I'm having to update an enterprise app for use on 64-bit iOS devices running iOS 11 beta 3. The app composes an email which contains specific data, and the user sends the email to the server, where it is processed to extract the data. (I would prefer to send it to the server via TCP, but that was not my decision.)
The app is fully functional in that it will compose the email body with the specific data, address it to the server email box, and present the view with the "Send" button at the top. But tapping the "Send" button does nothing. For that matter, tapping the "Cancel" button only brings up that alert asking to make sure you want to cancel, and with either response, the email view is not dismissed.
Here's the Mail Compose code:
NSString *strEmailAddress = [[NSUserDefaults standardUserDefaults] objectForKey:kEmailAddress];
NSArray *listOfRecipients = [[NSArray alloc] initWithObjects:strEmailAddress, nil];
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setSubject:#"Equipment Inventory"];
[mailViewController setMessageBody:totalArray isHTML:NO];
[mailViewController setToRecipients:listOfRecipients];
[self presentViewController:mailViewController animated:YES completion:nil];
This is what I used in the previous 32-bit version of the app, and it has worked fine for over five years.
Because I'm dealing with betas for both iOS and Xcode, how can I figure out if this is a bug in the OS or in the code? No errors are shown either in Xcode or on the phone.
Thanks for any help.
You need to implement the delegate method and dismiss the controller.
the method will provide an error if accord.
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(nullable NSError *)error {
[controller dismissViewControllerAnimated:true completion:nil];
}
Does anybody know if it's possible, and how, to programmatically send a SMS from the iPhone, with the official SDK / Cocoa Touch?
Restrictions
If you could send an SMS within a program on the iPhone, you'll be able to write games that spam people in the background. I'm sure you really want to have spams from your friends, "Try out this new game! It roxxers my boxxers, and yours will be too! roxxersboxxers.com!!!! If you sign up now you'll get 3,200 RB points!!"
Apple has restrictions for automated (or even partially automated) SMS and dialing operations. (Imagine if the game instead dialed 911 at a particular time of day)
Your best bet is to set up an intermediate server on the internet that uses an online SMS sending service and send the SMS via that route if you need complete automation. (ie, your program on the iPhone sends a UDP packet to your server, which sends the real SMS)
iOS 4 Update
iOS 4, however, now provides a viewController you can import into your application. You prepopulate the SMS fields, then the user can initiate the SMS send within the controller. Unlike using the "SMS:..." url format, this allows your application to stay open, and allows you to populate both the to and the body fields. You can even specify multiple recipients.
This prevents applications from sending automated SMS without the user explicitly aware of it. You still cannot send fully automated SMS from the iPhone itself, it requires some user interaction. But this at least allows you to populate everything, and avoids closing the application.
The MFMessageComposeViewController class is well documented, and tutorials show how easy it is to implement.
iOS 5 Update
iOS 5 includes messaging for iPod touch and iPad devices, so while I've not yet tested this myself, it may be that all iOS devices will be able to send SMS via MFMessageComposeViewController. If this is the case, then Apple is running an SMS server that sends messages on behalf of devices that don't have a cellular modem.
iOS 6 Update
No changes to this class.
iOS 7 Update
You can now check to see if the message medium you are using will accept a subject or attachments, and what kind of attachments it will accept. You can edit the subject and add attachments to the message, where the medium allows it.
iOS 8 Update
No changes to this class.
iOS 9 Update
No changes to this class.
iOS 10 Update
No changes to this class.
iOS 11 Update
No significant changes to this class
Limitations to this class
Keep in mind that this won't work on phones without iOS 4, and it won't work on the iPod touch or the iPad, except, perhaps, under iOS 5. You must either detect the device and iOS limitations prior to using this controller, or risk restricting your app to recently upgraded 3G, 3GS, and 4 iPhones.
However, an intermediate server that sends SMS will allow any and all of these iOS devices to send SMS as long as they have internet access, so it may still be a better solution for many applications. Alternately, use both, and only fall back to an online SMS service when the device doesn't support it.
Here is a tutorial which does exactly what you are looking for: the MFMessageComposeViewController.
http://blog.mugunthkumar.com/coding/iphone-tutorial-how-to-send-in-app-sms/
Essentially:
MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
if([MFMessageComposeViewController canSendText])
{
controller.body = #"SMS message here";
controller.recipients = [NSArray arrayWithObjects:#"1(234)567-8910", nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
And a link to the docs.
https://developer.apple.com/documentation/messageui/mfmessagecomposeviewcontroller
You must add the MessageUI.framework to your Xcode project
Include an #import <MessageUI/MessageUI.h> in your header file
Add these delegates to your header file MFMessageComposeViewControllerDelegate & UINavigationControllerDelegate
In your IBAction method declare instance of MFMessageComposeViewController say messageInstance
To check whether your device can send text use [MFMessageComposeViewController canSendText] in an if condition, it'll return Yes/No
In the if condition do these:
First set body for your messageInstance as:
messageInstance.body = #"Hello from Shah";
Then decide the recipients for the message as:
messageInstance.recipients = [NSArray arrayWithObjects:#"12345678", #"87654321", nil];
Set a delegate to your messageInstance as:
messageInstance.messageComposeDelegate = self;
In the last line do this:
[self presentModalViewController:messageInstance animated:YES];
You can use a sms:[target phone number] URL to open the SMS application, but there are no indications on how to prefill a SMS body with text.
One of the systems of inter-process communication in MacOS is XPC. This system layer has been developed for inter-process communication based on the transfer of plist structures using libSystem and launchd. In fact, it is an interface that allows managing processes via the exchange of such structures as dictionaries. Due to heredity, iOS 5 possesses this mechanism as well.
You might already understand what I mean by this introduction. Yep, there are system services in iOS that include tools for XPC communication. And I want to exemplify the work with a daemon for SMS sending. However, it should be mentioned that this ability is fixed in iOS 6, but is relevant for iOS 5.0—5.1.1. Jailbreak, Private Framework, and other illegal tools are not required for its exploitation. Only the set of header files from the directory /usr/include/xpc/* are needed.
One of the elements for SMS sending in iOS is the system service com.apple.chatkit, the tasks of which include generation, management, and sending of short text messages. For the ease of control, it has the publicly available communication port com.apple.chatkit.clientcomposeserver.xpc. Using the XPC subsystem, you can generate and send messages without user's approval.
Well, let's try to create a connection.
xpc_connection_t myConnection;
dispatch_queue_t queue = dispatch_queue_create("com.apple.chatkit.clientcomposeserver.xpc", DISPATCH_QUEUE_CONCURRENT);
myConnection = xpc_connection_create_mach_service("com.apple.chatkit.clientcomposeserver.xpc", queue, XPC_CONNECTION_MACH_SERVICE_PRIVILEGED);
Now we have the XPC connection myConnection set to the service of SMS sending. However, XPC configuration provides for creation of suspended connections —we need to take one more step for the activation.
xpc_connection_set_event_handler(myConnection, ^(xpc_object_t event){
xpc_type_t xtype = xpc_get_type(event);
if(XPC_TYPE_ERROR == xtype)
{
NSLog(#"XPC sandbox connection error: %s\n", xpc_dictionary_get_string(event, XPC_ERROR_KEY_DESCRIPTION));
}
// Always set an event handler. More on this later.
NSLog(#"Received a message event!");
});
xpc_connection_resume(myConnection);
The connection is activated. Right at this moment iOS 6 will display a message in the telephone log that this type of communication is forbidden. Now we need to generate a dictionary similar to xpc_dictionary with the data required for the message sending.
NSArray *recipient = [NSArray arrayWithObjects:#"+7 (90*) 000-00-00", nil];
NSData *ser_rec = [NSPropertyListSerialization dataWithPropertyList:recipient format:200 options:0 error:NULL];
xpc_object_t mydict = xpc_dictionary_create(0, 0, 0);
xpc_dictionary_set_int64(mydict, "message-type", 0);
xpc_dictionary_set_data(mydict, "recipients", [ser_rec bytes], [ser_rec length]);
xpc_dictionary_set_string(mydict, "text", "hello from your application!");
Little is left: send the message to the XPC port and make sure it is delivered.
xpc_connection_send_message(myConnection, mydict);
xpc_connection_send_barrier(myConnection, ^{
NSLog(#"The message has been successfully delivered");
});
That's all. SMS sent.
Add the MessageUI.Framework and use the following code
#import <MessageUI/MessageUI.h>
And then:
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *messageComposer =
[[MFMessageComposeViewController alloc] init];
NSString *message = #"Your Message here";
[messageComposer setBody:message];
messageComposer.messageComposeDelegate = self;
[self presentViewController:messageComposer animated:YES completion:nil];
}
and the delegate method -
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
didFinishWithResult:(MessageComposeResult)result {
[self dismissViewControllerAnimated:YES completion:nil];
}
You can use this approach:
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:#"sms:MobileNumber"]]
iOS will automatically navigate from your app to the messages app's message composing page. Since the URL's scheme starts with sms:, this is identified as a type that is recognized by the messages app and launches it.
Follow this procedures
1 .Add MessageUI.Framework to project
2 . Import #import <MessageUI/MessageUI.h> in .h file.
3 . Copy this code for sending message
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *messageComposer =
[[MFMessageComposeViewController alloc] init];
NSString *message = #"Message!!!";
[messageComposer setBody:message];
messageComposer.messageComposeDelegate = self;
[self presentViewController:messageComposer animated:YES completion:nil];
}
4 . Implement delegate method if you want to.
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
///your stuff here
[self dismissViewControllerAnimated:YES completion:nil];
}
Run And GO!
//Add the Framework in .h file
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
//Set the delegate methods
UIViewController<UINavigationControllerDelegate,MFMessageComposeViewControllerDelegate>
//add the below code in .m file
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
MFMessageComposeViewController *controller =
[[[MFMessageComposeViewController alloc] init] autorelease];
if([MFMessageComposeViewController canSendText])
{
NSString *str= #"Hello";
controller.body = str;
controller.recipients = [NSArray arrayWithObjects:
#"", nil];
controller.delegate = self;
[self presentModalViewController:controller animated:YES];
}
}
- (void)messageComposeViewController:
(MFMessageComposeViewController *)controller
didFinishWithResult:(MessageComposeResult)result
{
switch (result)
{
case MessageComposeResultCancelled:
NSLog(#"Cancelled");
break;
case MessageComposeResultFailed:
NSLog(#"Failed");
break;
case MessageComposeResultSent:
break;
default:
break;
}
[self dismissModalViewControllerAnimated:YES];
}
Here is the Swift version of code to send SMS in iOS. Please noted that it only works in real devices. Code tested in iOS 7+. You can read more here.
1) Create a new Class which inherits MFMessageComposeViewControllerDelegate and NSObject:
import Foundation
import MessageUI
class MessageComposer: NSObject, MFMessageComposeViewControllerDelegate {
// A wrapper function to indicate whether or not a text message can be sent from the user's device
func canSendText() -> Bool {
return MFMessageComposeViewController.canSendText()
}
// Configures and returns a MFMessageComposeViewController instance
func configuredMessageComposeViewController(textMessageRecipients:[String] ,textBody body:String) -> MFMessageComposeViewController {
let messageComposeVC = MFMessageComposeViewController()
messageComposeVC.messageComposeDelegate = self // Make sure to set this property to self, so that the controller can be dismissed!
messageComposeVC.recipients = textMessageRecipients
messageComposeVC.body = body
return messageComposeVC
}
// MFMessageComposeViewControllerDelegate callback - dismisses the view controller when the user is finished with it
func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
}
2) How to use this class:
func openMessageComposerHelper(sender:AnyObject ,withIndexPath indexPath: NSIndexPath) {
var recipients = [String]()
//modify your recipients here
if (messageComposer.canSendText()) {
println("can send text")
// Obtain a configured MFMessageComposeViewController
let body = Utility.createInvitationMessageText()
let messageComposeVC = messageComposer.configuredMessageComposeViewController(recipients, textBody: body)
// Present the configured MFMessageComposeViewController instance
// Note that the dismissal of the VC will be handled by the messageComposer instance,
// since it implements the appropriate delegate call-back
presentViewController(messageComposeVC, animated: true, completion: nil)
} else {
// Let the user know if his/her device isn't able to send text messages
self.displayAlerViewWithTitle("Cannot Send Text Message", andMessage: "Your device is not able to send text messages.")
}
}
There is a class in iOS 4 which supports sending messages with body and recipents from your application. It works the same as sending mail. You can find the documentation here: link text
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
UIImage *ui =resultimg.image;
pasteboard.image = ui;
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"sms:"]];
}
//call method with name and number.
-(void)openMessageViewWithName:(NSString*)contactName withPhone:(NSString *)phone{
CTTelephonyNetworkInfo *networkInfo=[[CTTelephonyNetworkInfo alloc]init];
CTCarrier *carrier=networkInfo.subscriberCellularProvider;
NSString *Countrycode = carrier.isoCountryCode;
if ([Countrycode length]>0) //Check If Sim Inserted
{
[self sendSMS:msg recipientList:[NSMutableArray arrayWithObject:phone]];
}
else
{
[AlertHelper showAlert:#"Message" withMessage:#"No sim card inserted"];
}
}
//Method for sending message
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSMutableArray *)recipients{
MFMessageComposeViewController *controller1 = [[MFMessageComposeViewController alloc] init] ;
controller1 = [[MFMessageComposeViewController alloc] init] ;
if([MFMessageComposeViewController canSendText])
{
controller1.body = bodyOfMessage;
controller1.recipients = recipients;
controller1.messageComposeDelegate = self;
[self presentViewController:controller1 animated:YES completion:Nil];
}
}
If you want, you can use the private framework CoreTelephony which called CTMessageCenter class. There are a few methods to send sms.
Use this:
- (void)showSMSPicker
{
Class messageClass = (NSClassFromString(#"MFMessageComposeViewController"));
if (messageClass != nil) {
// Check whether the current device is configured for sending SMS messages
if ([messageClass canSendText]) {
[self displaySMSComposerSheet];
}
}
}
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
//feedbackMsg.hidden = NO;
// Notifies users about errors associated with the interface
switch (result)
{
case MessageComposeResultCancelled:
{
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:#"Message" message:#"SMS sending canceled!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alert1 show];
[alert1 release];
}
// feedbackMsg.text = #"Result: SMS sending canceled";
break;
case MessageComposeResultSent:
{
UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:#"Message" message:#"SMS sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alert2 show];
[alert2 release];
}
// feedbackMsg.text = #"Result: SMS sent";
break;
case MessageComposeResultFailed:
{
UIAlertView *alert3 = [[UIAlertView alloc] initWithTitle:#"Message" message:#"SMS sending failed!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alert3 show];
[alert3 release];
}
// feedbackMsg.text = #"Result: SMS sending failed";
break;
default:
{
UIAlertView *alert4 = [[UIAlertView alloc] initWithTitle:#"Message" message:#"SMS not sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alert4 show];
[alert4 release];
}
// feedbackMsg.text = #"Result: SMS not sent";
break;
}
[self dismissModalViewControllerAnimated: YES];
}
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:#"sms:number"]]
This would be the best and short way to do it.
You can present MFMessageComposeViewController, which can send SMS, but with user prompt(he taps send button). No way to do that without user permission. On iOS 11, you can make extension, that can be like filter for incoming messages , telling iOS either its spam or not. Nothing more with SMS cannot be done
You need to use the MFMessageComposeViewController if you want to show creating and sending the message in your own app.
Otherwise, you can use the sharedApplication method.
I try to send e-mail from my IOS app but it does not work. I have tried lots of different tutorials, test it on a real iPhone. I have implemented MFMailComposeViewControllerDelegate, imported MessageUI / MessageUI.h in the h file. When the message is opened the subject is there but not the message itself and not to whom the message should be sent to(Recipient). Both are empty, and the message can not be sent. I do not understand what the problem is I have followed 10 different tutorials but none works. I work in Xcode 7 (objective c).
You have to add the recipients in the recipient array and pass it to MFMailComposeViewController. Like this:
if([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController* mail = [[MFMailComposeViewController alloc] init];
[mail setMailComposeDelegate:self];
[mail setSubject:#"Test Subject"];
[mail setMessageBody:#"Stannis Baratheon is the one true King....Also this is a test email" isHTML:NO];
NSArray *arrayOfRecepients = [[NSArray alloc] initWithObjects: #"test#gmail.com",#"test#yahoo.com",nil];//Add as many email addresses as you want. For single email, add only one email in this array
[mail setToRecipients:arrayOfRecepients];
[self presentViewController:mail animated:YES completion:NULL];
}
I am assuming that you are not adding recipients correctly. I am waiting for your response to Russell's comment to show us your code to correctly determine what is wrong with your code. I will then update the answer if need be.
When i restarded my phone it worked, so if this happends try to restart your IOS device
I am getting the PK Payment auth view controller instance returned as nil. What is wrong with this code?
if([PKPaymentAuthorizationViewController canMakePayments])
{
if ([PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:#[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa]])
{
PKPaymentRequest *request = [[PKPaymentRequest alloc] init];
request.currencyCode = #"USD";
request.countryCode = #"US";
request.merchantCapabilities = 0;
request.requiredBillingAddressFields=PKAddressFieldAll;
request.merchantIdentifier = #"merchant.com.domain.mine";
PKPaymentSummaryItem *item = [[PKPaymentSummaryItem alloc] init];
item.label=#"Merchant";
item.amount=[NSDecimalNumber decimalNumberWithString:#"10"];
request.paymentSummaryItems=#[item];
PKPaymentAuthorizationViewController *viewController = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];
viewController.delegate = self;
[self presentViewController:viewController animated:YES completion:nil];
}
}
Before accessing the PKPaymentAuthorizationViewController, you should configure Apple Pay properly on your iPhone device. If you have not configured Apple Pay on your device you'll get nil value for PKPaymentAuthorizationViewController. You can even find an exception on the console stating "This device cannot make payment."
To configure Apple Pay on your device follow the below steps:
Go to Settings.
Select Passbook and Apple Pay option (if this option is not visible in settings, go to General -> Language & Region, change your region to US or UK, after this you'll be able to see the Passbook & Apple Pay option in Settings)
Open Passbook application from your home screen and configure a valid credit/debit card (US/UK based card only).
After verifying the added card, run your application you'll get a valid PKPaymentAuthorizationViewController instance.
Hope this will help.
I had a similar issue. It looks like you included it, but for anyone else struggling with this, my problem was not initially supplying merchantCapabilities to the request.
Swift:
request.merchantCapabilities = PKMerchantCapability.capability3DS
https://developer.apple.com/documentation/passkit/pkmerchantcapability?language=objc
If you are instantiating the supporting networks with raw value, make sure they are done so with the proper capitalization.
// Summarized for posting purposes
let networks = ["AmEx", "Visa", "MasterCard", "Discover"].reduce(into: [PKPaymentNetwork]()) { $0.append(PKPaymentNetwork($1)) }
if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: networks, capabilities: .capability3DS) {
// Hooray
}
I wanna set a button inside my app that, if clicked, app can jump to the default mailbox of iOS. I want to do this so users can check & send their mails.
Does this function need a private API or is this forbidden by Apple?
Thanks in advance for your kind help.
This does what you want:
let app = UIApplication.shared
if let url = NSURL(string: "message:"), app.canOpenURL(url) {
app.openURL(url)
}
The canOpenURL part checks if the user has got at least one email address setup in Mail that they can send/receive from.
Maybe you can use the url scheme like this:
NSString *email = #"mailto:?subject=YourSubject&body=MsgBody";
email = [email stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString:email]];
To Send an email from within your app, one of the first 2 answers will work: MFMailComposeViewController or using the url scheme mailto://.
As for checking the users email, there is currently no public way to launch the default iOS mail application. There are however a few 3rd party libraries available to allow you to set up your own mail client, for example MailCore, remail or Chilkat. I'm sure there are others but you get the idea.
How about using MFMailComposeViewController? You can set its subject, recipients, message body, the attachment, and then you can present it modally within your app. It will be better too since the user does not need to leave your app.
if ([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setSubject:subjectString];
[mailViewController setMessageBody:messageString isHTML:YES];
[self presentViewController:mailViewController animated:YES completion:nil];
}
Just remember to set the view controller calling the function above as the delegate of MFMailComposeViewControllerDelegate so that you can dismiss the view controller afterwards.
-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self dismissViewControllerAnimated:YES completion:nil];
}
