Custom Accessory Button in UITableViewCell

I am trying to add a custom button in the Accessory View for a UITableViewCell.

I have added the following code:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {      
       // ....     
       let button = UIButton(type: .custom)
       button.setImage(UIImage(named: "arrow-right-light.png")?.maskWithColor(color: .white), for: .normal)
       button.addTarget(self, action: #selector(buttonTest), for: .touchUpInside)
       button.tag = indexPath.row
       cell.accessoryView = button
       // ...

However, I don't see the button show up on in the Accessory View.

Solution

I can think of two possible reasons:

The problem might be that the button has no size, so it's invisible. Add this line, after setting the image:
```
button.sizeToFit()
```
Another possibility is that you have no image named "arrow-right-light.png". That wouldn't crash your existing code, but it would prevent the button from having any image so you wouldn't see it. Try saying UIImage(named: "arrow-right-light.png")! instead, just as a test; if you crash, that was indeed the problem, and then you can figure out what the correct name is.
