针对项目需求使用TYAttributedLabel，需要修改一下TYAttributedLabel源码

实现如图效果，部分文字显示背景高亮，并点击时是另外的高亮颜色

第一步

在TYTextContainer.h文件中添加属性

@property (nonatomic, strong) NSMutableArray *textLinkStorages;//在.m中懒加载textLinkStorages

在TYTextContainer+Extended.m文件中修改

- (void)appendLinkWithText:(NSString *)linkText linkFont:(UIFont *)linkFont linkColor:(UIColor *)linkColor underLineStyle:(CTUnderlineStyle)underLineStyle linkData:(id)linkData
{
    TYLinkTextStorage *linkTextStorage = [[TYLinkTextStorage alloc]init];
    linkTextStorage.text = linkText;
    linkTextStorage.font = linkFont;
    linkTextStorage.textColor = linkColor;
    linkTextStorage.linkData = linkData;
    linkTextStorage.underLineStyle = underLineStyle;
    [self appendTextStorage:linkTextStorage];
    [self.textLinkStorages addObject:linkTextStorage];//添加
}

- (void)addLinkWithLinkData:(id)linkData linkColor:(UIColor *)linkColor underLineStyle:(CTUnderlineStyle)underLineStyle range:(NSRange )range
{
    TYLinkTextStorage *linkTextStorage = [[TYLinkTextStorage alloc]init];
    linkTextStorage.range = range;
    linkTextStorage.textColor = linkColor;
    linkTextStorage.linkData = linkData;
    linkTextStorage.underLineStyle = underLineStyle;
    [self addTextStorage:linkTextStorage];
    [self.textLinkStorages addObject:linkTextStorage];//添加
}

第二步

在TYAttributedLabel.m中修改

- (void)drawRect:(CGRect)rect {////}

在代码

if (_highlightedLinkBackgroundColor && [_textContainer existLinkRectDictionary]) {
        [self drawSelectionAreaFrame:_textContainer.frameRef InRange:_clickLinkRange radius:_highlightedLinkBackgroundRadius bgColor:_highlightedLinkBackgroundColor];
    }

后添加代码

    for (TYLinkTextStorage *storage in _textContainer.textLinkStorages) {
        NSRange storageRange = storage.realRange;
        if (_clickLinkRange.length == 0) {
            [self drawSelectionAreaFrame:_textContainer.frameRef InRange:storageRange radius:_highlightedLinkBackgroundRadius bgColor:[UIColor blueColor]];
        } else {
            if (_clickLinkRange.location != storageRange.location || _clickLinkRange.length != storageRange.length) {
                  [self drawSelectionAreaFrame:_textContainer.frameRef InRange:storageRange radius:_highlightedLinkBackgroundRadius bgColor:[UIColor blueColor]];
            }
        }
    }

修改完成后，调用TYattributedLabel如下代码：

    NSString *testText = @"I'm still very much figuring out what I want to do with my life, but I can honestly say now that I feel very proud of where I am right now. <P>I've written about the teachers in high school and college I had that made a big impact on me, but I haven't mentioned the <b>person</b> that made the biggest difference.";
    NSArray *words = @[@"I'm",@"I",@"person",@"written",@"a",@"I've"];

    TYAttributedLabel *textLabel = [[TYAttributedLabel alloc] init];
    textLabel.textColor = [UIColor blackColor];
    textLabel.delegate = self;
    textLabel.font = [UIFont systemFontOfSize:16.0f];
    textLabel.lineBreakMode = kCTLineBreakByWordWrapping;
    [self.view addSubview:textLabel];
    textLabel.frame = CGRectMake(10, 100, self.view.frame.size.width-20, self.view.frame.size.height);
    textLabel.attributedText = [testText dr_HtmlStringWithFontSize:16.0f];
    
    NSString *string = textLabel.text;
    [string enumerateSubstringsInRange:NSMakeRange(0, string.length-1) options:NSStringEnumerationByWords usingBlock:^(NSString * _Nullable substring, NSRange substringRange, NSRange enclosingRange, BOOL * _Nonnull stop) {
       
        if([words containsObject:substring]) {
            [textLabel addLinkWithLinkData:substring linkColor:[UIColor  colorWithHex:0xffb211] underLineStyle:kCTUnderlineStyleNone range:substringRange];
        }
    }];
