之前写过关于富文本的处理，确实略显麻烦文章链接，相比而言，YYText使用简单且功能强大。当然汲及到富文本链接，多用TTTAttributedLabel。具体项目中MLEmojiLabel涉及表情处理的话感觉更方便一些。

YYLabel 设置字体样式更方便简洁
TTT 及其子类 ML 设置字体样式等感觉代码有点烦琐，处理链接方便，且可以很方便准确的处理给定文字的高度处理。

YYText

基础用法

#import "ViewController.h"
#import <YYText.h>

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
#pragma mark - 基本用法
    //基本用法和UILabel相似
    YYLabel *label = [[YYLabel alloc]init];
    label.frame = CGRectMake(0, 0, 200, 200);
    label.center = self.view.center;
    label.numberOfLines = 2;
    [self.view addSubview:label];
    
#pragma mark - 属性文本
    
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc]initWithString:@"Change the fucking world"];
    str.yy_font = [UIFont systemFontOfSize:20];
    str.yy_color = [UIColor orangeColor];
    [str yy_setColor:[UIColor greenColor] range:NSMakeRange(7, 4)];

     //*******也可以直接搜索相应文字改变属性******//
     //NSRange range= [[text string] rangeOfString:@"对这个世界如果你有太多的抱怨" options:NSCaseInsensitiveSearch];

    //行间距
    str.yy_lineSpacing =10;


    //文字描边（空心字）默认黑色，必须设置width
    [text yy_setStrokeColor:[UIColor orangeColor] ];
    [text yy_setStrokeWidth:@(2) ];


     YYTextDecoration *decoration = 
            [YYTextDecoration decorationWithStyle:YYTextLineStyleSingle
                                            width:@(1)
                                            color:[UIColor blueColor]];
    //删除样式
    [text yy_setTextStrikethrough:decoration range:range2];
    //下划线
    [text yy_setTextUnderline:decoration range:range2];


    //阴影
    NSShadow *shadow = [[NSShadow alloc]init];
    shadow.shadowColor = [UIColor grayColor];
    shadow.shadowOffset = CGSizeMake(1, 1.5);
    str.yy_shadow  = shadow;
    
    //文本内阴影
    YYTextShadow *shadow = [YYTextShadow new];
    shadow.color = [UIColor redColor];
    shadow.offset = CGSizeMake(0, 2);
    shadow.radius = 1;
    [str yy_setTextInnerShadow:shadow ];


    //首行缩进
    str.yy_firstLineHeadIndent = 10;

    //背景框
    //多行显示时效果会不太如愿          
    str.yy_textBorder = [ YYTextBorder borderWithLineStyle:YYTextLineStylePatternCircleDot
                                                 lineWidth:1
                                               strokeColor:[UIColor greenColor]];
    str.yy_textBorder.cornerRadius = 3;
    str.yy_textBorder.insets = UIEdgeInsetsMake(0, -2, 0, -2);
    

  #pragma mark - 高亮显示
    
   [str yy_setTextHighlightRange:range
                         color:[UIColorr redColor]
               backgroundColor:[UIColor greenColor]
                     tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect){
                        //点击事件
                     }];
    
    //一定要放在最后
    label.attributedText = str;


}

YYTextRubyAnnotation

    ruby = [YYTextRubyAnnotation new];
    ruby.textBefore = @"wén";
    [one yy_setTextRubyAnnotation:ruby range:[one.string rangeOfString:@"文"]];
    
    ruby = [YYTextRubyAnnotation new];
    ruby.textBefore = @"zì";
    ruby.alignment = kCTRubyAlignmentCenter;
    [one yy_setTextRubyAnnotation:ruby range:[one.string rangeOfString:@"字"]];
    
    YYLabel *label = [YYLabel new];
    label.backgroundColor = [UIColor whiteColor];
    label.attributedText = one;
    label.frame = CGRectMake(0, 10, self.view.frame.size.width, 200);
