Detail View Controller from Table View Controller WITHOUT Storyboard? - ios

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 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 2

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 3

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 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];
}
