I have a custom UICollectionViewCell whose content is also a collection and I would like to use UICollectionView to display its content. Is this possible? How would I accomp
It isn't possible to add a container view to the UICollectionVIew prototype cell in the storyboard, as BrettThePark mentioned.
What you can do is create a separate view controller in the storyboard and add this programatically to the view in the UICollectionViewCell subclass you're using in your UICollectionView. This view controller can off course be a UICollectionViewController.
Example:
-(void)awakeFromNib
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard"
bundle: nil];
UIViewController *controller = [mainStoryboard instantiateViewControllerWithIdentifier:@"MyUIViewController"];
[self addSubview:controller.view];
}
