sending sms programmatically in iphone

Question

How can you send an SMS programmatically to a particular number selected in the contact list in iPhone?

Answer 1

MFMessageComposeController is what you're looking for.

To send an SMS, you're looking at something like this:

#import <MessageUI/MessageUI.h>
@interface myClass : NSObject <MFMessageComposeViewControllerDelegate>{
}
@end

@implementation

-(void)sendMessage{
    if([MFMessageComposeController canSendText]){
        MFMessageComposeController *smsComposer =
                                       [[MFMessageComposeController alloc] init];

        smsComposer.recipients = [NSArray arrayWithObject:@"12345678"];
        smsComposer.body = @"SMS BODY HERE";

        smsComposer.delegate = self;

        [self presentModalViewController:smsComposer animated:NO];
    }
    else{
        //You probably want to show a UILocalNotification here.
    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller 
                                 didFinishWithResult:(MessageComposeResult)result{

    /* You can use the MessageComposeResult to determine what happened to the 
message. I believe it tells you about sent, stored for sending later, failed 
or cancelled. */

[self dismissModalViewControllerAnimated:NO];
}

@end

That's the only way to send SMSs from your app at the moment. Unless you just want to open the SMS app. If you aren't worried about the body of the message, you can do this:

NSString *smsURL = @"sms:12345678";
NSURL *url = [NSURL URLWithString:smsURL];
[[UIApplication sharedApplication] openURL:url];
