ios - 如何使用数组中的号码发送短信？

Question

我将联系人号码存储在一个数组中，然后像下面的代码一样将该数组传递给消息 Controller 并打印 controller.recipients 的值及其显示为 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];
