[IPhone] Send SMS sample with IPhone

Introduction

I will demo some sample to present how to send SMS in iphone programming.

Sample 1

The easiest way is this demo.

[[UIApplication sharedApplication] openURL: @"sms:12345678"];

HTML links:  
<a href="sms:" mce_href="sms:">Launch Text Application</a>   
<a href="sms:1-408-555-1212" mce_href="sms:1-408-555-1212">New SMS Message</a>   
 
Native application URL strings:  
 
sms:   
sms:1-408-555-1212

Sample 2

We can use MessageUI Framework and MFMessageComposeViewController to send SMS.

-(IBAction) sendInAppSMS:(id) sender
{
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = @"Hello from Mugunth";
        controller.recipients = [NSArray arrayWithObjects:@"12345678", @"87654321", nil];
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
}

You have to handle a callback method of MFMessageComposeViewControllerDelegate so as to dismiss the modal view controller.

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    switch (result) {
        case MessageComposeResultCancelled:
            NSLog(@"Cancelled");
            break;
        case MessageComposeResultFailed:
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"MyApp" message:@"Unknown Error"
                                                           delegate:self cancelButtonTitle:@”OK” otherButtonTitles: nil];
            [alert show];
            [alert release];
            break;
        case MessageComposeResultSent:

            break;
        default:
            break;
    }

    [self dismissModalViewControllerAnimated:YES];
}

Sample 3

This is a full sample code for MFMessageComposeViewController.

    UILabel *message;
}
@property (nonatomic, retain) UILabel *message;

@end

//  SMS2
#import "SMS2ViewController.h"

    }
    return self;
}
