ios - UiCollcetionViewCell 特定的 segue 连接 TableView 显示 TableView 内的特定内容

Question

你好，我想问的问题是有没有一种方法可以在 Objective C 中创建这样的代码，它允许我在 UICollectionViewController 中选择一个 UICollectionViewCell 和将它链接到一个 TableView ，该 TableView 根据已选择的 UICollectionViewCell 显示 UICollectionViewCell 特定内容，而无需创建数百个 UITableViewController？

我知道这不是代码，但如果可能的话，这是我希望代码实现的目标:

点击 Collection View 单元格显示表格 View 。

然后在 TableView 上...

如果点击 Collection View 是 dresses 显示 dresses TableView 。

这真的可能吗？

此外，如果可能的话，我希望代码以某种方式将事物组合在一起，因为这将大规模完成我有 106 个 Collection View 单元格需要链接到表格 View ，每个表格 View 至少需要包含 30 个 TableViewCells。

我尝试了你的问题来获取解决方案。最后我成功地得到了解决方案。下面的代码完美运行。

在 View Controller 中

.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
