CSV not attaching to in app email?

Question

So I have had this problem for sometime and just cant get it working! I have been building a survey app that users simply enter information in and its saved to a csv file. Im no

Answer 1

Reason for csv not being attached can be ether of below :

1) filename or filepath is wrong as result nsdata of csv will be nil.

2) filename in addAttachmentData mimeType: fileName: method should cantain only name not type of file format.

Changes in your method is given below :

-(IBAction)send:(id)sender {

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    // Determine the file name and extension
    NSString *strFileName = @"results.csv";
    NSArray *filepart = [strFileName componentsSeparatedByString:@"."];
    NSString *filename = [filepart objectAtIndex:0];

    //get file path
    NSString *savedFilePath = [documentsDirectory stringByAppendingPathComponent:strFileName];

    //Now check if file exits
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:savedFilePath]){ 
       NSData *csvData = [NSData dataWithContentsOfFile:savedFilePath];

       if(csvData)
       {
          MFMailComposeViewController *mailcomposer = [[MFMailComposeViewController alloc] init];
          [mailcomposer addAttachmentData:csvData mimeType:@"text/csv" fileName:filename];
          [mailcomposer setToRecipients:@[@"gpsflighttrial@gcap.eu"]];
          [mailcomposer setSubject:self.subject.text];
          [mailcomposer setMessageBody:self.message.text isHTML:NO];
       }
       else
          NSLog(@"error csv data not created");
    }
    else
       NSLog(@"error file doesnot exists");

}
