ios版：

const char* IosHelper::removeEmoji(const char* str){    std::string strLen = str;    Nsstring* username = [[Nsstring alloc] initWithBytes:str length:strLen.length() enCoding:NSUTF8StringEnCoding];    cocos2d::log("IosHelper::removeEmoji username0 = %s",str);    NSLog(@"IosHelper::removeEmoji username1 = %@",username);    //Nsstring *regex = @"^[a-zA-Z0-9_\u4e00-\u9fa5]+$";    Nsstring *regex = @"[\u0020-\u007e\u4e00-\u9fa5]";    //Nsstring *regex = @"^[a-zA-Z\u4e00-\u9fa5]+";    nspredicate *predicate = [nspredicate predicateWithFormat:@"SELF MATCHES %@",regex];    Nsstring *temp = nil;    //NSLog(@"IosHelper::removeEmoji username = %d",[username length]);    for(int i = 0; i < [username length]; i++)    {        temp = [username substringWithRange:NSMakeRange(i,1)];        //NSLog(@"i = %d char = %x str = %@",i,temp,temp);        if ([predicate evaluateWithObject:temp]) {            //NSLog(@"This character is OK");        } else {            NSRange range = NSMakeRange(i,1);            username = [username stringByReplacingCharactersInRange:range withString:@" "];        }    }        Nsstring *withoutEmojiUsername = [username stringByReplacingOccurrencesOfString:@" " withString:@""];    NSLog(@"IosHelper::removeEmoji username2 = %@",withoutEmojiUsername);    const char* retStr = [withoutEmojiUsername UTF8String];    cocos2d::log("IosHelper::removeEmoji username3 = %s",retStr);    return retStr;}
