TWTagsCollectionView

功能

在业务中经常会使用各自标签
本组件是方便快速接入，根据你的配置，不需要去额外计算字符串长度
同时支持三种对齐方式，居左，居中，居右
支持自定义 cell 方式

Example

/* 配置对象 TWTagsCollectionCellModel */
/// 剩余文本间隙
public var gap: CGFloat = 4
/// 文本背景色
public var titleBgColor: UIColor = UIColor.white.withAlphaComponent(0.1) 
/// 文本颜色
public var titleColor: UIColor =  UIColor.black // TWColor_2478d2!
/// 文本对齐方式
public var titleAlignment: NSTextAlignment = .center
/// 文本字体
public var font: UIFont = UIFont.systemFont(ofSize: 10)
/// cell 高度
public var height: CGFloat = 14
/// 图片 icon
public var icon: String = ""
/// 图片位置
public var iconPosition: TWTagsCollectionIconPosition = TWTagsCollectionIconPosition.zero
/// cell 边框
public var borderWidth: CGFloat = 0
/// cell 边框颜色
public var borderColor: UIColor?
/// cell 边框弧度
public var cornerRadius: CGFloat = 0
/// 文本
public var title: String = ""
/// 文本宽度
public var titleWidth: CGFloat = 0
