Implement UICollectionView in a UICollectionViewCell

Question

I want to have a UICollectionView where the cells are also UICollectionView s. Is this possible and if so, could someone give me a guide on how to start this? I already have my main UICollectionView , but I'm having trouble implementing another UICollectionView in its UICollectionViewCell .

Answer 1

I did something similar some time ago. Inside your cellForItemAtIndexPath: of your parent CollectionView you have to do something like below. I havent tested this so you might have to add in some code:

ChildCollectionViewController * cv = //Initialize your secondCVController here
  if (!cv) {
    cv = [self.storyboard instantiateViewControllerWithIdentifier:@"collectionViewID”]; //set your class’s storyboard ID before doing this

    cv.view.frame = cell.contentView.bounds;
    [self addChildViewController:cv];
    [cell.contentView addSubview:cv.view];
    [cv didMoveToParentViewController:self];
}
 //Some code here for cell contents

return cell;
}
