ELSegmentView

Demo

Requirements

iOS 8.0+ / Mac OS X 10.11+ / SnapKit
Xcode 8.0+
Swift 3.0+

Usage

ELSegmentView使用SnapKit设置约束.

  class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        let titles = ["日排行","周排行","月排行","总排行"]
        let segmentView = ELSegmentView(titles: titles)
        view.addSubview(segmentView)
        segmentView.snp.makeConstraints { (make) in
            make.left.top.right.equalToSuperview()
            make.height.equalTo(64)
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()    
    }
  }

满足ELSegmentDelegate可以响应 button 的点击事件

  protocol ELSegmentViewDelegate: class {
    func segmentView(_ segmentView: ELSegmentView, didSelectRowAt index: Int)
  }

在ViewController将代理赋给self segmentView.delegate = self 满足协议

  extension ViewController: ELSegmentViewDelegate {
    func segmentView(_ segmentView: ELSegmentView, didSelectRowAt index: Int) {
        print(index)
    }
  }

协议提供默认实现
