无需情节提要的表视图控制器中的Detail View Controller？

Question

I have a tableview in a controller that shows receipts and their image, date created, etc.
I made it so when the user taps a cell, it goes to DetailViewController . Using this code:

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

{
    ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];
    [self.navigationController pushViewController:controller animated:YES];
}

I'd like to pass the image, date, category, etc, to my new view in a UIImageView , textView , etc.
This is the code for my Table in the first controller:

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"Cell"];
    }

    cell.selectionStyle = UITableViewCellSelectionStyleGray;
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    Receipt *receipt = [self.receiptsArray objectAtIndex:indexPath.row];

    ReceiptCategory *category = receipt.relationshipToCategory;
    ReceiptImage *image = receipt.relationshipToImage;

    cell.textLabel.text = category.receiptCategory;
    cell.detailTextLabel.text = receipt.date.description;

    if(self.imageCache.count <= indexPath.row) {
        [self.imageCache addObject:[UIImage imageWithData:image.data]];
    }

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
    imageView.image = [self.imageCache objectAtIndex:indexPath.row];

    cell.imageView.image = imageView.image;

    return cell;
}

How do I pass this data? I have searched around for two days now and all solutions include a storyboard, which I am not using.

Answer 1

You should just use Table View Delegate Method

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

There you can retrieve the selected receipt and pass the data to the detail view like that:

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

{
    ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];
    Receipt *selectedReceipt = [self.receiptsArray objectAtIndex:indexPath.row];
    controller.receipt = selectedReceipt;
    [self.navigationController pushViewController:controller animated:YES];
}

Answer 2

You can create a custom class for your detailed view controller and create an object of the same when the user clicks on any cell. Something like this

DetailViewControllerClass *newObject = [[DetailViewControllerClass alloc] init];
newObject.data1 = dataToBeSent ; //assign data 

Answer 3

You should get reference to your receipt in didSelectRowAtIndexPath: and pass it to ReceiptDetailViewController. I assume you have property to accept the data in ReceiptDetailViewController:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Get reference to receipt
    Receipt *receipt = [self.receiptsArray objectAtIndex:indexPath.row];

    ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];

    // Pass data to controller
    controller.receipt = receipt;
    [self.navigationController pushViewController:controller animated:YES];
}

It this example you should create property in ReceiptDetailViewController.h file:

@property(nonatomic, strong) Receipt *receipt;

Now you can use it in your ReceiptDetailViewController object.

Answer 4

You should make an object of Receipt in ReceiptDetailViewController and make the property nonatomic and strong Than in tour view controller Write this

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Receipt *receipt = [self.receiptsArray objectAtIndex:indexPath.row];

 ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];
controller.objReceipt= receipt;
    [self.navigationController pushViewController:controller animated:YES];

}
