TGPageView

类似网易新闻的导航条，支持滚动、缩放动画、渐变、遮罩等，可以任意组合各效果，史上最赞

如何使用

let pageViewFrame = CGRect(x: 0, y: 64, width: view.bounds.width, height: view.bounds.height - 64 )//非scrollView设置64

1 默认不可滚动，底下有跟踪滚动条（下划线） 等分

let titles = ["推荐","视频","图片","段子","投票"]

let style = TGPageStyle()

2 滚动模式，底下有跟踪滚动条（下划线） 不等分，根据文字大小设置下划线

let titles = ["推荐","视频","这是一个测试","图片","段子","投票","排行","互动区","网红","社会","美女","冷知识","游戏"]

let style = TGPageStyle()

style.isScrollEnable = true//滚动模式

3 无跟踪滚动条（下划线） 用遮罩 缩放支持

let titles = ["推荐","视频","这是一个测试","图片","段子","投票","排行","互动区","网红","社会","美女","冷知识","游戏"]

let style = TGPageStyle()

style.isScrollEnable = true

style.isNeedTitleScale = true//缩放支持

style.isShowCoverView = true//用遮罩

4 遮罩加跟踪滚动条，系统默认情况下使用遮罩时会隐藏底部的跟踪滚动条，若要同时有滚动条，则在设置遮罩后再设置滚动条

let titles = ["推荐","视频","这是一个测试","图片","段子","投票","排行","互动区","网红","社会","美女","冷知识","游戏"]

let style = TGPageStyle()

style.isScrollEnable = true

style.isNeedTitleScale = true

style.isShowCoverView = true

style.isShowBottomLine = true

56789... 根据自己想要的效果自由配置style，如等分并缩放支持

let titles = ["推荐","视频","图片","段子","投票"]

let style = TGPageStyle()

style.isNeedTitleScale = true//缩放支持

style.bottomLineExtendWidth = 18//相当于inset，因为transform会影响frame，用bottomLineExtendWidth改变底部跟踪滚动条（下划线）的缩进

设置完pageViewFrame titles style 后就可以开始用了

var childVCs = [UIViewController]()

for _ in 0..<titles.count {

let vc = UIViewController()

vc.view.backgroundColor = UIColor.random()

childVCs.append(vc)

}

let pageView = TGPageView(frame: pageViewFrame, titles: titles, titleStyle: style, childVCs: childVCs, parentVC: self)

view.addSubview(pageView)
