CollectionView内部的iOS TableView有时显示不正确的数据

Question

I have a collectionView where I show a list of comments in a tableView. I see that the tableView data is not the correct one when the collectionView is scrolled.

I tried to remedy that using prepareForReuse() which did not work. Here is my code :

override func prepareForReuse() {
        super.prepareForReuse()
        imageView.image = UIImage()
        commentsTableView = UITableView()
    }

I would appreciate if someone can suggest a solution for this.

Thanks.

Answer 1

Assign all your properties to nil.

override func prepareForReuse() {

        imageView.image = nil
        commentsTableView = nil
        super.prepareForReuse()
    }

But make sure that your properties is optional.
