iOS UILabel显示html标签

iOS7以后系统提供了显示html标签的方法

UIKIT_EXTERN NSString *const NSHTMLTextDocumentType NS_AVAILABLE_IOS(7_0);

直接上代码

NSString *str = @"<font color=\"#6c6c6c\">满20减5 满40减15，还剩<font color=\"#ff9147\">113天";

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(30, 50, 300, 50)];

NSAttributedString *attrStr = [[NSAttributedString alloc] initWithData:[str dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType} documentAttributes:nil error:nil];

label.attributedText = attrStr;

//如果想要改变文字的字体,请在设置attributedText之后设置

label.font = [UIFont systemFontOfSize:20];

[self.view addSubview:label];

代码效果
