Question

我创建一个名为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），两个数组都存储一个名称为:( all）的NSMutableArray显示在根页面（ViewController）

我有另外两个名字：（TabelViewController＆amp; DetailViewController），TabelViewController用于文件夹数组，DetailViewController用于文件数组。

我希望何时单击单元格，如果该单元格来自文件夹数组，请转到TableViewController页面，否则，如果该单元格来自文件数组，请转到DetailViewController页面。

这是我的代码，但不工作!!!：的 ViewController.h

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

ViewController.m

    [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];

    NSLog(@"file: %d & folder: %d",fileNumber,folderNumber);

    for (int i=0; i < folderNumber; i++)
    {
        NSString *folderName = [[NSString alloc]initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://192.168.1.101/mamal/filemanager.php?dir=root&folder=%d&name",i]]];
        if (!folder)
        {
            folder = [NSMutableArray array];
        }
        [folder addObject:folderName];
    }

    for (int j=0; j < fileNumber; j++)

        }
        [file addObject:fileName];
    }

Answer 1

-initWithNibName:bundle:是UIViewController的指定初始值设定项。

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

对视图控制器使用此类初始化

Answer 2

试试这个

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]; 
    }
}
