Question

I am developing an application, i want to know how to achive forget password scenario in iPhone.

When user forget their password then I have a button in my app when i click on it UIAlertView open in which i have a textfield, user must enter their email address and the password get mail on that mail id.

How can I do that I have define a action for button this is the code:

-(IBAction)forgetpassword:(id)sender
{
    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Forget Password" message:@"Please Enter your Email address " delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
    av.alertViewStyle = UIAlertViewStylePlainTextInput;
    [av textFieldAtIndex:0].delegate = self;
    [av show];
}

but what i need is just require the code to which i can use and mail the password to the email id which user will entered.

Answer 1

just add delegate MFMessageComposeViewControllerDelegate to the .h file and then use this code when you want to email and also add framework MessageUI.framework in the project

-(IBAction)forgetpassword:(id)sender
{
     if ([MFMailComposeViewController canSendMail]) 
     {

        MFMailComposeViewController *mailComposeViewController = [[MFMailComposeViewController alloc] init];
        NSString *mailBody = @"your Message";


        [mailComposeViewController setMessageBody:mailBody isHTML:NO];
        mailComposeViewController.mailComposeDelegate = self;
        [self presentViewController:mailComposeViewController animated:YES completion:nil];
    } 
    else 
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"e-Mail Sending Alert"
                                                        message:@"You can't send a mail"
                                                       delegate:nil
                                              cancelButtonTitle:@"OK" 
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
}

and this bellow method is delegate method of MFMessageComposeViewControllerDelegate

#pragma mark - MFMessage Delegate

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    if (result == MFMailComposeResultSent) 
    {
        NSLog(@"\n\n Email Sent");
    }
    [self dismissViewControllerAnimated:YES completion:nil];
}

you can also use SKPSMTPmessage web-service for send e-mail

i hope this help you…
