Iphone 使用SMTPSender/SKPSMTPMessage发送电子邮件时出现错误-[nsconcertemutabledata encodeBase64ForData]：无法识别的选择器发送到实例0x6a67190

我花了两天时间来实现这一点，但没有成功。我正在使用SMTPSender项目代码。。。演示项目工作完美！ 但是，当我将类文件复制到我的项目中时（如说明中所示），它构建并运行良好。但是当我尝试发送电子邮件时。。。它给出了以下错误

我的代码是

SKPSMTPMessage *testMsg = [[SKPSMTPMessage alloc] init];
testMsg.fromEmail = @"mygmail@gmail.com";
testMsg.toEmail = @"myanothergmail@gmail.com";
testMsg.relayHost = @"smtp.gmail.com";
testMsg.requiresAuth = YES;
testMsg.login = @"mygmail@gmail.com";
testMsg.pass = @"mypass";
testMsg.subject = @"test message";
    //   testMsg.bccEmail = @"testbcc@test.com";
testMsg.wantsSecure = YES; // smtp.gmail.com doesn't work without TLS!

// Only do this for self-signed certs!
// testMsg.validateSSLChain = NO;
testMsg.delegate = self;

NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain",kSKPSMTPPartContentTypeKey,
                           @"This is a test message.",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];

testMsg.parts = [NSArray arrayWithObjects:plainPart,nil];

[testMsg send];

请帮帮我（

我第一次使用SKPSMTPMessage时遇到了这个问题。我忘记了细节，也忘了从哪里得到原始答案，但我将NSStream+SKPSMTPExtensions.*包装到SKPSMTPMessage.*中，它就消失了

只需将接口和实现放在导入之后，放在NSStream（SKPSMTPExtensions）的其余代码之前
