Question

Is there a way to use the SMS URL to open the SMS app with multiple recipients? I’ve tried similar approaches to the mailto: protocol but it’s not playing nice.

Answer 1

Starting with iOS 4.x you can include multiple recipients as shown below:

MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

controller.recipients = [NSArray arrayWithObjects:@"1-222-333-4444", @"1-222-333-5555", nil];
