Dynamic cell height in UITableView with variable number of subviews

I was wondering if someone could help me in this feature for dynamic cells for UITablewView.

I need to add subviews to a cell depends on some context. So the cell will grows if a have more than one of this subviews:

I'd like to know how can I add this subviews programatically and how to make the cells grows dynamic using constraints?
