我创建了一个名为 ViewControll 的页面，即 tableview。我从 url 读取 2 组 NSString 并将其存储在 NSMutableArray 中。（名称：文件和文件夹）并且两个数组都存储一个具有名称的数组：（全部）此 NSMutableArray 显示在根页面（ViewController）中

我有两个页面的名称：（TabelViewController & DetailViewController）TabelViewController 用于文件夹数组，DetailViewController 用于文件数组。

如果该单元格来自文件夹数组，我想何时单击单元格，则转到 TableViewController 页面，否则，如果该单元格来自文件数组，则转到 DetailViewController 页面。

这是我的代码，但不起作用！！！： ViewController.h

@interface ViewController : UITableViewController
{
    NSMutableArray *folder;
    NSMutableArray *file;
    NSMutableArray *all;
    NSInteger folderNumber,fileNumber;
}
@property (nonatomic,strong) IBOutlet UITableView *tables;
@end

    [super viewDidLoad];
    NSString *Number1 = [[NSString alloc]initWithContentsOfURL:[NSURL URLWithString:@"http://192.168.1.101/mamal/filemanager.php?dir=root&filenum"]];
     fileNumber = [Number1 integerValue];

    NSString *Number2 = [[NSString alloc]initWithContentsOfURL:[NSURL URLWithString:@"http://192.168.1.101/mamal/filemanager.php?dir=root&foldernum"]];
     folderNumber = [Number2 integerValue];

-initWithNibName:bundle:是 UIViewController 的指定初始化器。

TableViewController *vc = [[TableViewController alloc] initWithNibName:@"TableViewController" bundle:nil];

对视图控制器使用这种初始化

尝试这个

在单个文件夹和文件数组中搜索所选名称

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
  UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
  if([folder containsObject:[all objectAtIndex:indexPath.row])
    {
       TableViewController *tableVC = [storyboard instantiateViewControllerWithIdentifier:@"TableViewController"]; 
       [self.navigationController pushViewController:tableVC animated:YES]; 
    }
  else
    {
       DetailViewController *detail = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];
       [self.navigationController pushViewController:detail animated:YES]; 
    }
}
