如何避免iphone中的单元格选择错误

Question

嗨，朋友，我的应用程序在单击单元格时崩溃，因为我在这一行 rowToSelect=indexPath;. 但我需要这一行，当我单击 section1 ==row==0 时，我必须传递在 cellbackground 图像上选择的图像的所有行我得到这个错误

'-[__NSArrayM row]: 无法识别的选择器发送到实例 0x4c7080' * 第一次抛出调用栈：(0x37e378bf 0x379831e5 0x37e3aacb 0x37e39945 0x37d94680 0x319921e9 0x319921af 0x5b47 0x3193f9cb 0x3193eaa9 0x3193e233 0x318e2d29 0x37d9622b 0x37430381 0x3742ff99 0x3743411b 0x37433e57 0x3742bd85 0x37e0bb4b 0x37e09d87 0x37e0a0e1 0x37d8d4dd 0x37d8d3a5 0x37b64fcd 0x3190d743 0x2927 0x28dc) 终止 调用抛出异常程序收到信号：“SIGABRT”。数据 格式化程序暂时不可用，将在“继续”后重试。 （找不到dlopen函数，所以无法加载shared 图书馆。）

        UIViewController <SubstitutableDetailViewController> *detailViewController = nil;

        if ([indexPath row] == 0 && [indexPath section] == 0) {
            TodoDetailViewController *newDetailViewController = [[TodoDetailViewController alloc] initWithNibName:@"TodoDetailViewController" bundle:nil];
            detailViewController = newDetailViewController;


        }

        if ([indexPath row] == 0 && [indexPath section] == 1){
            PeopleViewController *newDetailViewController = [[PeopleViewController alloc] initWithNibName:@"PeopleViewController" bundle:nil];

            detailViewController = newDetailViewController;

        }

         if ([indexPath row] == 1 && [indexPath section] == 1){
            DocumentsViewController *newDetailViewController = [[DocumentsViewController alloc] initWithNibName:@"DocumentsViewController" bundle:nil];
            detailViewController = newDetailViewController;
        }

         if ([indexPath row] == 2 && [indexPath section] == 1){
            PlannerViewController *newDetailViewController = [[PlannerViewController alloc] initWithNibName:@"PlannerViewController" bundle:nil];
            detailViewController = newDetailViewController;
        }



         if ([indexPath row] == 0 && [indexPath section] == 2){
            ArchivedPeopleViewController *newDetailViewController = [[ArchivedPeopleViewController alloc] initWithNibName:@"ArchivedPeopleViewController" bundle:nil];
            detailViewController = newDetailViewController;
        }




        // Update the split view controller's view controllers array.
       NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
        splitViewController.viewControllers = viewControllers;


        if (popoverController !=nil) 
        {
            [popoverController dismissPopoverAnimated:YES];
        }
       .
        if (rootPopoverButtonItem != nil) {
            [detailViewController showRootPopoverButtonItem:self.rootPopoverButtonItem];
        }
        [detailViewController release];

    }

把它变成
