How to send an email to a receipent in background in iOS5?

Question

In an iPhone app,I want to send an email to a person who has forgotten about their passcode . I want to send the mail in background (cant use MFMailComposeViewController for this) and also the app must not be pushed to background . Is there a way to achieve this?

The best way of doing this is using SKPSMTPMessage. You can download it from here: https://github.com/jetseven/skpsmtpmessage This is a very easy solution that I have used before for using "Forgot Password" solutions in iOS apps. To implement simply drag the downloaded files into your application, #import the the "SKPSMTPMessage.h" into your class, and implement the following code:

.h

#import "SKPSMTPMessage.h"

@interface SomeView : UIViewController <SKPSMTPMessageDelegate> {

}

- (IBAction)forgotPassword;

.m

- (IBAction)forgotPassword {
SKPSMTPMessage *forgotPassword = [[SKPSMTPMessage alloc] init];
[forgotPassword setFromEmail:@"[email protected]"];  // Change to your email address
[forgotPassword setToEmail:@"[email protected]"]; // Load this, or have user enter this
[forgotPassword setRelayHost:@"smtp.gmail.com"];
[theMessage setRequiresAuth:YES]; // GMail requires this
[forgotPassword setLogin:@"[email protected]"]; // Same as the "setFromEmail:" email
[forgotPassword setPass:@"password"]; // Password for the Gmail account that you are sending from
[forgotPassword setSubject:@"Forgot Password: My App"]; // Change this to change the subject of the email
[forgotPassword setWantsSecure:YES]; // Gmail Requires this
[forgotPassword setDelegate:self]; // Required

NSString *newpassword = @"helloworld";

NSString *message = [NSString stringWithFormat:@"Your password has been successfully reset. Your new password: %@", newpassword];
NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain", kSKPSMTPPartContentTypeKey, message, kSKPSMTPPartMessageKey, @"8bit" , kSKPSMTPPartContentTransferEncodingKey, nil];

[forgotPassword setParts:[NSArray arrayWithObjects:plainPart, nil]];
[forgotPassword send];
}

Also be sure to include the following methods in the .m. You can change the contents of the UIAlertViews depending on what you want to display to the user.

- (void)messageSent:(SKPSMTPMessage *)message {
    NSLog(@"Message Sent");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Password Reset" message:@"Check your email for your new password." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
}

- (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error {
    NSLog(@"Message Failed With Error(s): %@", [error description]);
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"There was an error reseting your password. Please try again later." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
}

You also need to do the following before this will work. Your Target -> Get Info -> Build -> All Configurations -> Other Link Flags: "-ObjC" If you need help with this, see http://developer.apple.com/qa/qa2006/qa1490.html

EDIT: * CFNetwork.framework must also be added for this to work! *

Let me know if you have any more questions.

You can't use MFMailComposeViewController to do this. No API will allow you to send emails or any kind of message on behalf of the user without he seeing it.

The only I see is to make a call to your server and the server send the email, something like this:

NSURLRequest requestWithURL:[NSURL urlWithString:@"http://server.com/[email protected]"]];

You cannot send SMS/Email without user acceptance. But there are a lot of web-services in internet which can send SMS/Email. I guess some app uses those services or uses own.

Solution 4

You CAN send email in the background (without using the default MFMail Controller). BUT you still need the user to fill out whatever form (or content you want to email) and have them click "Send".

Here is my post on how to do it. It includes code and images.

Locking the Fields in MFMailComposeViewController

P.S. this works and Apple has approved over 10 of my apps that use this code/method.
