I have made a pdf file and I am trying to attach it with the email but the file doesn't get attached infact the file name isn't what, what it is suppose to be. Following is my code
- (IBAction)btnAttachPDF:(id)sender {
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"video"];
NSArray *toRecipients = [NSArray arrayWithObjects:#"", nil];
[mailer setToRecipients:toRecipients];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *fileName;
fileName = [[NSString alloc]initWithFormat:#"%#.pdf", lblName.text];
lblName.text suppose to returns me the file name which i have entered but it is just .pdf but if I give it a hardcoded value it does stores the name of the file lets say I gave it a name #"rio.pdf" but later on the file doesn't get attached.
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
NSMutableData *myPdfData = [NSMutableData dataWithContentsOfFile:pdfFileName];
[mailer addAttachmentData:myPdfData mimeType:#"application/pdf" fileName:fileName];
[self presentViewController:mailer animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Failure"
message:#"Your device doesn't support the composer sheet"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
Actually the path returned by NSSearchPathForDirectoriesInDomains isn't the exact one. The last component it was returning was /Documents whereas, the files were being saved in /Documents/temp/filename.pdf

This is for my iOS app using Core Data.
I'm getting some extra information in my CSV export that I'd like to remove. Below is my code and an example of what I am seeing.
Code:
NSOutputStream *stream = [[NSOutputStream alloc] initToMemory];
CHCSVWriter *writer = [[CHCSVWriter alloc] initWithOutputStream:stream encoding:NSUTF8StringEncoding delimiter:','];
NSManagedObjectContext *managedObjectContext = [self managedObjectContext];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:#"Notes"];
self.fetchedObjects = [managedObjectContext executeFetchRequest:fetchRequest error:nil];
for (NSString *instance in self.fetchedObjects) {
[writer writeLineOfFields:#[instance.description]];
}
[writer closeStream];
NSData *buffer = [stream propertyForKey:NSStreamDataWrittenToMemoryStreamKey];
NSString *output = [[NSString alloc] initWithData:buffer encoding:NSUTF8StringEncoding];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
NSString * csvPath = [documentsDirectory stringByAppendingPathComponent:#"mydata.csv"];
if ([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController * mailView = [[MFMailComposeViewController alloc] init];
mailView.mailComposeDelegate = self;
[[mailView navigationBar] setTintColor:[UIColor whiteColor]];
[mailView setSubject:#"My Subject Line"];
if (![[NSFileManager defaultManager] fileExistsAtPath:csvPath]) {
[[NSFileManager defaultManager] createFileAtPath:csvPath contents:nil attributes:nil];
}
BOOL res = [[output dataUsingEncoding:NSUTF8StringEncoding] writeToFile:csvPath atomically:NO];
if (!res) {
[[[UIAlertView alloc] initWithTitle:#"Error Creating CSV" message:#"Check your permissions to make sure this app can create files so you may email the app data" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles: nil] show];
} else{
NSLog(#"Data saved! File path = %#", csvPath);
[mailView addAttachmentData:[NSData dataWithContentsOfFile:csvPath] mimeType:#"text/csv" fileName:#"mydata.csv"];
[self presentViewController:mailView animated:YES completion:nil];
}
} else {
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"Mail Error" message:#"Your device is not configured to send mail." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
Output Example:
<Notes: 0x1c009fb30> (entity: Notes; id: 0xd000000000080000 <x-coredata://597EDC54-FFDE-43FA-8C61-DE67763C1D13/Notes/p2> ; data: {
// My data shows here.
})
What I want:
I just want the saved data from the user input. Not the extra data about the entity, id, etc.
Also:
My data does not load in the email initially. I have to go into my UIViewController and then when I go to my Settings page and send the email the data shows. What would cause this?
You're getting that result because you're relying the description method to get information about your objects. That method produces a string, and the string is what you're seeing-- something that's not CSV, or easy to convert to CSV.
I'm not familiar with CHCSVParser but it looks like you might want to override description in your Notes class to produce something that CHCSVParser can handle. The default implementation on NSManagedObject-- which is what you're using now-- is not a good choice for this situation.
I am trying to generate a text file and attach it to email. Previously I used this code to attach the file to email and it is done successfully.
NSString *recipient = #"myemail#me.com";
NSArray *recipients = [NSArray arrayWithObjects:recipient, nil];
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setSubject:#"Invalid Scan"];
[mailViewController setToRecipients:recipients];
[mailViewController setMessageBody:#"" isHTML:NO];
mailViewController.navigationBar.tintColor = [UIColor blackColor];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *textFilePath = [documentsDirectory stringByAppendingFormat:#"/textfile.txt"];
NSData *myData = [NSData dataWithContentsOfFile:textFilePath];
// NSLog(#"my nsdata is %#",myData);
[mailViewController addAttachmentData:myData
mimeType:#"text/csv"
fileName:textfile.txt];
But when I tried to use this statement below ,the file didn't get attached :
NSString *fileName_txtFile= #"textfile.txt";
NSString *textFilePath = [documentsDirectory stringByAppendingFormat:[NSString stringWithFormat:#"/%#",fileName_txtFile],nil];
NSData *myData = [NSData dataWithContentsOfFile:textFilePath];
[mailViewController addAttachmentData:myData
mimeType:#"text/csv"
fileName:fileName_txtFile];
I couldn't figure out, why the file is not attaching to the mail. Could you please help me in this issue?
Thanks in advance!!
I'm using the following code to attach a csv file that is generated to mail composer.
NSString *recipient = #"tejanvm92#gmail.com";
NSArray *recipients = [NSArray arrayWithObjects:recipient, nil];
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setSubject:#"CSV Export"];
[mailViewController setToRecipients:recipients];
[mailViewController setMessageBody:#"" isHTML:NO];
mailViewController.navigationBar.tintColor = [UIColor blackColor];
NSData *myData = [NSData dataWithContentsOfFile:#"yourFileName.csv"];
[mailViewController addAttachmentData:myData
mimeType:#"text/csv"
fileName:#"yourFileName"];
[self presentModalViewController:mailViewController animated:YES];
When the code runs.....the csv file is not attached to the mail properly.
But When I got the mail, it is empty. Could you please help me in finding the issue?
[NSData dataWithContentsOfFile:#"yourFileName.csv"]// its wrong way.
Please write full path of csv file
Like if your csv file in Documents directory.
then
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *csvFilePath = [documentsDirectory stringByAppendingFormat:#"/yourFileName.csv"];
after that change in your code
[NSData dataWithContentsOfFile:csvFilePath];
I can send a .csv file as an attachment from my app, but I'd like to shorten the name file for that attachment, because there will be a pile of csv files delivered to the recipient.
Piece of code:
...
if (dorsalesPorTramoYcontrol && dorsalesPorTramoYcontrol.count )
{
NSMutableString *mainString = [[ NSMutableString alloc]initWithString:#"dorsal,paso,tiempo\n"];
for (NSManagedObject *get in dorsalesPorTramoYcontrol) {
//dorsales
NSString *string =[get valueForKey:#"dorsal"];
[mainString appendFormat:#"%#,",string];
//paso
string = [get valueForKey:#"paso"];
string=[string stringByReplacingOccurrencesOfString:#"\"" withString:#"\"\""];
[mainString appendFormat:#"%#,",string];
//tiempo
string = [get valueForKey:#"tiempo"];
string=[string stringByReplacingOccurrencesOfString:#"\"" withString:#"\"\""];
[mainString appendFormat:#"%#",string];
[mainString appendFormat:#"\n"];
}
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
file = [NSString stringWithFormat:#"%#/Tramo%#Control%#.csv", documentsDirectoryPath,section,control];
NSError *csVerror= NULL;
BOOL written = [mainString writeToFile:file atomically:YES encoding:NSUTF8StringEncoding error:&csVerror];
if (!written) {
NSLog( #"Writing failed, error = %#",csVerror);
}else {
NSLog(#"Data saved! File path = %#",file);
[self composeEmail];
}
}
}
-(void)composeEmail{
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:[NSString stringWithFormat:#"Resultados Tramo: %# - Control: %#", section, control]];
NSArray *toRecipients = [NSArray arrayWithObjects:#"somebodymail#mail.com", nil];
[mailer setToRecipients:toRecipients];
// Logo
UIImage *myImage = [UIImage imageNamed:#"logo.png"];
NSData *imageData = UIImagePNGRepresentation(myImage);
[mailer addAttachmentData:imageData mimeType:#"image/png" fileName:#"Icon"];
[mailer addAttachmentData:[NSData dataWithContentsOfFile:file] mimeType:#"text/csv" fileName:file];
NSString *emailBody =
[NSString stringWithFormat:#"Resultados Tramo: %# - Control: %# \nDorsal - Paso - Tiempo", section, control];
[mailer setMessageBody:emailBody isHTML:NO];
mailer.modalPresentationStyle = UIModalPresentationPageSheet;
[self presentViewController:mailer animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Failure"
message:#"Your device doesn't support the composer sheet"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alert show];
}
}
The filename is the following:
<_var_mobile_Applications_BE8CE610-A83E-4C79-8B9C-0263FA6881D6_Documents_Tramo2Control4.csv>
and I'd like it to be just "Tramo2Control4.csv"
Could you please offer some suggestions to get it?
Change the following line:
[mailer addAttachmentData:[NSData dataWithContentsOfFile:file] mimeType:#"text/csv" fileName:file];
To:
NSString *fileName = [file lastPathComponent];
[mailer addAttachmentData:[NSData dataWithContentsOfFile:file] mimeType:#"text/csv" fileName:fileName];
You were originally setting the file name to be the entire file path.
I would like to create a file using a NSString (already made) with a .csv extension then email it using the UIMessage framework. So can someone show me the code to create a file (with a .csv extensions and with the contents of a NSString) then how to attach it to a MFMailComposeViewController.
This is how you attach a CSV file to a MFMailComposeViewController:
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"CSV File"];
[mailer addAttachmentData:[NSData dataWithContentsOfFile:#"PathToFile.csv"]
mimeType:#"text/csv"
fileName:#"FileName.csv"];
[self presentModalViewController:mailer animated:YES];
// Note: PathToFile.csv is the actual path of the file on your iOS device's
// file system. FileName.csv is what it should be displayed as in the email.
As far as how to generate the CSV file itself, the CHCSVWriter class at https://github.com/davedelong/CHCSVParser will help you.
Here are the parts where you create a new csv, save it to file and attach it all in one. You know, if you're in to that sort of thing
NSString *emailTitle = #"My Email Title";
NSString *messageBody = #"Email Body";
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:#[]];
NSMutableString *csv = [NSMutableString stringWithString:#""];
//add your content to the csv
[csv appendFormat:#"MY DATA YADA YADA"];
NSString* filePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* fileName = #"MyCSVFileName.csv";
NSString* fileAtPath = [filePath stringByAppendingPathComponent:fileName];
if (![[NSFileManager defaultManager] fileExistsAtPath:fileAtPath]) {
[[NSFileManager defaultManager] createFileAtPath:fileAtPath contents:nil attributes:nil];
}
BOOL res = [[csv dataUsingEncoding:NSUTF8StringEncoding] writeToFile:fileAtPath atomically:NO];
if (!res) {
[[[UIAlertView alloc] initWithTitle:#"Error Creating CSV" message:#"Check your permissions to make sure this app can create files so you may email the app data" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles: nil] show];
}else{
NSLog(#"Data saved! File path = %#", fileName);
[mc addAttachmentData:[NSData dataWithContentsOfFile:fileAtPath]
mimeType:#"text/csv"
fileName:#"MyCSVFileName.csv"];
[self presentViewController:mc animated:YES completion:nil];
}
