UiCollcetionViewCell specific segue to connect TableView show specific content within TableView

Question

Hi there the question i would like to ask is there a way of creating such code in Objective C that will allow me to select a single UICollectionViewCell within a UICollectionViewController and link it to a table view that shows UICollectionViewCell specific content based upon what UICollectionViewCell has been selected without creating hundreds of UITableViewControllers?

A know this is not code but this is what i want the code to achieve if it is possible:

on click of collection view cell dresses show table view.

then on the table view...

if collection view clicked was dresses display dresses table view.

surely this is possible?

Also if possible i would like the code to somehow group things togethers as this will be done on a large scale i have 106 collection view cells that need linking to table views of which need to contain a minimum of 30 TableViewCells each.

I tried your question for getting solution.Finally I successfully got the solution.Below code works perfectly.

In ViewController

.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UICollectionViewDataSource,UICollectionViewDelegate>

@property (strong, nonatomic) IBOutlet UICollectionView *collectionViewSelection;

@end

.m

#import "ViewController.h"
#import "CustomCollectionViewCell.h"
#import "DetailViewController.h"

@interface ViewController ()
{
   NSMutableArray *arrayCollectionView;
   NSMutableArray *imgArray;
   NSMutableArray *lblArray;
}
@end

@implementation ViewController

@synthesize collectionViewSelection;

- (void)viewDidLoad {
 [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
 imgArray = [NSMutableArray arrayWithObjects:
            [UIImage imageNamed:@"casual.png"],
            [UIImage imageNamed:@"checked.png"],
            [UIImage imageNamed:@"collar.png"],
            [UIImage imageNamed:@"formal.png"],
            [UIImage imageNamed:@"jean.png"],
            [UIImage imageNamed:@"neck.png"],
            [UIImage imageNamed:@"pant.png"],nil];

 lblArray = [NSMutableArray arrayWithObjects:@"casual",@"checked",@"collar",@"formal",@"jean",@"neck",@"pant", nil];
 UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
 flowLayout.scrollDirection =  UICollectionViewScrollDirectionVertical;
 UINib *cellNib = [UINib nibWithNibName:@"CustomCollectionViewCell" bundle:nil];
 [collectionViewSelection registerNib:cellNib forCellWithReuseIdentifier:@"customCollectionCell"];
}

- (void)didReceiveMemoryWarning {
 [super didReceiveMemoryWarning];
 // Dispose of any resources that can be recreated.
}


- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
   return [lblArray count];
}


 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
   static NSString *cellIdentifier = @"customCollectionCell";
   CustomCollectionViewCell *cell = (CustomCollectionViewCell *)[collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
   NSLog(@"The current indexPath row is - %ld",(long)indexPath.row);
   cell.img_Collection.image = [imgArray objectAtIndex:indexPath.row];
   cell.label_Collection.text = [lblArray objectAtIndex:indexPath.row];
   cell.tag = indexPath.row;

   return cell;
}

 - (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath 
{
  return CGSizeMake(260, 176);
}

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
   NSLog(@"The touched index path os collection cell item row is - %ld",(long)indexPath.row);
   DetailViewController *detailsVC = [[DetailViewController alloc]initWithNibName:@"DetailViewController" bundle:nil];
   detailsVC.stringLabeldata = [lblArray objectAtIndex:indexPath.row];
   detailsVC.imageData = [imgArray objectAtIndex:indexPath.row];
   [self.navigationController pushViewController:detailsVC animated:YES];
}
@end

DetailViewController

.h

#import <UIKit/UIKit.h>

@interface DetailViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
@property (strong, nonatomic) IBOutlet UITableView *tableViewDressesData;
@property (strong, nonatomic) UIImage *imageData;
@property (strong, nonatomic) NSString *stringLabeldata;

- (IBAction)actionBack:(id)sender;

@end

.m

 #import "DetailViewController.h"
 #import "CustomTableViewCell.h"

   [tableViewDressesData reloadData];
