how to create and attach CSV file in MFMailComposer in iPhone sdk? - iphone

Question

i have created one csv file and i am also attaching it to MFMailComposer and it shows me to my mail composer but when i send it to user email it does not shows me attached csv file in email. i have used this code to create csv file and adding data in it.
NSMutableString *mainString=[[NSMutableString alloc]initWithString:#""];
//NSMutableArray *section = [[NSMutableArray alloc] init];
for(int i = 0;i<[NameArray count];i++)
{
NSString *string=[indexArray objectAtIndex:i];
string=[string stringByReplacingOccurrencesOfString:#"\"" withString:#"\"\""];
[mainString appendFormat:#"\"%#\"",string];
string=[NameArray objectAtIndex:i];
string=[string stringByReplacingOccurrencesOfString:#"\"" withString:#"\"\""];
[mainString appendFormat:#",\"%#\"",string];
string=[typearray objectAtIndex:i];
string=[string stringByReplacingOccurrencesOfString:#"\"" withString:#"\"\""];
[mainString appendFormat:#",\"%#\"",string];
[mainString appendFormat:#",\"%#\"",string];
[mainString appendFormat:#"\n"];
}
NSLog(#"getdatafor csv:%#",mainString);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectoryPath stringByAppendingPathComponent:#"history.csv"];
// filePath = [filePath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSData* settingsData;
settingsData = [mainString dataUsingEncoding: NSASCIIStringEncoding];
NSError *error;
[settingsData writeToFile:filePath atomically:YES];
// NSLog(#"writeok");
NSData *mediaData = [NSData dataWithContentsOfFile:filePath options:NSDataReadingMapped error:&error];
NSLog(#"Length:%d Error:%#",[mediaData length],[error localizedDescription]);
here the above code is working good i am getting [mediaData length] i am attaching the CSV file from here.
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:#"history" ofType:#"csv"];
NSData *myData = [NSData dataWithContentsOfFile:path];
// Fill out the email body text
NSString *emailBody = #"history";
[picker setMessageBody:emailBody isHTML:NO];
[picker addAttachmentData:myData mimeType:#"text/cvs" fileName:#"history"];
[self presentModalViewController:picker animated:YES];
[picker release];
the above code is also working properly. it shows me attached CSV file but when i am sending the mail by email at that time receiver is not getting the attached CSV file. what's wrong in this code.? why the receiver is not getting the attached file.?

Answer 1

MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"CSV File"];
NSData *myData = [text dataUsingEncoding:NSUTF8StringEncoding];
[mailer addAttachmentData:myData mimeType:#"text/cvs" fileName:#"FileName"];
[self presentModalViewController:mailer animated:YES];
Where the 'text' is a string.
