一、页面介绍

1. YYSegmentConfig：配置文件
2. YYSegmentViewController：控制器
3. YYContainerScrollView：控制器view底部的ScrollView
4. YYControllerPageView：控制器view的容器
5. YYSegmentedView：上边title的底部view
6. YYSegmentItemView：装title和指示器的view
7. YYIndicatorView：指示器view

二、添加控制器方法

    1. 直接添加控制器的view

let config = YYSegmentConfig()
let vc = YYSegmentViewController(config)
self.addChild(vc)
vc.view.frame = CGRect(x: 0, y: 130, width: view.bounds.size.width, height: 600)
self.view.addSubview(vc.view)

注意事项：一定要添加 self.addChild(vc)，并且在初始化完成之后就得添加

    2. 继承 YYSegmentViewController

注意事项：在 viewDidLoad() 方法中，在调用 super.viewDidLoad() 方法之前设置 config

三、使用技巧

    1. 设置 Title

oneVc.tabBarItem.title = "第一章"

如果想改变 Title，可直接设置 tabBarItem.title

    2. 设置角标

oneVc.tabBarItem.badgeValue = "112"

如果想改变角标，可直接设置 tabBarItem.badgeValue

    3. 指示器

当设置 itemIndicatorViewShapeStyle 类型为椭圆和横杆时，itemIndicatorViewWidthChangeStyle不再起作用，默认为横杆

    4. 页面刷新

当子view是普通view，想刷新整个页面时，最底层 YYContainerScrollView 是ScrollView，可添加刷新控件，当子view是 tableView 时，可设置刷新方式，整个刷新还是列表刷新

vc.containerScrView.mj_header = MJRefreshNormalHeader(refreshingTarget: self, refreshingAction: #selector(refreshControlAction))

当设置了headerView时，需要多一个设置，高度为 headerView 的高度

vc.containerScrView.mj_header.ignoredScrollViewContentInsetTop = 300

    5. 自定义指示器

指示器view为 YYIndicatorView，可进行自定义，示例代码如下

vc.initDone = { [weak self] in
    guard let this = self else {return}
    let indicatorViewContentView = this.vc.segmentCtlView.indicatorView.contentView
    let mixIndicatorView = MixIndicatorView(frame: indicatorViewContentView.bounds)
    indicatorViewContentView.addSubview(mixIndicatorView)
    mixIndicatorView.autoresizingMask = [.flexibleWidth,.flexibleHeight]
}

config.itemIndicatorViewShapeStyle = .background(color: UIColor.clear, img: nil)

class MixIndicatorView: UIView {
    let ellipseView = UIView()
    let crossBarView = UIView()
    override init(frame: CGRect) {
        super.init(frame: frame)
        ellipseView.backgroundColor = UIColor.lightGray.withAlphaComponent(0.8)
        ellipseView.frame = CGRect.init(x: 0, y: 0, width: bounds.width, height: 20)
        ellipseView.center = CGPoint.init(x: bounds.width/2, y: bounds.height/2)
        ellipseView.layer.cornerRadius = 10
        ellipseView.autoresizingMask = [.flexibleWidth,.flexibleTopMargin,.flexibleBottomMargin]
        addSubview(ellipseView)

        let crossBarViewHight:CGFloat = 3
        crossBarView.backgroundColor = UIColor.red
        crossBarView.frame = CGRect.init(x: 0, y: bounds.height - crossBarViewHight, width: bounds.width, height: crossBarViewHight)
        addSubview(crossBarView)
        crossBarView.autoresizingMask = [.flexibleWidth,.flexibleTopMargin,.flexibleBottomMargin]
    }
    
    public required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

组合样式

三、使用示例

oneVc.tabBarItem.title = "第一章"
twoVc.tabBarItem.title = "第二章"
oneVc.tabBarItem.badgeValue = "112"

let headerV = UIImageView(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 300))
headerV.image = UIImage(named: "longzhu")
headerV.contentMode = .scaleAspectFill
headerV.backgroundColor = UIColor.red
        
let config = YYSegmentConfig()
config.containerControllerArr = [oneVc, twoVc]
let width = view.bounds.size.width / 2
config.segmentBackgroundColor = .yellow
config.headView = headerV
config.itemSpacing = 10
config.itemTitleSelectedScale = 1.5
config.itemWidthStyle = .equalToTitleWidth(margin: 0)
config.segmentControlHeight = 100
config.itemIndicatorViewBackgroundColor = UIColor.blue
config.itemBadgeStyle = .round
config.itemBadgeTitleColor = .blue
config.itemBadgeValueLabelOffset = CGPoint(x: 0, y: -5)
config.itemViewSegmentSelectedStyle = .gradient
config.itemBadgeSize = CGSize(width: 10, height: 10)
config.refreshType = .container
config.segmentControlPositionType = .top
config.itemIndicatorViewWidthChangeStyle = .stationary(baseWidth: width)
config.itemIndicatorViewShapeStyle = .crossBar(widthChangeStyle: .equalToItemWidth(margin: 0), height: 6)
config.isShowItemSeparatorLineView = true
config.itemSeparatorLineTopBottomMargin = (5, 5)
config.itemBadgeTitleFont = 9
    
let vc = YYSegmentViewController(config)
self.addChild(vc)
vc.view.frame = CGRect(x: 0, y: 130, width: view.bounds.size.width, height: 600)
self.view.addSubview(vc.view)
vc.containerScrView.mj_header = MJRefreshNormalHeader(refreshingTarget: self, refreshingAction: #selector(refreshControlAction))vc.containerScrView.mj_header.ignoredScrollViewContentInsetTop = 300
vc.segmentCtlView.clickAnimation = false
vc.pageView.isScrollEnabled = false
vc.segmentCtlView.delegate = self
vc.scrollViewDragTopOffsetYBlock = { (scr, offsetY) in

}
vc.initDone = { 

}
