xcode - iPhone: How can I add a currency symbol, decimal point and decimal places in shouldChangeCharactersInRange -

I have found the code given below, which should I am trying to work in UITableView ChangeCharactersInRange event without currency symbol It works fine.

When I try to add the currency symbol, it allows me to enter a number. What should I do, say that I enter 7536, it should be £ 0.07, £ 0.75, £ 7.53, £ 75.36, but instead it is £ 0.07, £ 0.05, £ 0.03, £ 0.06
