Send mail to an array list recipients from a database in ObjectiveC - objective-c

Question

I am using ObjectiveC and I want to send an email to a list of email addresses that I have in a sqlite database. The email array hold the addresses that I want to send the mail to.
I show you my code
- (void)sendEmailButtonClicked: (id)sender {
// Email Subject
NSString *emailTitle = #"Test Email";
// Email Content
NSString *messageBody = #"iOS programming is so fun!";
// To address
NSArray *toRecipents = [NSArray arrayWithObject:emailArray];
NSLog(#"What are the emais %#",toRecipents);
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setToRecipients:toRecipents];
[mc setMessageBody:messageBody isHTML:NO];
// Present mail view controller on screen
[self presentViewController:mc animated:YES completion:NULL];
}
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(#"Mail cancelled");
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved");
break;
case MFMailComposeResultSent:
NSLog(#"Mail sent");
break;
case MFMailComposeResultFailed:
NSLog(#"Mail sent failure: %#", [error localizedDescription]);
break;
default:
break;
}
// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];
}
I obtain this error: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM mf_isLegalCommentedEmailAddress]: unrecognized selector sent to instance 0x78e5e180'
Anyone can help me please? Thank you so much!

Answer 1

First of all it should be:
NSArray *toRecipents = [NSArray arrayWithArray:emailArray];
But why not just do:
[mc setToRecipients:emailArray];
Assuming email array is a valid array object as we can't see from your code where/how you create it.
EDIT
You likely can't send an email from the simulator if there isn't an email account setup. Check for this with the following:
if ([MFMailComposeViewController canSendMail]) {
//Do your email stuff
}
else {
//Present an error etc ...
}

There's an issue with your array. This code works fine when sending to multiple recipients:
//Email
-(void)mailButton {
NSArray *emailArray = #[#"me#gmail.com", #"you#gmail.com", #"him#gmail.com", #"her#gmail.com", #"everyone#gmail.com"];
if ([MFMailComposeViewController canSendMail]) {
NSString *subject = #"Subject";
NSString *messageBody = [NSString stringWithFormat:#"Message Body"];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:subject];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:emailArray];
[self presentViewController:mc animated:YES completion:NULL];
}
else {
UIAlertView *emailError = [[UIAlertView alloc] initWithTitle:#"Email Unavailable"
message:#"Sorry, were unable to find an email account on your device.\nPlease setup an account in your devices settings and try again."
delegate:self
cancelButtonTitle:#"Close"
otherButtonTitles:nil];
[emailError show];
}
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
switch (result) {
case MFMailComposeResultCancelled:
break;
case MFMailComposeResultSaved:
break;
case MFMailComposeResultSent:
break;
case MFMailComposeResultFailed:
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:NULL];
}

Answer 3

toRecipents should be an array, which contains only one email address.
As below,
toRecipents = #[#"foo#example.com"];
If, you want to send email some people, you should use setCcRecipients method.
