Making a Button Call a Phone Number in iOS [duplicate]

Answer 1

Try this out in your button action

-(IBAction)callPhone:(id)sender {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1115550123"]];
}

Then in Interface Builder you should connect the TouchUpInside event to the previously declared action (callPhone:) and you are done.

Answer 2

You can also go back to your original app when finish the call just by using this one instead:

-(IBAction)callPhone:(id)sender {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://2135554321"]];
}

Enjoy!
