UISegmentedControl iOS

A UISegmentedControl object is a horizontal control made of multiple segments, each segment functioning as a discrete button. A segmented control affords a compact means to group together a number of controls.

Creating UISegmentedControl via code

1. Create new instance of UISegmentedControl filled with 3 items (segments):

let mySegmentedControl = UISegmentedControl (items: [“One”, “Two”, “Three”])

2. Setup frame;

mySegmentedControl.frame = CGRect(x: 0.0, y: 0.0, width: 300, height: 50)

3. Make default selection (not that segments are indexed by 0):

mySegmentedControl.selectedSegmentIndex = 0

4. Configure target:

mySegmentedControl.addTarget(self, action: #selector(segmentedValueChanged(_:)), for: .valueChanged)

5 Handle value changed:

func segmentedValueChanged(_ sender:UISegmentedControl!) {
    print("Selected Segment Index is : \(sender.selectedSegmentIndex)")}

6. Add UISegmentedControl to views hierarchy

yourView.addSubview(mySegmentedControl)
