如何使用数组中的数字发送SMS？

Question

I have stored the contact numbers in an array and then passed this array to message controller like the below code and printed the value of controller.recipients and its showing null.

  MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
  NSArray *arr = [NSArray arrayWithArray:selContacts];
  controller.recipients = arr;
 NSLog(@"received:- %@",controller.recipients);
 controller.messageComposeDelegate = self;
 controller.body =@"https://itunes.apple.com/in/app/Click Here to Download!";
    if([MFMessageComposeViewController canSendText])
    {
        [self presentModalViewController:controller animated:YES];
    }

Answer 1

if(![MFMessageComposeViewController canSendText])
{
    UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your device doesn't support SMS!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [warningAlert show];
    return;

}
NSArray *recipents = @[@"+919999999999"];
NSString *message = @"Enter message here!";
MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
messageController.messageComposeDelegate = self;
[messageController setRecipients:recipents];
[messageController setBody:message];
// Present message view controller on screen
[self presentViewController:messageController animated:YES completion:nil];
