  • Storyboard: Manually, you can add a UIView instance to your Xib, set 'JNSegmentedControl' class and connect @IBOutlet reference.

  • Programmatically: Init ‘JNSegmentedControl’ UIView instance programatically.

      let segmentedControlView = JNSegmentedCollectionView()
      self.view.addSubview(segmentedControlView)

• Setup:

  • JNSegmentedControl Setup:

      self.segmentedControlView.setup(
          items: [NSAttributedString],
          selectedItems: [NSAttributedString],
          options: JNSegmentedCollectionOptions(),
          badgeCounts: [Int]
      )

  To start with default options you can pass (nil) value to the options parameter.

      self.segmentedControlView.setup(
          items: [NSAttributedString],
          selectedItems: [NSAttributedString],
          options: nil,
          badgeCounts: []
      )

  • Configuring items:

  The Segmented Control items & selected items are array of NSAttributedString. In order to set items you need to provide an instance of [NSAttributedString].

  • Default Items:

        var items = [NSAttributedString]()
        let item  = NSAttributedString(string: “Default Item", attributes: [])
        items.append(item)
    

  • Selected Items:

        var items = [NSAttributedString]()
        let item  = NSAttributedString(string: “Selected Item", attributes: [])
        items.append(item)
    

• Handling callback:

      self.segmentedControlView.didSelectItem = { segment in
          print("Selected item: ", segment)
      }

• Options Customization:

  • backgroundColor: Segmented control background color.

  • scrollEnabled: segmented control is scrolling enabled.
  • contentItemLayoutMargins: Content item layout margins from Left and Right.

      JNSegmentedCollectionOptions(
          backgroundColor: UIColor.white,
