Assume self.textField is a UITextField where you can enter the number. Then add the following event listener listener to your ‘call’ button:

- (IBAction)makeCall{
    NSURL *target = [[[NSURL alloc] initWithString:[NSString stringWithFormat:@"tel:%@", self.textField.text]] autorelease];
    [[UIApplication sharedApplication] openURL:target];    
}
