skpsmtpmessageを使用してplistファイルを正しく添付する方法は？

Question

私はskpsmtpmessageライブラリ経由でplistファイルを添付しようとするたびに、適切なそれぞれの名前で電子メールに表示されますが、サイズは0バイトです。ここで

-(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]; 
      /*

      @"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]; 

}

すべてのヘルプは非常に高く評価されています。ここでは、コードです！ :)

Answer 1

このため、（少なくとも）2つの考えられる原因があります。

NSData *crashData = [NSData dataWithContentsOfFile:filePath]; 

と

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

は最初のものは、あなたがディスクからファイルを読み取ることができない場合に失敗しても何らかの理由でbase64エンコーディングが失敗した場合、秒は失敗する可能性があります。これらのメソッドのいずれに対してもnil結果の検証を挿入して、エラーを適切に処理してください。
