.allDrinkStr = @"All";//all drinks selected 
                 NSLog(@"aaa");
        }
        else 
        {
            Drinks *drinkList = [aDelegate.categoryArray objectAtIndex:(myIndexPath.row)-1];//we have to minus 1 as the row had en extra "All" row which is not in the database
            selectedDrinkCat.drinkList = drinkList; 
            selectedDrinkCat.allDrinkStr =@"cat";
            NSLog(@"1111");

        }
    }
}

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

    [self performSegueWithIdentifier:@"drinkList" sender:self];
    NSLog(@"called did select");   

}

你不应该将 selectedDrinkCat 声明为 destinationViewController 类的 viewcontroller 吗？

类似于:

desmondViewController *selectedDrinkCat=(desmondViewController *)[segue destinationViewController];
