In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols.

Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final result?

Thanks!
