使用GTLGmail类iOS发送新电子邮件

我正在开发gmail应用程序，我想用它发送一封新的电子邮件

我知道我们必须进行如下查询：-

GTLQueryGmail *query = [GTLQueryGmailqueryForUsersMessagesSendWithUploadParameters:nil];
query.message = gtlGmailMessage; //parent message
[self.service executeQuery:query
              delegate:self
     didFinishSelector:@selector(displayResult:finishedWithObject:error:)];

但我无法理解如何在查询中传递gtlGmailMessage消息

i、 e

任何人都可以告诉在哪里输入有效载荷数据，如何设置到字段和从字段

提前感谢。

以下是我如何将邮件作为原始数据发送的方法：

已被弃用，它已被替换为

NSString*messageString=@“发件人：\”发件人电子邮件用户名\“\r\n”；
messageString=[messageString stringByAppendingString:@“To:\”到电子邮件用户名\“\r\n”]；
messageString=[messageString stringByAppendingString:@“主题：新内容\r\n”]；
messageString=[messageString stringByAppendingString:@“内容类型：text/html；charset=iso-8859-1\r\n\r\n”]；
messageString=[messageString stringByAppendingString:@“你好，我的朋友，\n有空时请给我打电话。\n标记。”；
NSData*data=[messageString dataUsingEncoding:NSUTF8StringEncoding]；
NSString*base64Encoded=GTLREncodeWebSafeBase64（数据）；
GTLRGmail_Message*Message=[[GTLRGmail_Message alloc]init]；
message.raw=base64Encoded；
GTLRGmailQuery_usersmessagesend*query=[GTLRGmailQuery_usersmessagesend querywhithobject:message userId:@“myEmailAddress”uploadParameters:nil]；
[self.service executeQuery:query completionHandler:^（GTLRServiceTicket*\u非空callbackTicket，id\u可空对象，NSError*\u可空callbackError）{
NSLog（@“%@”，回调错误）；
}];

 GTLGmailMessage *gtlGmailMessage = [[GTLGmailMessage alloc] init];

NSString *messageString =                              @"From: \"From Email USer Name\" <fromEmail>\r\n";
messageString = [messageString stringByAppendingString:@"To: \"To Email User Name\" <ToEmail>\r\n"];
messageString = [messageString stringByAppendingString:@"Subject: New stuff\r\n"];
messageString = [messageString stringByAppendingString:@"Content-type: text/html;charset=iso-8859-1\r\n\r\n"];
messageString = [messageString stringByAppendingString:@"Hello my friend, \n can you please call me when have free time. \nMark."];

NSData *data = [messageString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64Encoded = GTLREncodeWebSafeBase64(data);


GTLRGmail_Message *message = [[GTLRGmail_Message alloc] init];

message.raw = base64Encoded;

GTLRGmailQuery_UsersMessagesSend *query = [GTLRGmailQuery_UsersMessagesSend queryWithObject:message userId:@"myEmailAddress" uploadParameters:nil];

[self.service executeQuery:query completionHandler:^(GTLRServiceTicket * _Nonnull callbackTicket, id  _Nullable object, NSError * _Nullable callbackError) {
      NSLog(@"%@",callbackError);
 }];
