iphone - 使用SMTP发送邮件后，应用崩溃

Question

在我的iPhone应用程序中，我使用SMTP来发送电子邮件。在发送邮件时，它们都能正常工作。但是有时在邮件发送后，应用突然崩溃，并显示以下错误消息

 <Warning>: Application 'UIKitApplication:com.myid.smtpsample[0x2630]' exited abnormally with signal 11: Segmentation fault: 11
��May  6 17:07:21 Device-3 ReportCrash[13041] <Error>: libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary

这是我的代码:

-(void) sendEmail
{
    NSData *imagedata=UIImageJPEGRepresentation(image, 0.2f);

    SKPSMTPMessage *Message = [[SKPSMTPMessage alloc] init];
    Message.fromEmail = @"my email";
    Message.toEmail = receiverEmailString;
    Message.relayHost = @"smtp.gmail.com";
    Message.requiresAuth = YES;
    Message.login = @"my email";
    Message.pass = @"my password";
    Message.subject = @"Details";
    Message.wantsSecure = YES; 
    Message.delegate = self;

    NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain",kSKPSMTPPartContentTypeKey,@"Message Body",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];

    NSDictionary *vcfPart= [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpeg;\r\n\tx-unix-mode=0644;\r\n\tname=\"MyPhoto.jpg\"",kSKPSMTPPartContentTypeKey,
                             @"attachment;\r\n\tfilename=\"MyPhoto.jpg\"",kSKPSMTPPartContentDispositionKey,[imagedata encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

    Message.parts = [NSArray arrayWithObjects:plainPart,vcfPart,nil];
    [Message send];

}


- (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error{

    NSLog(@"delegate - error(%d): %@", [error code], [error localizedDescription]);
}

- (void)messageSent:(SKPSMTPMessage *)message{

    NSLog(@"delegate - message sent");


}

请告诉我我在哪里做错了

我知道我回答这个问题有点晚了。但可能会帮助别人。所以去。

我遇到了同样的问题，这就是我解决的方法。我唯一要做的就是添加对SKPSMTPMessage对象的强引用，并在发送电子邮件时引用它。奇迹般有效。 (哦，我还保留了message = nil;，这对我来说没有任何问题。)

     @interface MyViewController ()    
     @property (nonatomic, strong) SKPSMTPMessage *Message;
     @end

    -(void) sendEmail
    {
        _Message = [[SKPSMTPMessage alloc] init];
        _Message.fromEmail = @"my email";
        _Message.toEmail = receiverEmailString;
        ...
        [_Message send];

    }


    - (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error{
        message = nil;
        NSLog(@"delegate - error(%d): %@", [error code], [error localizedDescription]);
    }

    - (void)messageSent:(SKPSMTPMessage *)message{    
        message = nil;
        NSLog(@"delegate - message sent"); 
    }

希望这可以帮助。
