I wrote a Hello World app, and put the following code in ...ViewController.m:
- (void)viewDidLoad {
[super viewDidLoad];
CTTelephonyNetworkInfo *networkInfo = [[CTTelephonyNetworkInfo alloc] init];
networkInfo.subscriberCellularProviderDidUpdateNotifier = ^(CTCarrier *carrier) {
[[[UIAlertView alloc] initWithTitle:#"SIM Alert"
message:#"This is an alert."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
};
}
Then I unplugged the SIM card but no alert was shown as expected. Could someone kindly tell me what's wrong? Thanks.
This is the ultimate solution to your question.
CTTelephonyNetworkInfo *networkInfo = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [networkInfo subscriberCellularProvider];
NSString *mobileNetworkCode = [carrier mobileNetworkCode];
[networkInfo release];
NSLog(#"Mobile Network Code : %#", mobileNetworkCode);
Depending on the mobileNetwork code you can determine whether SIM is present or not on the Device.
If you have a look at apples documentation of CTCarrier some properties, for example carrierName, have a short notice like this:
If you configure a device for a carrier and then remove the SIM card, this property retains the name of the carrier.
So I would guess the same happens for the rest of the API, since the SIM card isn't replaced by a new one the updateNotifier isn't called.

Is it possible to do retrieve the gmail account detail into the app?
Please help me out with this.

What i want to do is i want to access user gamil account details from
setting tab of the iPhone into my app? is it possible to do retrive
the gamil account detail into the app?
No, and with good reason: that functionality would allow any developer access to anyone's e-mail account.
That would be a massive security hole.
Much like it is with Location Services, you're just going to have to ask the user to enter their e-mail address and password. And hope they want to trust your app with that kind of personal information. (Assuming Apple approves your app at all.)
Let the user give your app authorization from Google. check the oauth autorization with google api at their developers site?
https://developers.google.com/accounts/docs/OAuth2
As usual the user signs in with his account through google api and returns back to you an access_token to get information back from his account including his email which you need.
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]);
}
https://github.com/troyz/MailUtil
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)")
}
I am trying to generate an UIActionSheet from a NSDictionary.
codeCountryMap is NSDictionary variable defined in .h file. The code compiled correctly but crashes on run time. But the whole code works when the initialization is done in the handleEvents method
- (void)viewDidLoad {
[super viewDidLoad];
NSArray *codes = [NSArray arrayWithObjects:#"91", #"01", #"002", nil];
NSArray *cName = [NSArray arrayWithObjects:#"ABC", #"QWE", #"XYZ", nil];
codeCountryMap = [NSDictionary dictionaryWithObjects:codes forKeys:cName];
}
-(IBAction) handleEvents:(id)sender
{
UIActionSheet *displayCodeCountryMap = [[UIActionSheet alloc] initWithTitle:#"Select Country" delegate:self cancelButtonTitle:nil
destructiveButtonTitle:nil otherButtonTitles:nil,nil];
for(id key in codeCountryMap) {
[displayCodeCountryMap addButtonWithTitle:(NSString *)key];
}
[displayCodeCountryMap addButtonWithTitle:#"Cancel"];
displayCodeCountryMap.cancelButtonIndex = [codeCountryMap count];
displayCodeCountryMap.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[displayCodeCountryMap showInView:self.view];
[displayCodeCountryMap release];
[country resignFirstResponder];
}
The app crashes when the handleEvents: method is called.
Any kind of help would be greatly appriciated.
Thanks in advance.
This more than likely is a memory management issue. It looks like you are setting the iVar codeCountryMap to an autoreleased object of NSDictionary and not retaining it(at least not in this code snippet). This means that when the 'handleEvents' method is called the NSDictionary item has been released from memory.
Try either retaining the NSDictionary item or, if codeCountryMap is defined as a retained property, then use the following code to set it.
self.codeContryMap = [NSDictionary dictionaryWithObjects:codes forKeys:cName];
This will use the synthesized methods to set the property and retain it.
No need for 2 nils terminators in the otherButtonTitles argument. If you had passed in strings then it would have to be nil terminated. Since you did not, one nil is enough.
UIActionSheet *displayCodeCountryMap = [[UIActionSheet alloc] initWithTitle:#"Select Country" delegate:self cancelButtonTitle:nil
destructiveButtonTitle:nil otherButtonTitles:nil];
I use the simple FBStreamDialog example in my iPad app:
FBStreamDialog* pDialog = [[[FBStreamDialog alloc] init] autorelease];
pDialog.delegate = self;
pDialog.userMessagePrompt = #"Example prompt";
pDialog.attachment = #"{\"name\":\"Facebook Connect for iPhone\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone\",\"caption\":\"Caption\",\"description\":\"Description\",\"media\":[{\"type\":\"image\",\"src\":\"http://img40.yfrog.com/img40/5914/iphoneconnectbtn.jpg\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}";
NSLog(#"prompt: %#", pDialog.userMessagePrompt);
NSLog(#"attachment: %#", pDialog.attachment);
[pDialog show];
NSLogs are OK.
The problem is that neither message prompt nor attachment are shown in FBStreamDialog.
Can anyone help?
The problem was in simulator. It works on device.
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.
