In iOS 4.1, there is a number pad with a decimal point available. You can select it programatically (in case you are supporting versions of iOS before 4.1) like so:

inputBoxTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation;
if (([[[UIDevice currentDevice] systemVersion] doubleValue] >= 4.1)) {
    inputBoxTextField.keyboardType = UIKeyboardTypeDecimalPad;
}

You could choose any appropriate keyboard type (line 1). In this case, NumbersAndPunctuation includes a period in case the user's iOS version is before 4.1.

In Swift:

priceText.keyboardType = .decimalPad

In iOS 8 or above follow these steps:

1. Select the Textfield in Interface Builder
2. Edit Keyboard Type in xib or Storyboard
3. Select Decimal Pad

I have developed an open source custom decimal keyboard. Methods and implementations are very easy to use and you can change buttons or add/remove extra buttons as you see fit. Please have at look at the repository here TD-DecimalKeyboard and feel free to fork and contribute.
