I am writing code to send sms programatically
Program crashes at second last line.
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;
picker.recipients = [NSArray arrayWithObject:#"123456789"]; // your recipient number or self for testing
picker.body = #"test from OS4";
[self presentModalViewController:picker animated:YES];
[picker release];
I assume it's safe to say that it implements
UIViewController <MFMessageComposeViewControllerDelegate>
In which case, I would recommend going back to http://iphonesdkdev.blogspot.com/2010/04/mfmessagecomposeviewcontroller-sample.html, copying their example and progressing from there.

I was trying to send SMS from within my app. I wrote this piece of code but it seems not to work.
No crash, no error log, simply nothing happen (of course I tried to log canSendText and the result is 1).
- (void)viewDidLoad
{
[super viewDidLoad];
messageComposer = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText]) {
[messageComposer setBody:#"Messaggio generato da SMSTest"];
[messageComposer setRecipients:[NSArray arrayWithObject:#"3333333333"]];
[messageComposer setDelegate:self];
[self presentModalViewController:messageComposer animated:YES];
}
}
Can anyone explain me what I'm doing wrong?
The problem is that presentModalViewController does not work in viewDidLoad yet as the view is loaded but might not even be on screen yet. If you put your code in viewWillAppear:animated, this should work.
Edit: As per Saphrosit's comment: viewDidAppear: is an even better place to do this.
I use this successfully:
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
controller.messageComposeDelegate = self;
controller.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:controller animated:YES];
Note that it's messageComposeDelegate, not 'delegate' as you do.

When i try the code on simulator i get an UIAlert saying text messaging is not available, because simulator can´t send messages. Have you checked that your header file is a delegate of MFMessageComposeViewControllerDelegate ?
YourClassName : UIViewController <MFMessageComposeViewControllerDelegate>
//try this ... it will run ..
MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
if([MFMessageComposeViewController canSendText])
{
controller.body = #"Hello from Kartik";
controller.recipients = [NSArray arrayWithObjects:#"12356478", nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
I have a method like this:
void sendSMS{
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.recipients = [NSArray arrayWithObject:#"0933660805"];
[picker setBody:#"Message body"];
picker.messageComposeDelegate = self;
[self.navigationController presentModalViewController:picker animated:YES];
//[picker release];
return;
}
}
Message composer open but recipients and message body are empty (image below). Anybody know how can i fix it :(
Go for this ones and then check may be it will resolve your issue
void sendSMS
{
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;
NSString *bodyString = nil;
NSMutableArray *toRecipients = [[NSMutableArray alloc]init];
[toRecipients addObject:#"0933660805"];
[picker setRecipients:(NSArray *)toRecipients];
[toRecipients release];
bodyString = [NSString stringWithFormat: #"Message body"];
[picker setBody:bodyString];
[self presentModalViewController:picker animated:YES];
[picker release];
}
Also take a look at this tutorial http://blog.mugunthkumar.com/coding/iphone-tutorial-how-to-send-in-app-sms/
Good Luck!
OK I answered my own question. Now I want no one else to have to go thru this. I was calling this method from just an NSObject. It was a delegate to MFMessageComposeViewControllerDelegate but that made no difference. I had to move this method to my MainViewController, then it worked.
iOS 10.0 is here and this is still a problem for me. So, I have fashioned a workaround.
According to previous comments that initializing the MFMessageComposeViewController in the viewDidLoad() won't solve the problem (which I can attest to), unless the view controller gets presented, it won't be cached. So, the hack here is to make a window, set its root view controller, present a dummy MFMessageComposeViewController instance and immediately dismiss it, somewhere before your actual need (like in viewDidLoad())
Here is a sample code I'm using (Swift 3.0 - Let me know if you were interested in Obj-C counterpart):
let window = UIWindow()
let vc = UIViewController()
window.rootViewController = vc
let messageCompose = MFMessageComposeViewController()
vc.present(messageCompose, animated: false) { [weak messageCompose] in
messageCompose?.dismiss(animated: false, completion: nil)
}
The thing here is that if you present it in the currently active window's view controller chain, it will mess up your UI by showing and hiding the keyboard abruptly (no matter how you try to hide the controller's view and what not), due to the message body selection on present. But adding it to a whole new window which is not in view cycle, it will be correctly initialized and there will be no trace of such transaction on view. Plus, you won't boggle the memory too much this way (because the scope of the controller should be minimal now) and you can initialize your actual MFMessageComposeViewController any time you want and get it much faster now. If your application heavily relies on MFMessageComposeViewController (which I doubt) you can move this to your AppDelegate to be ready anywhere around your app's life cycle.
Cheers,

Try this
- (void)sendSMS
{
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;
NSString *bodyString = nil;
NSArray *toRecipients = [NSArray arrayWithObject:#"NUMBER HERE"];
[picker setRecipients:toRecipients];
[self presentModalViewController:picker animated:YES];
[picker release];
}
In my case (on iPhone 3g s) the problem was when I called [self.navigationController pushViewController... ], when i tried call [self presentModalViewController ...] it worked, I dont know why, but it is. Try it.
set the MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
before if ([MFMessageComposeViewController canSendText]) {...}
Try this.
Try this.
- (void)forwardPromo
{
MFMessageComposeViewController *composeViewController = [[MFMessageComposeViewController alloc] init];
composeViewController.body = #"Message body";
composeViewController.recipients = [NSArray arrayWithObject:#"0933660805"];
composeViewController.messageComposeDelegate = self;
[self presentViewController:composeViewController animated:YES completion:nil];
}
You should have a "nil" at the end of the array:
composeViewController.recipients = [NSArray arrayWithObject:#"0933660805", nil];
I'm using MFMessageComposeViewController for in-app SMS. The problem is that when I have an NSString with whitespace to assign to body, it will remove all whitespaces. Below code demonstrates the issue. Interesting thing is that it works when I try to copy the same text to clipboard and paste into the sms app.
- (void)sendSMS {
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText])
{
[controller setBody:#" aaa aaa"];
controller.recipients = [NSArray arrayWithObjects:nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
[controller release];
}
//it becomes "aaa aaa" on the SMS message box when controller shows up.
Does anybody have any idea how to solve this problem?
Thanks in advance!
This seems to still be a problem 5/2012. However you can force the whitespace with  . Not the best option, but it works. The MFMailComposeController will also drop leading whitespace on the body and the same method works.
Iphone 4 MFMailComposeViewController
MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setMessageBody:#"Welcome" isHTML:NO];
[controller release];
My app to be crash.
Wat i did wrong
Regards,
Arun
The mail composer will crash if the user is unable to send mail. First check to see if the user is able to send mail before trying to instantiate a MFMailComposeViewController.
if([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController* controller = [[[MFMailComposeViewController alloc] init] autorelease];
//...
}
#Arun , First up all configure the email settings in your device
As Akira says, you can use MFMailComposeViewController after you set up the device's e-mail settings.
init failed, because not iOS mail-application's setting.
MFMailComposeViewController* controller = [[[MFMailComposeViewController alloc] init] autorelease];
if (!controller) // failed
return; // auto view alert, "not mail setting..."
controller.mailComposeDelegate = self;
In my application, MFMailComposeViewController works fine but creating a new instance of MFMessageComposeViewController fails.
Here is the code for both:
-( IBAction)sendSMS: (id)sender
{
MFMessageComposeViewController *picker = [[[MFMessageComposeViewController alloc] init] autorelease];
picker.messageComposeDelegate = self;
NSArray *toRecipients = [NSArray arrayWithObject: cell.currentTitle ];
picker.recipients = toRecipients;
[self presentModalViewController:picker animated:YES];
}
-( IBAction)sendEmail: (id)sender
{
MFMailComposeViewController *picker = [[[MFMailComposeViewController alloc] init] autorelease];
picker.mailComposeDelegate = self;
NSArray *toRecipients = [NSArray arrayWithObject: email.currentTitle ];
[picker setToRecipients:toRecipients];
[self presentModalViewController:picker animated:YES];
}
Its seemingly obvious that everything is linking correctly because the email view controller works fine. Is there something I am missing maybe configuration wise?
Have you checked +[MFMessageComposeViewController canSendText]?
From the MFMessageComposeViewController Class Reference,
Before presenting a message composition view, call the canSendText class method to ensure that the user’s device is appropriately configured. Do not attempt to present a message composition view if the canSendText method returns NO. If SMS delivery isn’t available, you can notify the user or simply disable the SMS features in your application.
Starting in iOS 5, you can register to be notified of changes to the availability of text message sending by way of the MFMessageComposeViewControllerTextMessageAvailabilityDidChangeNotification notification.
Reasons it might be returning nil:
Device isn't running iOS 4.
Device is an iPod Touch/iPad without iMessage enabled.
No SIM card? (The view now shows in iOS 6; the app is not notified of the message send failure.)
"Device" is actually the simulator. (Perhaps this works in iOS 6 too.)
Similarly, [[MFMailComposeViewController alloc] init] returns nil when no mail accounts are enabled (you can quickly test this by disabling accounts in Settings), but also shows a "No mail accounts configured" alert for you. MFMessageComposeViewController does not do this.
