Table 查看数据通过数组传递

Question

朋友们，我想让table视图数据通过数组相互传递。

如果我们在第一个 table 视图中单击类别食物，它应该在第二个 table 视图中以唯一行显示酒吧餐厅的详细信息选项，我不知道如何在之间传递数据，请帮忙，如果你愿意，我可以提供代码，如果需要，我可以发送屏幕截图。

我需要这样的视图，请尽快帮助。

#import "categoryViewController.h"

@interface categoryViewController ()<UITableViewDelegate,UITableViewDataSource>
{
NSArray *tableData,*thumbNails;
}
@property (weak,nonatomic) IBOutlet UITableView *categoryTable;
@property (weak,nonatomic) NSArray *tabledata;
@end

@implementation categoryViewController

- (void)viewDidLoad {

    tableData = [[NSArray alloc]initWithObjects:@"Food and Drinks",@"Shopping",@"Housing",@"Transportation",@"Vehicle",@"Life and Entertainment",@"Communication & PC",@"Financial Expenses",@"Investment",@"Income",@"Others",nil];

//thumbnails=[[NSArray alloc]initWithObjects:@"Food and Drinks.png"@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png",@"Shopping.png", nil];

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:  (NSInteger)section
{
return tableData.count;
}

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{   //Updated method to go to the next View.
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"Cell"];

    if (cell==nil) {
        cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
    }
    //outdated method.
  //  UITableViewCell *cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];

    cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
    //cell.imageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
    // work on ittttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt.

    return cell;
    }
    /*
    -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
NSIndexPath *index = [self.categoryTable indexPathForSelectedRow];
subcategoryViewController *scVC = [segue destinationViewController];
}
*/
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(IBAction)backBtn:(id)sender{
    [self dismissViewControllerAnimated:YES completion:nil];
}
/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@john 有两种方法可以按照您想要的方式传递数据，1。您可以单独创建变量以导航控制器并在 segue 方法 2 中给它们赋值。或者您可以使用键值传递数据如果您想要比分享您的屏幕截图更详细的信息，您希望如何管理您的数据。
