cocoapods 导入三方库

  pod 'YBAttributeTextTapAction'

头文件添加

#import "UILabel+YBAttributeTextTapAction.h"

demo代码如下：

NSString * showText = @"秦始皇是出生于赵国都城邯郸（今邯郸），并在此度过了少年时期。前247年，13岁时即王位。?前238年，22岁时，在故都雍城举行了国君成人加冕仪式，开始“亲理朝政”，除掉吕不韦、嫪毐等人，?重用李斯、尉缭，自前230年至前221年，先后灭韩、赵、魏、楚、燕、齐六国，wo39岁时完成了统一中国大业，建立起一个以汉族为主体统一的中央集权的强大国家——秦朝，并奠定中国本土的疆域。";
