How to set a number key pad which contains the '-' key ?

You can add - yourself where you want to add like following code will add brackets ( and dash - while entering numbers in textfield.

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

    if (textField == self.mobileNumberField) {
        int length = [self getLength:textField.text];
        if(length == 10) {
            if(range.length == 0)
                return NO;
        }
        if(length == 3) {
            NSString *num = [self formatNumber:textField.text];
            textField.text = [NSString stringWithFormat:@"(%@) ",num];
            if(range.length > 0)
                textField.text = [NSString stringWithFormat:@"%@",[num substringToIndex:3]];
        }
        else if(length == 6) {
            NSString *num = [self formatNumber:textField.text];
            textField.text = [NSString stringWithFormat:@"(%@) %@-",[num substringToIndex:3],[num substringFromIndex:3]];
            if(range.length > 0)
                textField.text = [NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]];
        }
    }
    return YES;
}

{
    mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""];
    mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""];
    mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""];

    int length = [mobileNumber length];
    if(length > 10) {
        mobileNumber = [mobileNumber substringFromIndex: length-10];
    }
    return mobileNumber;

I think you can use the UIKeyboardTypePhonePad and use the inputAccessoryView property of UITextField for the - button.

Code:

UIToolbar *punctuationbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
numberToolbar.barStyle = UIBarStyleBlackTranslucent;
numberToolbar.items = [NSArray arrayWithObjects:
                       [[UIBarButtonItem alloc]initWithTitle:@"-" style:UIBarButtonItemStyleBordered target:self action:@selector(addHyphen)],
                       nil];
[numberToolbar sizeToFit];
_yourTextField.inputAccessoryView = punctuationbar;

And add the addHyphen method like:

- (void)addHyphen
{
  _yourTextField.text = [_yourTextField.text stringByAppendingString:@"-"];
}

Note: This method will append - at the end of the text. You need to modify the above method.

Reference:

inputAccessoryView

The custom accessory view to display when the text field becomes the first responder @property (readwrite, retain) UIView *inputAccessoryView;

Discussion

The default value of this property is nil. Assigning a view to this property causes that view to be displayed above the standard system keyboard (or above the custom input view if one is provided) when the text field becomes the first responder. For example, you could use this property to attach a custom toolbar to the keyboard. Availability
Available in iOS 3.2 and later.
