ScrollableSegmentedControl

CI Status Version License Platform

ScrollableSegmentedControl is replacement for UISegmentedControl that becomes scrollable when the total width of all segments exceeds the width of the control itself.

ScrollableSegmentedControl supports 4 styles of segments: text only, image only, text with image on top and text with image on left.

| Text Only | Image Only | |-------------------------------|---------------------------------| |Demo |Demo |

| Image On Top | Image On Left | |-------------------------------|---------------------------------| |Demo |Demo |

Support

  • Xcode 10.2+
  • Swift 5.0+
  • iOS 9.0+

Usage

ScrollableSegmentedControl is designed to be used exactly same as UISegmentedControl. methods and properties are deliberately named same or very similar to ones found in UISegmentedControl.

@IBOutlet weak var segmentedControl: ScrollableSegmentedControl!

override func viewDidLoad() { super.viewDidLoad()

segmentedControl.segmentStyle = .textOnly
segmentedControl.insertSegment(withTitle: "Segment 1", image: #imageLiteral(resourceName: "segment-1"), at: 0)
segmentedControl.insertSegment(withTitle: "Segment 2", image: #imageLiteral(resourceName: "segment-2"), at: 1)
segmentedControl.insertSegment(withTitle: "Segment 3", image: #imageLiteral(resourceName: "segment-3"), at: 2)
segmentedControl.insertSegment(withTitle: "Segment 4", image: #imageLiteral(resourceName: "segment-4"), at: 3)
segmentedControl.insertSegment(withTitle: "Segment 5", image: #imageLiteral(resourceName: "segment-5"), at: 4)
segmentedControl.insertSegment(withTitle: "Segment 6", image: #imageLiteral(resourceName: "segment-6"), at: 5)

segmentedControl.underlineSelected = true

segmentedControl.addTarget(self, action: #selector(TableViewController.segmentSelected(sender:)), for: .valueChanged)

// change some colors 
segmentedControl.segmentContentColor = UIColor.white
segmentedControl.selectedSegmentContentColor = UIColor.yellow
segmentedControl.backgroundColor = UIColor.black

// Turn off all segments been fixed/equal width. 
// The width of each segment would be based on the text length and font size. 
segmentedControl.fixedSegmentWidth = false

}

func segmentSelected(sender:ScrollableSegmentedControl) { print("Segment at index (sender.selectedSegmentIndex) selected") }

Using appearance proxy to change some colors

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let segmentedControlAppearance = ScrollableSegmentedControl.appearance()
    segmentedControlAppearance.segmentContentColor = UIColor.white
    segmentedControlAppearance.selectedSegmentContentColor = UIColor.yellow
    segmentedControlAppearance.backgroundColor = UIColor.black

return true

}

Configuring custom title attributes via setTitleTextAttributes method

let largerRedTextAttributes = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 16), NSAttributedStringKey.foregroundColor: UIColor.red]
let largerRedTextHighlightAttributes = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 16), NSAttributedStringKey.foregroundColor: UIColor.blue]
let largerRedTextSelectAttributes = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 16), NSAttributedStringKey.foregroundColor: UIColor.orange]

segmentedControl.setTitleTextAttributes(largerRedTextAttributes, for: .normal) segmentedControl.setTitleTextAttributes(largerRedTextHighlightAttributes, for: .highlighted) segmentedControl.setTitleTextAttributes(largerRedTextSelectAttributes, for: .selected)

See the Demo project for example on how to use it.
