UIKeyboardTypeNumberPad - Show just numbes on iPad?

Question

UIKeyboardTypeNumberPad doesn't display a number pad on the iPad. Instead, it shows the UIKeyboardTypeNumbersAndPunctuation keyboard.

Is there something I'm missing, or has this been removed from the iPad OS?

Thanks for your guidance!

Answer 1

I believe that this is not currently supported in iPhoneOS 3.2 on the iPad

To quote the UITextInputTraits header file:

//
// UIKeyboardType
//
// Requests that a particular keyboard type be displayed when a text widget
// becomes first responder. 
// Note: Some keyboard/input methods types may not support every variant. 
// In such cases, the input method will make a best effort to find a close 
// match to the requested type (e.g. displaying UIKeyboardTypeNumbersAndPunctuation 
// type if UIKeyboardTypeNumberPad is not supported).
//

add UITextFieldDelegate in your header file (.h file)

txtfield_name.keyboardType=UIKeyboardTypeNumbersAndPunctuation;
txtfield_name.delegate=self;

then add this method

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{

 NSString *validRegEx =@"^[0-9]*$"; //change this regular expression as your requirement
 NSPredicate *regExPredicate =[NSPredicate predicateWithFormat:@"SELF MATCHES %@", validRegEx];
 BOOL myStringMatchesRegEx = [regExPredicate evaluateWithObject:string];
 if (myStringMatchesRegEx)
        return YES;
 else
        return NO;
}
