Maintained by Hao.

You want to add pod 'HSegmentControl', '~> 2.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'HSegmentControl', '~> 2.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

Demo

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

HSegmentControl is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "HSegmentControl"

Swift version	version
2.3	2.0.x
3.0	2.1.0 or later

Usage

Add to View

You can either add HSegmentControl programmatically with code

let segmentControl = HSegmentControl()
view.addSubview(segmentControl)
// Customized configuration
// .
// .
// .

or simply drag and drop an UIView in storyboard (Interface Builder) and set the class to HSegmentControl.

Data source protocol

Make sure your controller implements the HSegmentControlDataSource protocol and is set to the dataSource of the HSegmentControl

class ViewController: UIViewController, HSegmentControlDataSource{
    // .
  // .
  // .
  override func viewDidLoad(){
        super.viewDidLoad()   
        segmentControl.dataSource = self
        //.
      //.
      //.
  }
    // .
  // .
  // .
  // MARK: - HSegmentControlDataSource protocol
    func numberOfSegments(segmentControl: HSegmentControl) -> Int {
        return 5
    }
    
    func segmentControl(segmentControl: HSegmentControl, titleOfIndex index: Int) -> String {
        return ["1","two", "threeeeeee", "four", "five"][index]
    }
    
    // Optional
    func segmentControl(segmentControl: HSegmentControl, segmentBackgroundViewOfIndex index: Int) -> UIView {
        let view = UIView()
        view.backgroundColor = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 1)
        return view
    }
}

Configure HSegmentControl

override func viewDidLoad(){
    super.viewDidLoad()
    segmentControl.dataSource = self
    //.
  //.
  //.
  // Customized configuration
  segmentControl.numberOfDisplayedSegments = 3
    segmentControl.selectedTitleFont = UIFont.boldSystemFontOfSize(17)
    segmentControl.selectedTitleColor = UIColor.darkGrayColor()
    segmentControl.unselectedTitleFont = UIFont.systemFontOfSize(17)
    segmentControl.unselectedTitleColor = UIColor.blackColor()
    segmentControl.segmentIndicatorImage = UIImage(named: "ind_img")
    segmentControl.segmentIndicatorViewContentMode = UIViewContentMode.Bottom
    segmentControl.segmentIndicatorView.backgroundColor = UIColor.whiteColor()
}

Value changed

As you did in any other UIControl, link the valueChanged functions to delegate action when value changed.

@IBAction func valueChanged(sender: AnyObject){
    print("value did change to \((sender as! HSegmentControl).selectedIndex)")
}

Change value manually

Simply set the selectedIndex variable

segmentControl.selectedIndex = 2

Note that function valueChanged(sender:) will not be called when you set selectedIndex manually.
