MFMailComposeViewController bringing up NSException - iphone

Question

I have done a search for this problem, and have not found an answer, which is leading me to write my firs tquestion here.
The problem is when I press the button which calls the metho below, I get an exception on this line: [self presentModalViewController:mailViewController animated:YES]; and the exception is:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCFString count]: unrecognized selector sent to instance 0x20f6c'
In addition, I am running my app on the simulator if that helps.
I got the magority of the code from here.
Here is my code (with the email address blanked out):
// set up the email address array
NSArray *email = [[NSArray alloc] initWithObjects:#"foo", nil];
// Set up the view controller
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
// Set up the email to send to
[mailViewController setSubject:#"foo"];
[mailViewController setToRecipients:[email objectAtIndex:0]];
// Get the path to the plist
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *path = [documentsPath stringByAppendingPathComponent:#"foo.plist"];
// Get the plist from the path
NSData *myData = [NSData dataWithContentsOfFile:path];
[mailViewController addAttachmentData:myData mimeType:#"plist" fileName:#"foo"];
// Fill out the email body text
NSString *emailBody = #"Attached PLIST file";
[mailViewController setMessageBody:emailBody isHTML:NO];
// Release the array
[email release];
if (mailViewController != nil) {
[self presentModalViewController:mailViewController animated:YES];
[mailViewController release];
}
What appears to be causing the exception?

Answer 1

In setToRecipients you have to specify an array, not a string. So you could pass your email-array.

Answer 2

-(IBAction)btnemail:(id)sender{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"subject"];
NSString *emailid=btnEmail.titleLabel.text;
NSArray *toRecipients = [NSArray arrayWithObject:emailid];
[picker setToRecipients:toRecipients];
NSString *emailBody = #"";
[picker setMessageBody:emailBody isHTML:NO];
if ([MFMailComposeViewController canSendMail]) {
[self.parentViewController presentModalViewController:picker animated:YES];
}else {
}
[picker release];
}
