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;
