TYAttributedLabel是一个强大的属性文本控件。它支持富文本、图文混排显示；它支持行间距、字间距、自适应高度、指定行数；它支持添加高度自定义文本属性，支持添加属性文本、自定义链接，新增高亮效果显示（文字和背景）；它还支持添加UIImage和UIView控件。
使用TYAttributedLabel实现字体大小、颜色各异并且带链接的文本：
//属性文本生成器
NSString* text = @"Not yet a Finnair Plus member?Learn more or sign up to start enjoying a world of benefits!";
TYTextContainer *textContainer = [[TYTextContainer alloc] init];
textContainer.text = text;
textContainer.textColor = [UIColor grayColor];
textContainer.font = [UIFont boldSystemFontOfSize:11];
textContainer.linesSpacing = 0.5;
//文字样式
TYTextStorage *textStorage = [[TYTextStorage alloc]init];
textStorage.range = [text rangeOfString:@"Learn more or sign up"];
textStorage.font = [UIFont boldSystemFontOfSize:11];
textStorage.textColor = [UIColor blueColor];
[textContainer addTextStorage:textStorage];
//下划线文字
TYLinkTextStorage *linkTextStorage = [[TYLinkTextStorage alloc]init];
linkTextStorage.range = [text rangeOfString:@"Learn more or sign up"];
linkTextStorage.linkData = @"登录芬兰航空";
//取消下划线
linkTextStorage.underLineStyle = kCTUnderlineStyleNone;
[textContainer addTextStorage:linkTextStorage];
TYAttributedLabel *label = [[TYAttributedLabel alloc]initWithFrame:CGRectMake(15, 350, KWidth-30, 0)];
label.backgroundColor = [UIColor clearColor];
label.textContainer = textContainer;
[label sizeToFit];
//设置代理
label.delegate = self;
[self.view addSubview:label];实现代理方法TYAttributedLabelDelegate：
//点击带链接文字“Learn more or sign up”
-(void)attributedLabel:(TYAttributedLabel *)attributedLabel textStorageClicked:(id<TYTextStorageProtocol>)textStorage atPoint:(CGPoint)point{
if ([textStorage isKindOfClass:[TYLinkTextStorage class]]){
NSString *linkStr = ((TYLinkTextStorage*)textStorage).linkData;
if ([linkStr isEqualToString:@"登录芬兰航空"]) {
[[ UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.finnair.com/cn/cn/plus"] options:@{} completionHandler:nil];
}
}
}
效果图：
