Question

每次我尝试通过skpsmtpmessage库附加plist文件时，它们都会在电子邮件中显示其正确的相应名称，但大小为0字节。这是代码：

-(void) sendMessage{

NSLog(@"Start Sending");

SKPSMTPMessage *test_smtp_message = [[SKPSMTPMessage alloc] init];
test_smtp_message.fromEmail = @"jaredloo@live.com.sg";
test_smtp_message.toEmail = @"vest@un0wn.org";
test_smtp_message.relayHost = @"smtp.live.com";
test_smtp_message.requiresAuth = YES;
test_smtp_message.login = @"jaredloo@live.com.sg";
test_smtp_message.pass = @"blabla";
test_smtp_message.wantsSecure = YES; // smtp.gmail.com doesn't work without TLS!
test_smtp_message.subject = @"An application has crashed!";




//    test_smtp_message.bccEmail = @"testbcc@test.com";

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

NSMutableArray *parts_to_send = [NSMutableArray array];

//If you are not sure how to format your message part, send an email to your self.  
//In Mail.app, View > Message> Raw Source to see the raw text that a standard email client will generate.
//This should give you an idea of the proper format and options you need
    /*NSDictionary *plain_text_part = [NSDictionary dictionaryWithObjectsAndKeys:
                                     @"text/plain\r\n\tcharset=UTF-8;\r\n\tformat=flowed", kSKPSMTPPartContentTypeKey,
                                     [@"Sample message body here!" stringByAppendingString:@"\n"], kSKPSMTPPartMessageKey,
                                     @"quoted-printable", kSKPSMTPPartContentTransferEncodingKey,
                                     nil];
    [parts_to_send addObject:plain_text_part];*/



    //NSString *image_path = [[NSBundle mainBundle] pathForResource:@"Success" ofType:@"png"];
    NSArray *crashList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:@"/User/Library/Logs/CrashReporter" error:nil];
    NSLog(@"CrashList: %@", crashList);
    if ([crashList count] != 0)
    {
        for (int i=0; i < [crashList count]; i++) {
            NSString *filePath = [NSString stringWithFormat:@"/User/Library/Logs/CrashReporter/%@",[crashList objectAtIndex:i]];
            NSData *crashData = [NSData dataWithContentsOfFile:filePath]; 
            NSString *directory = @"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"";
            directory = [directory stringByAppendingFormat: filePath];
            directory = [directory stringByAppendingFormat: @"\""];
            NSString *attachment = @"attachment;\r\n\tfilename=\"";
            attachment = [attachment stringByAppendingFormat: filePath];
            attachment = [attachment stringByAppendingFormat: @"\""];
            NSDictionary *image_part = [NSDictionary dictionaryWithObjectsAndKeys:
                                        directory,kSKPSMTPPartContentTypeKey,
                                        attachment,kSKPSMTPPartContentDispositionKey,
                                        [crashData encodeBase64ForData],kSKPSMTPPartMessageKey,
                                        @"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
            /*
             [NSDictionary dictionaryWithObjectsAndKeys:
             @"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.vcf\"",kSKPSMTPPartContentTypeKey,
             @"attachment;\r\n\tfilename=\"test.vcf\"",kSKPSMTPPartContentDispositionKey,
             [vcard_data encodeBase64ForData],kSKPSMTPPartMessageKey,
             @"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

            */
            [parts_to_send addObject:image_part];
        }
    }

test_smtp_message.parts = parts_to_send;

[test_smtp_message send];

}

这是电子邮件（在vest@un0wn.org一侧）[GMAIL]

非常感谢任何帮助！：）

至少有两个可能的原因：

 NSData *crashData = [NSData dataWithContentsOfFile:filePath];

和

 ...
 [crashData encodeBase64ForData],kSKPSMTPPartMessageKey, 
 ...

如果您无法从磁盘读取文件，则第一个可能会失败，如果您的base64编码由于某种原因失败，则第二个可能会失败。尝试为这些方法中的任何一种插入nil结果的验证并正确处理错误。

如何使用skpsmtpmessage正确附加plist文件？
