Dial number in iOS really need confirmation?

Question

I am using the following code to dial number and testing with my device. It seems no confirmation is needed, correct?

NSURL *url = [NSURL URLWithString:@"tel://12345678"];
[[UIApplication sharedApplication] openURL:url];

Answer 1

An alternative to the suitable solution already posted, you could consider using the telprompt URL scheme, e.g.

NSURL *url = [NSURL URLWithString@"telprompt://12345678"];
[[UIApplication sharedApplication] openURL:url];

Answer 2

Confirmation isn't required and isn't shown when done programmatically. You will only see the alertView in Safari if a number is clicked.

However, in my own experience, I believe it's more convenient for the customer to see a dialog box so they don't accidentally call someone. People just tap things in apps without even thinking and that could be bad in this case.

To mimic what safari does you can do something like this:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Call 12345678?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Call", nil];
[alert show];
alert.tag = 1;
[alert release];

and

-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    switch (alertView.tag) {
        case 1:
            if (buttonIndex == 1) {
                NSURL *url = [NSURL URLWithString:@"tel://12345678"];
                [[UIApplication sharedApplication] openURL:url];
            }
            break;
        default:
            break;
    }
}
