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:#"some-email#gmail.com"]; // Change to your email address
[forgotPassword setToEmail:#"user-email#gmail.com"]; // Load this, or have user enter this
[forgotPassword setRelayHost:#"smtp.gmail.com"];
[theMessage setRequiresAuth:YES]; // GMail requires this
[forgotPassword setLogin:#"some-email#gmail.com"]; // 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.
Thanks,

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/send_passcode?to=email#lala.com"]];
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.
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.
In reference to the PostageApp comment below if you wanted to send emails without any hassle of setting up an SMTP client you can check out the PostageKit wrapper for using the PostageApp service. Let's you send emails with a couple lines of code reliably.

May be you should implement PHP script that will send out email to user. In ios, you can use POST method in NSURLConnection to call PHP script. You can find many scripts on Google to send out email to user.
Download SKPSMTP Library and import
#import "SKPSMTPMessage.h"
#import "NSData+Base64Additions.h"
-(IBAction)btnRecoverClicked:(id)Sender;
Then implement the method for sending mail in background.
-(IBAction) btnRecoverClicked:(id)sender {
NSString *str=#"Your password is:";
NSString *strUserPassword=[NSString stringWithFormat:#"%# %#",str,struserPassword];
NSLog(#"Start Sending");
SKPSMTPMessage *emailMessage = [[SKPSMTPMessage alloc] init];
emailMessage.fromEmail = #"XXXXX"; //sender email address
emailMessage.toEmail = struserEmail; //receiver email address
emailMessage.relayHost = #"smtp.gmail.com";
//emailMessage.ccEmail =#"your cc address";
//emailMessage.bccEmail =#"your bcc address";
emailMessage.requiresAuth = YES;
emailMessage.login = #"xxxxxxxx"; //sender email address
emailMessage.pass = #"XXXXXXX"; //sender email password
emailMessage.subject =#"Password Recovery";
emailMessage.wantsSecure = YES;
emailMessage.delegate = self; // you must include <SKPSMTPMessageDelegate> to your class
NSString *messageBody = [NSString stringWithFormat:#"Your password is: %#",struserPassword]
;
//for example : NSString *messageBody = [NSString stringWithFormat:#"Tour Name: %#\nName: %#\nEmail: %#\nContact No: %#\nAddress: %#\nNote: %#",selectedTour,nameField.text,emailField.text,foneField.text,addField.text,txtView.text];
// Now creating plain text email message
NSDictionary *plainMsg = [NSDictionary
dictionaryWithObjectsAndKeys:#"text/plain",kSKPSMTPPartContentTypeKey,
messageBody,kSKPSMTPPartMessageKey,#"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];
emailMessage.parts = [NSArray arrayWithObjects:plainMsg,nil];
//in addition : Logic for attaching file with email message.
/*
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"filename" ofType:#"JPG"];
NSData *fileData = [NSData dataWithContentsOfFile:filePath];
NSDictionary *fileMsg = [NSDictionary dictionaryWithObjectsAndKeys:#"text/directory;\r\n\tx-
unix-mode=0644;\r\n\tname=\"filename.JPG\"",kSKPSMTPPartContentTypeKey,#"attachment;\r\n\tfilename=\"filename.JPG\"",kSKPSMTPPartContentDispositionKey,[fileData encodeBase64ForData],kSKPSMTPPartMessageKey,#"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
emailMessage.parts = [NSArray arrayWithObjects:plainMsg,fileMsg,nil]; //including plain msg and attached file msg
*/
[emailMessage send];
// sending email- will take little time to send so its better to use indicator with message showing sending...
}
To handle the success and fail use
-(void)messageSent:(SKPSMTPMessage *)message{
NSLog(#"delegate - message sent");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Message sent to your mail." message:nil delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles: nil];
[alert show];
}
and
-(void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error{
// open an alert with just an OK button
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error!" message:[error localizedDescription] delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles: nil];
[alert show];
NSLog(#"delegate - error(%d): %#", [error code], [error localizedDescription]);
}

I have used library above to send mail in background, so it works.
pod "MailUtil", :git => 'https://github.com/troyz/MailUtil.git', :tag => '0.1.0'
Swift code is here:
import MailUtil
SendEmailOperation.setupConfig(withServer: "smtp.foo.com", withFrom: "foo#mailserver.com", withLogin: "foo#mailserver.com", withPassword: "*********")
let operation = SendEmailOperation(to: "foo#mailserver.com", subject: "Hello", body: "world", path: "/selected/path/for/your/file.pdf")
operation?.completionBlock = {
debugPrint("Mail sent!")
DispatchQueue.main.async {
//showMailSentPopup()
}
}
do {
try SendEmailOperation.sendEmail(operation)
} catch {
debugPrint("Mail could not sent or sending result could not handle - \(error)")
}

Closed 11 years ago.
I am making an login application in which user can log in.
If the user has already register, then he should be able to log in with the same data saved on server and should be able to get alert view as success and if not the error alert.
Unfortunately, I am not able to do that.
Please help me out.
This is my code:
-(IBAction)btn_login: (id) sender
{
NSString *firstname = Firstname.text;
NSString *lastname = Lastname.text;
NSString *post = [NSString stringWithFormat:#"fname=%#&lname=%#",firstname,lastname];
NSString *hostStr =#"http://www.yoursite.com/iphone.php";
hostStr = [hostStr stringByAppendingString:post];
NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:hostStr]];
NSString *serverOutput = [[NSString alloc]initWithData:dataURL encoding:NSASCIIStringEncoding];
if ([serverOutput isEqualToString:#"Yes"])
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Congrats" message:#"You are authorised" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
}
else {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Error" message:#"Invalid Username and password" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
}
Firstname.text=nil;
Lastname.text=nil;
}
thanks
You need to supply a "?" after the address when appending parameters.
Change
NSString *hostStr=#"http://www.yoursite.com/iphone.php";
to
NSString *hostStr=#"http://www.yoursite.com/iphone.php?";
PS: NSData dataWithContentsOfUrl is a horrible way to do this. Use NSURLConnection and use authentication challenge for Basic Authentication. Read URL Loading System Programming Guide.
I've been building a rather complex system and there's come the time now where I want more concise debugging. I would like to display the contents of a variable (for this example an NSString called v_string) in a notification window (the kind of window that appear when you receive an SMS text).
Is there an easy way to just call an alert with a variable?
Thanks in Advance,
Dan
NSLog does not do? If not (like if you need to debug an application running on a disconnected device), you can extend the UIAlertView with a category:
#implementation UIAlertView (Logging)
+ (void) log: (id <NSObject>) anObject
{
NSString *message = [anObject description];
UIAlertView *alert = [[self alloc] initWith…];
[alert show];
[alert release];
}
And then in code:
NSString *anInterestingString = …;
[UIAlertView log:anInterestingString];
When you build the string to display in the alert window, simply append your variable's string represenation using stringByAppendingString.
Alert window is cumbersome. Use NSLog instead:
NSLog(#"Variable is: %#", v_string);
And in Xcode's console you will see that text.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"My Debug String" message:v_string delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[message show];
[message release];
I think this way you can see what you want.
But, as zoul said, why not to use NSLog(#"my var: %#", v_string); ?
Hope that it helps.
Trying to include a instance variable in a message that a UIAlertView Shows.
lostAlert = [[UIAlertView alloc] initWithTitle:#"Sorry" message:(#"You Were Wrong, the correct structure was %#", structureName) delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:nil];
however, when the Alert is shown, no message is shown.
Any ideas and help would be appreciated :)
Sam
did you try it with:
[NSString stringWithFormat:#"You Were Wrong, the correct structure was %#", structureName]
instead of
(#"You Were Wrong, the correct structure was %#", structureName)
I have a sting that is equal to a text field that i want to insert inside of a UIAlertView.
NSString *finalScore = [[NSString alloc] initWithFormat:[counter2 text]];
UIAlertView *myAlertView = [[UIAlertView alloc]
initWithTitle:finalScore
message:#"You scored X points"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"OK", nil];
[myAlertView show];
[myAlertView release];
I want to replace"X" with the score from the string "finalScore"
I know how to have it just with the score, you would simple just enter the strings name without quotes under the message section, but i want the the text there too along with the string.
Thanks a bunch,
Chase
Replace your message: parameter with:
message:[NSString stringWithFormat:#"You scored %# points", finalScore]
Also, note that your original code for finalScore uses string formatting without any arguments, which is either a no-op or unsafe (if it contains a % symbol). You are also leaking your finalScore object.
Try something like the following, and pass it as the message variable to UIAlertView's initialization:
NSString* message = [NSString stringWithFormat:#"You scored %# points",
[counter2 text]];
You might have to change some details about the formatting string depending on the type that comes out of [counter2 text], however, though the above should work in many of the cases you'll encounter.
Instead of:
#"You scored X points"
use:
[NSString stringWithFormat:#"You scored %# points", finalScore]
