    <p>The code below works perfectly to send text (.txt) attachments via the mail application (textfile.csv needs to be modified everywhere with textfile.txt). However when I try to attach csv files it does not work at all (the mail application opens up showing the icon of the textfile.csv but when the mail arrives it has no attachment (nor the data is displayed within the message body). No difference if I change the mime type to "text/plain". I am puzzled... What am I doing wrong?? Any ideas please?</p> <pre><code> - (NSString *)getPath { NSString *paths = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; return [paths stringByAppendingPathComponent:@"textfile.csv"]; } //Saves file to Documents folder //Method writes a string to a text file -(void) writeToTextFile{ //get the documents directory: NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; //make a file name to write the data to using the documents directory: NSString *fileName = [NSString stringWithFormat:@"textfile.csv", documentsDirectory]; //create content NSString *content = @"One,Two,Three,Four,Five"; //save content to the documents directory [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; } // Displays an email composition interface inside the application. Populates all the Mail fields. -(void)displayComposerSheet { MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject:@"Subject"]; // Set up recipients NSArray *toRecipients = [NSArray arrayWithObject:@"email@domain.com"]; [picker setToRecipients:toRecipients]; // Fill out the email body text NSString *emailBody = (@"Data is attached as a .CSV file"); [picker setMessageBody:emailBody isHTML:NO]; NSString *SavedDataPath = [self getPath]; NSString *path = SavedDataPath; NSData *myData = [NSData dataWithContentsOfFile:path]; [picker addAttachmentData:myData mimeType:@"text/csv" fileName:@"textfile.csv"]; [self presentModalViewController:picker animated:YES]; [picker release]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
