cocoapods 導入三方庫

  pod 'YBAttributeTextTapAction'

頭文件添加

#import "UILabel+YBAttributeTextTapAction.h"

demo代碼如下：

NSString * showText = @"秦始皇是出生於趙國都城邯鄲（今邯鄲），並在此度過了少年時期。前247年，13歲時即王位。 前238年，22歲時，在故都雍城舉行了國君成人加冕儀式，開始“親理朝政”，除掉呂不韋、嫪毐等人， 重用李斯、尉繚，自前230年至前221年，先后滅韓、趙、魏、楚、燕、齊六國，wo39歲時完成了統一中國大業，建立起一個以漢族為主體統一的中央集權的強大國家——秦朝，並奠定中國本土的疆域。";
    UILabel *comment = [UILabel new];
    comment.textColor = [UIColor redColor];
    comment.numberOfLines = 0;
    comment.attributedText = [self getAttributeWith:@[@"邯鄲"] string:showText orginFont:15 orginColor:[UIColor darkGrayColor] attributeFont:18 attributeColor:[UIColor blueColor]];
    [self.view addSubview:comment];
    [comment mas_makeConstraints:^(MASConstraintMaker *make) {
           make.top.equalTo(@200);
        make.left.equalTo(@50);
        make.right.equalTo(@-50);
       }];
    [comment yb_addAttributeTapActionWithStrings:@[@"wo",@"邯鄲",@"邯鄲"] tapClicked:^(UILabel *label, NSString *string, NSRange range, NSInteger index) {
        NSLog(@"%@",string);
    }];
