Swift Question

generating uisegmentedcontrol buttons with a loop

i am trying to generate sets of segmented control buttons from a loop if given an initial value.

so if the value is 3
i need the loop to generate 3 sets of segmented buttons below each other

this is what i have so far after unsuccessfully trying to adapt codes from tutorials.

var numberOfVillains = ["1", "2", "3", "4"]
var buttonY: CGFloat = 20 // our Starting Offset, could be 0
for number in numberOfVillains {
let segmentController = UISegmentedControl()
//let villainButton = UISegmentedControl(frame: CGRect(x: 50, y: buttonY, width: 50, height: 30)){
buttonY = buttonY + 50 // we are going to space these UIButtons 50px apart
segmentController.frame = CGRect(x:100, y:200, width: 200,height: 30)
//segment frame size
segmentController.insertSegment(withTitle: "1", at: 0, animated: true)
//inserting new segment at index 0
segmentController.insertSegment(withTitle: "2", at: 1, animated: true)
//inserting new segment at index 1
segmentController.backgroundColor = UIColor.blue
//setting the background color of the segment controller
segmentController.selectedSegmentIndex = 0
//setting the segment which is initially selected
segmentController.addTarget(self, action: "segment:", for: UIControlEvents.valueChanged)
//calling the selector method
self.view.addSubview(segmentController)
//adding the view as subview of the segment comntroller w.r.t. main view controller
}

Answer

Every one of your segmented controller has the same frame, so they stack over each other. You have to use buttonY in :

segmentController.frame = CGRect(x:100, y:buttonY, width: 200,height:  30)

I think that you will see a difference
