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
You can use it by setting a property in UITextField keyboardtype .
selectedTextField.keyboardType=UIKeyboardTypePhonePad;
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
