Embedding a UITextView Inside a UITableViewCell for Custom Cell Behavior
Embedding a UITextView Inside a UITableViewCell In this article, we will explore how to embed a UITextView inside a UITableViewCell. This can be a useful technique when you want to display a text view within a table view cell without having to create separate files for the cell. Requirements and Background To achieve this, you will need to create a custom UITableViewCell subclass that contains a UITextView instance. The UIView hierarchy is used here because the UITableViewCell class does not allow direct subviews of other views; instead, it uses a contentView property.
