iOS Swift - Export Data from Custom Table View Cells on Exit/Save
<p>I have a UITableView with 5 custom UITableViewCells. In the custom UITableViewCells I have IBOutlets for my UI-elements (UILabel, UITextField). I cannot create IBOutlets for the UI-elements in my view controller because they are already linked to my custom UITableViewCells. </p>

<p>I want to be able to access the data in my UITableViewCells when the UIBarButtonItem of type "Save" is pressed. In order to parse the data from my UITableViewCells to my own class.</p>

<p>I have already written the unwind method in the return controller, and have written the prepareForSegue method in the source controller, got that working. I only need to retrieve the data from the custom UITableViewCells at that specific time (on save, not on finished editing textfield or when a table row has been dis-selected).</p>

<p>What would be the "best practice" to achieve this kind of behaviour?</p>
