How to change message details (email body) in MFMailComposeViewController?

I seem to have fallen fowl of something that seems like it should be very simple!

How do I now populate an email's body with the strings a user has entered into NSUserDefaults?

Basically there is a button else ware that enters a sting such as 'YES' into NSUserDetaults. How do I make the email body those stored strings.

This is the code I currently have: 

- (IBAction)buttonPressed:(id)sender {
MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"SYS"];
[controller setMessageBody:@"How do I make this the content of NSUSERDEFAULTS?" isHTML:NO];
controller.navigationBar.barStyle = UIBarStyleBlack;
[self presentViewController:controller animated:YES completion:nil];

Any help would be greatly appreciated!

Thanks!

Using your code the strings appear as : Yes, No, Maybe, No way,

How can I alter the format to make them appear

Yes,

No,

Maybe,

No way.

Thanks again for your time!

What you want is a line break character, which can be achieved with \n (newline).

NSArray *storedStrings = [[NSUserDefaults standardUserDefaults] objectForKey:@"yourStoredKey"];
NSMutableString *messageBody = [NSMutableString string];
for (NSString *aString in storedStrings) {
    [messageBody appendFormat:@"%@,\n\n", aString];
}
[messageBody deleteCharactersInRange:NSMakeRange(messageBody.length-3, 3)];
[controller setMessageBody:messageBody isHTML:NO];

That line I added right after the for loop will remove the last three characters from the string, i.e. the two newline characters and the comma.

Try this method

- (IBAction)buttonPressed:(id)sender {
MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"SYS"];
[controller setMessageBody:[[nsstring stringwithformat@"%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"yourStoredKey"]]  isHTML:NO];
controller.navigationBar.barStyle = UIBarStyleBlack;
[self presentViewController:controller animated:YES completion:nil];
