iPhone SDK Make a call programmatically

Tuesday

IPhone SDK dial a phone number:

                                        Use the UIApplication openURL method passing a URL that starts with 'tel:'.

use the tel:// url, just like you would want to navigate to a web page with an http:// url. you may use this as a hyperlink on a web page, or button for your Apps. You simply need to call it with a URL of the form.

Code for Making a phone call from iPhone Apps :

NSString *phone_number = @"1-900-444-1000";      // you can assign dynamically 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phone_number]]];
