YYText参考文档
TTTAttributedLabel参考文档
富文本的处理原生文案略显麻烦文章链接。
相比而言，YYText使用简单且功能强大，YYLabel 设置字体样式更方便简洁。另外TTTAttributedLabel也挺不错的。
YYText
基础用法
//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;
label.textAlignment = NSTextAlignmentCenter;
[self.view addSubview:label];
属性文本
NSMutableAttributedString *str = [[NSMutableAttributedString alloc]initWithString:@"Change the fucking world"];
//字体
str.yy_font = [UIFont systemFontOfSize:20];
//颜色
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;
//首行缩进
str.yy_firstLineHeadIndent = 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) ];
//文字装饰
YYTextDecoration * decoration
= [YYTextDecoration decorationWithStyle:YYTextLineStyleSingle
width:@(1)
color:[UIColor blueColor]];
//删除样式
[text yy_setTextStrikethrough:decoration
range:range];
//下划线
[text yy_setTextUnderline:decoration
range:range];
//阴影
NSShadow *shadow = [[NSShadow alloc]init];
shadow.shadowColor = [UIColor grayColor];
shadow.shadowOffset = CGSizeMake(1, 1.5);
shadow.radius = 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 ];
//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 - 可点击高亮显示
[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;
}

YYTextLayout
NSAttributedString *text = ...
CGSize size = CGSizeMake(100, CGFLOAT_MAX);
YYTextLayout *layout = [YYTextLayout layoutWithContainerSize:size

// get text bounding
layout.textBoundingRect; // get bounding rect

[layout rectForRange:[YYTextRange rangeWithRange:NSMakeRange(10,2)]];
[layout selectionRectsForRange:[YYTextRange rangeWithRange:NSMakeRange(10,2)]];
// text layout display
YYLabel *label = [YYLabel new];
label.size = layout.textBoundingSize;
label.textLayout = layout;
YYTextRubyAnnotation
NSMutableAttributedString *one = [[NSMutableAttributedString alloc] initWithString:@"这是用汉语写的一段文字。"];
one.yy_font = [UIFont boldSystemFontOfSize:30];

TTTAttributedLabel 的懒加载

_label.delegate = self;
_label.lineSpacing = 10;
/*
要放在`text`,
`setText:`
`setText:afterInheritingLabelAttributesAndConfiguringWithBlock:前面才有效
*/

NSTextCheckingTypeAddress|

//链接正常状态文本属性
_label.linkAttributes = @{

};
//链接高亮状态文本属性
_label.activeLinkAttributes = @{
NSForegroundColorAttributeName:[UIColor redColor],

return _label;
TTTAttributedLabel 是代理方法实现所有点击回调
#pragma mark - TTTAttributedLabelDelegate
//点击链接
- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url{
NSLog(@"linkClick");
[[UIApplication sharedApplication] openURL:url];
}
//点击地址链接
- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithAddress:(NSDictionary *)addressComponents{
NSLog(@"addressClick");
NSLog(@"detailAdd:%@,lontitude:%f,latitude:%f",
addressComponents[@"detailAdd"],
[addressComponents[@"lontitude"] floatValue],
[addressComponents[@"latitude"] floatValue]);
}
//拨的电话
- (void)attributedLabel:(TTTAttributedLabel *)label
didSelectLinkWithPhoneNumber:(NSString *)phoneNumber{
NSLog(@"phoneClick");
}
