iphone 开发之过滤html标签

过滤字符串中的html标签的方法：

[cpp]
- (NSString *)filterHtmlTag:(NSString *)originHtmlStr{
    NSString *result = nil;
    NSRange arrowTagStartRange = [originHtmlStr rangeOfString:@"<"];
    if (arrowTagStartRange.location != NSNotFound) { //如果找到
        NSRange arrowTagEndRange = [originHtmlStr rangeOfString:@">"];
//        NSLog(@"start-> %d   end-> %d", arrowTagStartRange.location, arrowTagEndRange.location);
//        NSString *arrowSubString = [originHtmlStr substringWithRange:NSMakeRange(arrowTagStartRange.location, arrowTagEndRange.location - arrowTagStartRange.location)];
        result = [originHtmlStr stringByReplacingCharactersInRange:NSMakeRange(arrowTagStartRange.location, arrowTagEndRange.location - arrowTagStartRange.location + 1) withString:@""];
       // NSLog(@"Result--->%@", result);
        return [self filterHtmlTag:result];    //递归，过滤下一个标签
    }else{
        result = [originHtmlStr stringByReplacingOccurrencesOfString:@" " withString:@""]; // 过滤等标签
        //result = [originHtmlStr stringByReplacingOccurrencesOf ........
    }
    return result;
}

- (NSString *)filterHtmlTag:(NSString *)originHtmlStr{
    NSString *result = nil;
    NSRange arrowTagStartRange = [originHtmlStr rangeOfString:@"<"];
    if (arrowTagStartRange.location != NSNotFound) { //如果找到
        NSRange arrowTagEndRange = [originHtmlStr rangeOfString:@">"];
//        NSLog(@"start-> %d   end-> %d", arrowTagStartRange.location, arrowTagEndRange.location);
//        NSString *arrowSubString = [originHtmlStr substringWithRange:NSMakeRange(arrowTagStartRange.location, arrowTagEndRange.location - arrowTagStartRange.location)];
        result = [originHtmlStr stringByReplacingCharactersInRange:NSMakeRange(arrowTagStartRange.location, arrowTagEndRange.location - arrowTagStartRange.location + 1) withString:@""];
       // NSLog(@"Result--->%@", result);
        return [self filterHtmlTag:result];    //递归，过滤下一个标签
    }else{
        result = [originHtmlStr stringByReplacingOccurrencesOfString:@" " withString:@""]; // 过滤等标签
        //result = [originHtmlStr stringByReplacingOccurrencesOf ........
    }
    return result;
}
