iOS 设置字符串中部分字符（串）链接点击效果

效果如下图

点击10086部分可以响应点击事件

实现方式是用的TTTAttributedLabel

TTTAttributedLabel 是一个常用的富文本开源库，支持各种属性文本、数据探测器，链接等。

设置TTTAttributedLabel

        NSString *linkText = @"10086";
        NSString *promptText = [NSString stringWithFormat:@"如有疑问，请联系客服%@", linkText];
        NSRange linkRange = [promptText rangeOfString:linkText];
        TTTAttributedLabel *textLabel = [[TTTAttributedLabel alloc] initWithFrame: CGRectZero];
        textLabel.font = [UIFont yd_font11];
        textLabel.textColor = [UIColor yd_grey_adadad];
        textLabel.numberOfLines = 0;
        textLabel.delegate = self;
        textLabel.lineBreakMode = NSLineBreakByCharWrapping;
        textLabel.text = promptText;
        NSDictionary *attributesDic = @{(NSString *)kCTForegroundColorAttributeName : (__bridge id)[UIColor yd_blue_FF2196F3].CGColor,
                                        (NSString *)kCTUnderlineStyleAttributeName : @(YES)
                                        };
        textLabel.linkAttributes = attributesDic;
        textLabel.activeLinkAttributes = attributesDic;
        [textLabel addLinkToURL:[NSURL URLWithString:@"testURL"] withRange:linkRange];

响应点击事件

- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url {
    if ([url.absoluteString isEqualToString:@"testURL"]) {
//响应点击事件
    }
}

其他方式

使用 YYText

-(YYLabel *)protocolLabel{
    if (!_protocolLabel) {
        NSString *originText = @"已阅读并同意《用户使用协议》和《个人信息授权协议》";
        NSMutableAttributedString  *text1 = [[NSMutableAttributedString alloc] initWithString:originText];
        text1.yy_font = [UIFont systemFontOfSize:12];
        text1.yy_alignment = NSTextAlignmentLeft;
        text1.yy_color = RGBCOLOR(153, 153, 153);
        [text1 yy_setColor:kMainColor range:[originText rangeOfString:@"《用户使用协议》"]];
        
        [text1 yy_setTextHighlightRange:[originText rangeOfString:@"《用户使用协议》"]//设置点击的位置
                                  color:kMainColor
                        backgroundColor:[UIColor groupTableViewBackgroundColor]
                              tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect)
         {
             NSLog(@"这里是点击事件");
             JTBOpenWebUrlViewController *vc = [[JTBOpenWebUrlViewController alloc] init];
             vc.url = JTB_H5_USER_REGISTER;
             [self.navigationController pushViewController:vc animated:YES];
         }];
        [text1 yy_setColor:kMainColor range:[originText rangeOfString:@"《个人信息授权协议》"]];
        
        [text1 yy_setTextHighlightRange:[originText rangeOfString:@"《个人信息授权协议》"]//设置点击的位置
                                  color:kMainColor
                        backgroundColor:[UIColor groupTableViewBackgroundColor]
                              tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect)
         {
             NSLog(@"这里是点击事件");
             JTBOpenWebUrlViewController *vc = [[JTBOpenWebUrlViewController alloc] init];
             vc.url = JTB_H5_USER_GET_INFO_AGREE;
             [self.navigationController pushViewController:vc animated:YES];
         }];
        YYLabel *titleLb                         = [[YYLabel alloc] init];
        titleLb.userInteractionEnabled  = YES;
        titleLb.numberOfLines           = 2;
        titleLb.attributedText = text1;
        titleLb.textVerticalAlignment   = YYTextVerticalAlignmentCenter;
        titleLb.backgroundColor = [UIColor clearColor];
        _protocolLabel = titleLb;
    }
    return _protocolLabel;
}
