IOS: textfield and double value

I have this situation:

I should write in a text field a value in euro. If inside this text field I write "10" I should store in a double value "10.00" or if I write "10,1" I should store in a double "10,10" or if I write "10,23" I should store "10,23"

How can I do it?

You can use the typecasting like convert string to double value.

If you want to support localized numbers (e. g. user input), -[NSNumberFormatter numberFromString:] is the way to go. Since this returns an NSNumber you can get the double value using -[NSNumber doubleValue]:

NSNumber *number = [numberFormatter numberFromString:inputString];
double doubleValue = [number doubleValue];

This should help:

double val = [[textField text] doubleValue];
