iOS去掉字符串中的HTML标签的方法

方法一、NSScanner去除标签

 - (NSString *)removeTheHtmlFromString:(NSString *)htmlString {
     NSScanner * scanner = [NSScanner scannerWithString:htmlString];
     NSString * text = nil;
     while([scanner isAtEnd]==NO) {
         //找到标签的起始位置
         [scanner scanUpToString:@"<" intoString:nil];
         //找到标签的结束位置
         [scanner scanUpToString:@">" intoString:&text];
         //替换字符
         htmlString = [htmlString stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>",text] withString:@""];
     }
     return htmlString;
 }

方法二、正则方法

 //正则去除标签
 -(NSString *)removeHtmlWithString:(NSString *)htmlString{
     NSRegularExpression * regularExpretion=[NSRegularExpression regularExpressionWithPattern:@"<[^>]*>|\n" options: error:nil];
     htmlString = [regularExpretion stringByReplacingMatchesInString:htmlString options:NSMatchingReportProgress range:NSMakeRange(, htmlString.length) withTemplate:@""];
     return htmlString;
 }
