Question

I want the user to be able to call a phone number form within my app. Is it possible for the user to be returned straight back to the application after finishing the call?

Answer 1

1: I guess that this is the default behavior, isn’t it?

2: you can check if the device can open the tel:// protocol:

BOOL canCall = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"tel://"]];
