iPhone: make a call

问题

Is there a way for my app to call a certain number and to play a certain sound?

Thanks.

回答1:

You can call a number by requesting the URL tel://###-###-###, but this will quit your application and launch the iPhone's default phone application. There is no way of playing a sound as your application has exited at that point.

回答2:

[[UIApplication sharedApplication]
  openURL:[NSURL URLWithString:@"tel://91-123******"]];
