A powerful and useful segment tool, segment controller and custom segment titleView、 segment contentView. Written in Swift. （仿 美团，今日头条，网易，淘宝标题滚动视图）.
To run the example project, clone the repo, and run pod install from the Example directory first.
STSegmentPageView is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'STSegmentPageView'Download the project, and drag Folder "STSegmentPageView"into your project.
Use STSegmentPageViewController, which has integrate title view and content view, like:
// use default title view configure
let config = STSegmentPageTitleViewConfigure()
let titles = ["推荐","热点","视频","娱乐","问答","北京","朝阳","地方","八卦","综艺","推荐","热点","视频","娱乐","问答","北京","朝阳","地方","八卦","综艺"]
var models = titles.map { (title) -> STSegmentModel in
let model = STSegmentModel()
let controller = SecondViewController()
controller.label.text = title
model.segmentTitle = title
model.segmentController = controller
return model
}
//使用自定义高度
let segmentVC = STSegmentPageViewController(childrenModels: models, titleViewH: 40, titleConfig: config)
segmentVC.view.frame = CGRect(x: 0, y: 64, width: view.width, height: view.height - 64 )
segmentVC.addSegmentController(toParentController: self)Use custom title view and content view to implement the function, developer must implement STSegmentContentViewDelegate , STSegmentTitleViewDelegate , so that title view and content view be associated with each other.
let titles = ["推荐","热点","视频","娱乐","问答","北京","朝阳","地方","八卦","综艺","推荐","热点","视频","娱乐","问答","北京","朝阳","地方","八卦","综艺"]
let config = STSegmentPageTitleViewConfigure()
// title view
pageTitleView = STSegmentTitleView(config:config ,titles: titles)
pageTitleView!.frame = CGRect(x: 0, y: 64, width: view.width, height: 48)
view.addSubview(pageTitleView!)
pageTitleView?.delegate = self
// content view
var vcs = [UIViewController]()
for (i,_) in titles.enumerated(){
let controller = SecondViewController()
controller.label.text = "\(i)"
vcs.append(controller)
}
pageView = STSegmentContentView(frame: CGRect(x: 0, y: (pageTitleView?.frame.maxY ?? 0), width: view.width, height: view.height - (pageTitleView?.frame.maxY ?? 0) ), childrenControllers: vcs, parentVC:self)
pageView?.delegate = self
view.addSubview(pageView!)
///// Delegate
extension ViewController : STSegmentTitleViewDelegate{
func didSelectedSegmentTitleViewItemAt(atIndex index: Int) {
pageView?.didSelectedItemAtIndex(atIndex: index)
}
}
extension ViewController : STSegmentContentViewDelegate{
func pageContentViewDidScrollToItem(atIndex targetIndex: Int) {
pageTitleView?.didSelectedTitleItemAtIndex(atIndex: targetIndex)
}
func pageContentViewDidScroll(progress: CGFloat, originIndex: Int, targetIndex: Int) {
pageTitleView?.updateTitleViewWhenContentViewDrag(progress: progress, fromIndex: originIndex, endIndex: targetIndex)
}
} // MARK: - 指示器
/// 指示器style，默认为下划线

/// 指示器滚动样式,默认随着内容视图滚动而动

/// 指示器颜色,默认红色
public var indicatorColor : UIColor = .red
/// - 指示器高度
/// - 下划线样式下，固定长度样式，默认高度是2.f
/// - 遮罩样式下，默认高度和标题文本高度一致，如若大于标题视图高度，则为标题视图高度,取值范围：标题高度~标题视图高度
/// - 其他情况不做处理
public var indicatorHeight : CGFloat = 2.0
/// 指示器圆角值，默认0.1
public var indicatorCornerRadius : CGFloat = 0.1
/// - 指示器宽度,只在style类型为fixed情况下有效，默认值20.0
/// - 在fixed样式下，宽度只会和文本长度一直
public var indicatorWidthWhenFixedStyle : CGFloat = 20.0
/// 指示器动画时间，取值范围 0.1 ~ 0.4, 超出取边界值
public var indicatorAnimationTime : Double = 0.1
//MARK: - 底部底线 默认值Hex-color #eaeaea RGB(234,234,234)
public var bottomSeparatorColor : UIColor = UIColor(red: 234/255.0, green: 234/255.0, blue: 234/255.0, alpha: 1.0)

//MARK: - 标题设置
/// 标题字体，默认系统15号字体
public var titleFont : UIFont = UIFont.systemFont(ofSize: 15)
/// 标题未选状态颜色，默认黑色
public var titleNormalColor : UIColor = .black
/// - 标题选中状态颜色，默认红色
/// - 遮罩模式，需要把指示器和字体颜色设为不一致，不然标题会看不到
public var titleSelectedColor : UIColor = .red
/// 标题之间的间隔，默认值15
public var spaceBetweenTitles : CGFloat = 15.0
/// 第一个标题左侧之间的间隔，默认值20
public var spaceBetweenFirstTitleAndLeftSide : CGFloat = 20
/// - 选中标题之后是否缩放，默认true
/// - true的情况下，设置缩放系数deltaScaleIndex才生效
/// - 指示器在default，shade样式下默认随着一起缩放; fixed不会
public var wouldScaledWhenSelected : Bool = true
/// - 缩放系数，默认0.1
/// - 取值范围 -0.1 ~ 0.1， 负数缩小，0不缩放，正数放大

/// - 使用右侧按钮，默认是false不使用。
/// - true的情况下，需要设置rightButton才会显示该按钮
public var wouldUseRightButton : Bool = false
/// - 右侧按钮,如为nil，则相当于wouldUseRightButton = false
/// - 点击事件可以执行按钮点击事件Block "didClickRightButtonAt"，也可以外部直接addTarget
/// - 按钮在标题视图中的宽高，为外部设置的宽高。如果高度超出了标题视图，按照实际设置的宽高比例缩放
/// - 外部用户需要设计好自己的按钮样式:
/// - 包括字体属性，以及按钮宽高，否认按钮的默认宽高将是标题视图高
public var rightButton : UIButton?
/// 右侧按钮的左侧效果，默认有效果,前提是设置了右侧按钮
public var showRightButtonSeparator : Bool = true
/// 右侧按钮点击事件
