使用SKPSMTPMessage向多个收件人发送电子邮件？

Question

我需要在后台发送电子邮件,所以我必须使用名为SMTP的库.我使用的主要类是:SKPSMTPMessage.问题是"ccEmail",当我添加2个以上的收件人时,它无法发送电子邮件.(这需要很长的时间来委托方法).它适用于收件人<= 2.

smtpEmail.ccEmail = @"xyz@gmail.com, xyz1@gmail.com, xyz2@gmail.com";   

谁知道这个,请帮帮我.非常感谢 !

parseBuffer函数有我的更改:

case kSKPSMTPWaitingFromReply:
    {
        if ([tmpLine hasPrefix:@"250 "]) {

            if (!multipleRcptTo) {
                NSMutableString *multipleRcptToString = [NSMutableString string];
                [multipleRcptToString appendString:[self formatAddresses:toEmail]];
                [multipleRcptToString appendString:[self formatAddresses:ccEmail]];
                [multipleRcptToString appendString:[self formatAddresses:bccEmail]];

                multipleRcptTo = [[multipleRcptToString componentsSeparatedByString:@"\r\n"] mutableCopy];
                [multipleRcptTo removeLastObject];
            } 
            if ([multipleRcptTo count] > 0) {
                NSString *rcptTo = [NSString stringWithFormat:@"%@\r\n", [multipleRcptTo objectAtIndex:0]];
                [multipleRcptTo removeObjectAtIndex:0];

                //DEBUGLOG(@"C: %@", rcptTo);
                if (CFWriteStreamWriteFully((CFWriteStreamRef)outputStream, (const uint8_t *)[rcptTo UTF8String], [rcptTo lengthOfBytesUsingEncoding:NSUTF8StringEncoding]) < 0)
                {
                    error =  [outputStream streamError];
                    encounteredError = YES;
                }
                else
                {
                    [self startShortWatchdog];
                }
            } 
            if ([multipleRcptTo count] == 0) {
                sendState = kSKPSMTPWaitingToReply;

            }
        }
        break;
    }

并将其添加到标题中:

NSMutableArray *multipleRcptTo;

编辑:也改变以下方法,multipleRcptTo因为NSMutableString用作本地声明:

- (NSString *)formatAddresses:(NSString *)addresses {
  NSCharacterSet    *splitSet = [NSCharacterSet characterSetWithCharactersInString:@";,"];
  NSMutableString   *multipleRcpt = [NSMutableString string];

  if ((addresses != nil) && (![addresses isEqualToString:@""])) {
    if( [addresses rangeOfString:@";"].location != NSNotFound || [addresses rangeOfString:@","].location != NSNotFound ) {
        NSArray *addressParts = [addresses componentsSeparatedByCharactersInSet:splitSet];

        for( NSString *address in addressParts ) {
            [multipleRcpt appendString:[self formatAnAddress:address]];
        }
    }
    else {
        [multipleRcpt appendString:[self formatAnAddress:addresses]];
    }       
  }

  return(multipleRcpt);
}

SKPSMTPMessage 一次发送到SMTP地址,并且必须逐个发送.
