当在Storyboard中的UITableView中具有带有静态单元格的XIB自定义单元格时，插座为零

Question

I want to use static cells in a UITableView in my storyboard. But also I want those cells to be loaded from a custom .xib file with a custom UITableViewCell subclass.

I want to do this because I want to reuse the cells in multiple table views.

So I added some static cells in storyboard and set the custom class in the identity inspector.

But when I want to access the Outlets in the custom view's awakeFromNib method, they are nil . Even later, they're not beeing instantiated.

How can I do this the right way?

Answer 1

If you are adding static cells in the storyboard, they are functioning like separate .xib files and overriding the custom .xib s you are willing to use.

You should use dynamic cells in your table view if you want to reuse your cells in multiple table views. Dynamic cells are usually more sustainable as well, especially in a larger application.

Answer 2

Ok I figured it out, how this is possible:

I created a container class for my UITableViewCell as it is described in this answer: https://stackoverflow.com/a/34881072/4846592

This class contains a property to get access to the custom cell and loads the XIB in its initializer

Here's the code for Swift 3

class CustomTableViewCellContainer: UIView {    
var cell: CustomTableViewCell!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        cell = Bundle.main.loadNibNamed("CustomTableViewCell", owner: self, options: nil)!.first as! TextFieldTableViewCell
        cell.frame = self.bounds
        cell.autoresizingMask = [.flexibleWidth]
        self.addSubview(cell)
    }
}

Then, I just added a UIView into the ContentView of a static UITableViewCell in the Storyboard and set the height and CustomTableViewCellContainer as custom class name. Finally I added an IBOutlet to it to get access to the custom cell.
