How to end a UIKeyboardTypeDecimalPad

Gerriet M. Denkmann

I got a UITextField which has a UIKeyboardTypeDecimalPad.

With a normal TextField (UIKeyboardTypeDefault) the user can enter Return, the UITextFieldDelegate gets textFieldShouldReturn and all is well.

But how should the user tell the app that enough digits have been entered, as the DecimalPad has no Return key?
