How to set default selection in segmented control

[appsird]

The included sample form contains a segmented control. I attempt to set the default selected value using "row.value = 1 as AnyObject", though this does not seem to work. How does one set the default selection for the segmented control.

Thanks again for all of your efforts.

IMHO it is a bug, but I have a workaround for you ;-)

Just use the appearance dictionary to set the index of the segmented control.

(Code from the example of the project)

        row = FormRowDescriptor(tag: Static.segmented, type: .segmentedControl, title: "Priority")
        row.configuration.selection.options = ([0, 1, 2, 3] as [Int]) as [AnyObject]
        row.configuration.selection.optionTitleClosure = { value in
            guard let option = value as? Int else { return "" }
            switch option {
            case 0:
                return "None"
            case 1:
                return "!"
            case 2:
                return "!!"
            case 3:
                return "!!!"
            default:
                return ""
            }
        }

        //this alone has just no effect
        row.value=2 as AnyObject?
        
        row.configuration.cell.appearance = ["titleLabel.font" : UIFont.boldSystemFont(ofSize: 30.0), "segmentedControl.tintColor" : UIColor.red]
        
        //you can either set the appearance dictionary as a whole
        row.configuration.cell.appearance = ["titleLabel.font" : UIFont.boldSystemFont(ofSize: 30.0), "segmentedControl.tintColor" : UIColor.red, "segmentedControl.selectedSegmentIndex": 2 as AnyObject]
        
        //or set the value in the dicionary afterwards
        row.configuration.cell.appearance["segmentedControl.selectedSegmentIndex"]=2 as AnyObject
        
        //the best way IMHO is to set the index via the value (in that way the row.value is the model for the segmented control, like it should be)
        row.configuration.cell.appearance["segmentedControl.selectedSegmentIndex"]=row.value
        
        section4.rows.append(row)

Running that code the segmented control is pre filled with your set value

I posted your questions (and my answer) on stackoverflow.

Thorsten, thank you kindly for your response.

Likewise, would like to present a slider control. The following has no affect, i.e. the default position is to the far left, or 0:

    row.configuration.stepper.maximumValue = 1000000.0
    row.configuration.stepper.minimumValue = 100.0
    row.configuration.stepper.steps = 2.0
    row.value = 20000 as AnyObject

Would appreciate also how to set the default slider value.

Disregard. This can be accomplished similarly, e.g.

    row.configuration.stepper.maximumValue = 1000000.0
    row.configuration.stepper.minimumValue = 100.0
    row.configuration.stepper.steps = 2.0
    row.configuration.cell.appearance["sliderView.value"] = 200000 as AnyObject
