From my app I want to open the phone\'s dialer keypad which is used to make phone call. I tried as
[[UIApplication sharedApplication] openURL:[NSURL URLWithStrin
Its not possible to open the Phone's keypad. You can design your own phone pad in your view controller, add DTMF Tones for sounds and make it look like a phone's keypad. If you want your own phonepad and want to have it within your app then this is the only way.
It is possible to open the Phone app and execute a call if you want,refer to the link below to know how its done.
Make a phone call programmatically
